If the computer is in an AD domain and protected by something like BitLocker, swapping the CPU might invalidate the keys in the TPM, which you might have to ask your network admin for (I've seen field service in some companies just giving them away if you ask nicely, especially since they sometimes spontaneously invalidate after BIOS updates or whatever, but it might raise some suspicion). I don't know whether a network admin could be actively notified of hardware changes like this, though.

Yeah, a while ago I tried installing some miner software and a few other programs, but everything asks for admin permission. Workaround for this?

>>3158
There's a young I.T guy that comes around every now and again that I'm friends with. He does all the BIOS updates from what I can tell. Maybe he has the keys you're talking about? I also thought that maybe I could just play dumb and say my computer isn't working and have them install the driver's you're talking about.

I agree, I apologize. I was having a rage fit and couldn't type anything that remotely resemble an actual thought. This week I've been having uncountable such fits. I actually broke my favourite milk mug during one of these. I had that mug since I was little kid. I did not meant to post such an unseemly post. I have deleted it and after calming myself down and refusing to hit any expensive piece of technology, I have came up with a solution. Please forget I've ever posted that.

Bit of a long shot, but thought I might as well ask.
For a while I've had this issue with "micro stuttering" in games, only I think it's more than that. sometimes FPS drops into the 40s. When I first started to really notice this I thought it was the higher end game I was trying to play (RDR2), so I went and got a better GPU. I found it was still doing it. I read the game was poorly ported, so I assumed it was possibly just that. I was also forced to limit my power usage, as it was setting off my backup battery. I was also running it on an HDD.

I've been playing HL2 lately, off an SSD. A game that by all means should run on max settings flawlessly even with cheap old junk hardware. Yet it runs about as smooth as sandpaper.
The image included was taken as I left Half Life 2 running. I touched nothing and nothing was moving on screen, it was just a static frame. FPS generally stayed around 56-60, but would drop to 45fps almost regularly.
Some of my hardware is a little on the older side now, but even then a game this old should run fine shouldn't it?

My PC specs i7-4790k @4.00gz, 24gb DDR3 overclocked ram, HX-750i. asrock z97 extreme3, RTX-3080. on Win10 LTSC.

So far I've tried updating graphic drivers (with a clean removal of the old ones), Disabling microsoft's gamebar and game mode, and blocking almost everything that starts with my pc then running the game with nothing in the background. I've also tried disabling v-sync in game and applying it via the nvidya control panel, and vice versa.
I considered getting a monitor with g-sync, but because of those 40fps dips I'm not sure if that would even help.
Or is my rig maybe just too old and janky?
>> No. 3191 [Edit]
>>3190
Not a gamer but those specs should handle Half-Life 2 easily (it runs smooth even on integrated graphics of my laptop, albeit not without getting toasty). Not sure how to interpret that graph or what the scale is, the GPU temperature looks a bit odd, it seems like it should steady state yet I see fluctations. Try manually cranking fan speed to max and seeing if it delays the onset of the issue? I'm not familiar with windows system debugging tools, I think Russinovich's tools (Sysinternals et al.) are the gold standard there.

G-sync will technically help in making the stutter less noticeable, but it doesn't solve the root issue. You shouldn't be limited by IO, CPU, or GPU based on those specs.
>> No. 3192 [Edit]
>>3191
Yeah the graph is a bit weird. The text for each readout is just above it.
FPS is the top one. GPU usage is bellow that, and temp is pretty consistent at 40

This is what it looks like during gameplay. I should also point out that I've seen this kinda thing in the past outside of games too for years. Like while watching anime, scenes where the frame pans over a shot would be very jerky. I guess I kinda just learned to live with it.
>> No. 3194 [Edit]
>>3193
Oh I was reading the graph wrong, it's the usage that seems to dip about when the fps dips, the temp is nice and constant (this is much more noticeable on the first graph you posted).

The GPU Usage dip would seem to indicate a CPU-side issue to me, for some reason the cpu occasionally isn't issuing enough to keep the GPU busy, leading to the FPS dip.

Edit: Although I don't know the units of time on x-axis. If that was with vsync on and the sampling period is about 1/120 seconds, then it might just be an artifact of vsync blocking the game loop.

I guess I kinda figured it out. The solution wasn't mention or even hinted at anywhere I looked online.

I found that by switching to my second monitor and setting it as a primary, it ran perfectly. So I started messing with settings on my main monitor. I actually have three 'monitors' connected to my system. Two normal pc monitors and a TV.
Apparently it's because I had monitor 2 and 3(the TV) set to duplicate. So anything on monitor 2 would be shown on the TV. I don't know why, but once I set it to extend desktop, the issue was resolved. Changing it back, replicated the same issue. Needless to say, I won't be using the duplicate setting anymore.
>> No. 3196 [Edit]

That makes sense, trying to vsync across different monitors will create issues.

I don't know what to do anymore and I'm losing my mind. Every single fucking time I reboot my pc the audio from the speakers stops working. It's something driver related. Initially I used to just run troubleshooting but then that stopped working and I had to manually unistall and reinstall the audio drivers. I don't remember what I did and how i did it. I am also fucking tired of having to do this shit every fucking time. Is there any solution? Windows 10 pc.

I need help decompiling an android game. I'm trying to figure some stuff about the inner workings of the game, I'm no programmer but I had a few classes and hope I will be able to understand the code. What's be most beginner friendly way to go through this? I tried apktool but I only got the cli version to work, and for some reason JADX says cant make virtual machine fatal exception every time i try running the bat. What's causing this?
>> No. 3244 [Edit]
>>3243
apktool/baksmali only gets you to dalvik bytecode format, which is going to be a pain to reverse. You're probably better of decompiling to java directly, but as you noted the free decompilers are kind of poor. If jadx didn't work and you've tried tweaking things, you can try the older dex2jar + fernflower, but iirc dex2jar doesn't support newer dex versions (anything past the move to art?)

I can run it with Java 8 just fine it'd seem, but I'm on 1.8.0_372 (OpenJDK, Temurin build); 1.8.0_121 seems to be from about January 2017(?), so it's not unlikely something has changed in the meantime.

I want to self-host an imageboard, but I'm not sure what hardware would be best. Something cheap, reliable and fast(for what I'm doing) would be ideal. As far as I can tell, I have 3 options.

1. A sbc, like the "le potato" + a micro sd card + accessories
This option is the cheapest at slightly below $100, but it's the least powerful, and not so much cheaper than the other options. From what I understand, any mico sd card will be slower and less reliable than an ssd.

2. A mini PC with a mobile CPU, like beelink's. This is somewhat below $200. I'll get way more ram and storage, and a faster CPU than option 1.

3. A refurbished "mini desktop", like an hp elitedesk. This is slightly above $100. It's used though, so that's a bit of a gamble. Even though the cpu is like 8 years old now, it's still more powerful than the new mobile cpus you'll find in a cheap beelink. That's frustrating.

So yeah, what do?

If you have an old smartphone you're not using anymore but that still works, you could throw Termux on it and just use that until you have some more spare money. I don't know how secure that would be, but the handful of posts per day that you can expect from a fledgling image board shouldn't be a problem for any phone from the last 5 years or so, unless the software is very poorly programmed and uses too much RAM.

Which imageboard software are you going to use, btw?

Last night, my computer abruptly started having DHCP issues while using a wired connection(moca); over wi-fi everything is fine. Decided to wait until the next day to see if it fixes itself. It didn't, so I restarted my router and reset winsock and ip and all that on my computer. That allowed me to have an ip6 addresses, but for some reason I couldn't get an ip4 addresses. I tried every thing I could find in guides and even asked chat-gpt. Eventually, I gave up and set my ip4 address, gateway, subnetmask prefix length, etc. manually.

New to PCs. I have an ITX motherboard with ALC4080 HD Audio. The back of it has an M.2 slot, so I got to thinking I could buy an M.2 to PCIE cable, and put a soundcard on that. Problem is I have no idea whether that would improve anything.

I use mid-tier iems(Aria) and was thinking about the Sound Blaster Audigy RX. Advice on this would be much appreciated.

not a pc builder person, but aren't these both just DACs? Seems like you'd be better off using that money to buy a better speaker instead, since I highly doubt you're going to notice any difference between the two.
>> No. 3300 [Edit]
>>3299
>aren't these both just DACs
I guess? I'm not really sure. Feature-wise, I think they're distinct from products marketed as a DAC. They're also inside of your computer, which I prefer.
>buy a better speaker
By speaker, do you mean audio listening devices in general? Sure I could do that, but I'd like to know all my options for improving things.
>> No. 3301 [Edit]
As I understand it essentially is a DAC though, just built into the pc. When you plug in a headphone into your headphone jack, something needs to convert your digital PCM signal into an analogue waveform and supply voltage to drive the speakers, and that is the soundcard. I'm sure people will be eager to sell you soundcards claiming it'll improve audio quality or whatever, but I have not yet seen a compelling argument as to why it would be beneficial; and until I do I'll lump it in the audiophile snake oil category.

Pretty much the only argument I can see for a fancy sound card is if you have some special speaker setup (high impedance, or need surround sound). Maybe there's some argument to be made about fancier soundcards having better EMF shielding or something, but I'm skeptical of that unless it can be shown quantitatively .

>do you mean audio listening devices in general
Well whatever you're going to plug into your computer to listen to the audio. And if you're using headphones supposedly most of the audiophiles use an external DAC anyway as opposed to an internal way (this does have some benefit in that it's portable so you can use the same setup with your phone/laptop/whatever).

This guy seems pretty convinced. I know different sound cards can differ in fidelity at least.

edit: Looking at more reviews from all over, I'm starting to have doubts.
>The main value of this card is that between the e-mu chip and the alchemy drivers you can still get hardware 3D audio on modern systems. Testing only "does it sound good" is something you would worry about in the 90's. Today almost all consumer audio hardware is more or less perfect in that regard. This is a retro gaming card.

conversely...
>The 106db is one of the least important things about the card, yes it does have some importance (in this case, is means that the older 106db is going to usually sound a tad bit more warm/nice/fussy which is good when dealing with PC sound. But I have heard newer onboard sound with a much better DB, that sounded a lot worse!
>What happens with sound is that, when you clean it up so much be removing distortion, and still have bad/weak/small onboard parts, it just sounds like plastic, and that is okay as long as you play games and mostly only deal with sound effects, but for REAL music, you notice that it does not quite have that little bit of magic that draws you in.

>This guy seems pretty convinced.
That guy seems to not know what he is talking about, because unless I'm completely out of the water then mentioning HDMI is a non-sequitur. If you're outputting HDMI, you're transferring digital audio and hence bypassing the sound card entirely. Well I suppose a soundcard could offer a dedicated hdmi jack or whatever, but the quality of the soundcard won't matter, it's just transferring digital data.

And I have not seen any technical argument from him as to why an EMU10K1 DSP is superior to whatever bargain bin chinesium probably comes built in by default. As I understand DACs are basically a solved problem; the signal processing theory behind them is well understood [1], so there really can't be much different between them besides maybe tweaks in the FIR parameters used.

Also looking at Amazon reviews is the worst way to buy something. At least look at the hydrogenaudio forums.

I asked on an audiophile forum and got a somewhat in depth answer.
https://audiophilestyle.com/forums/topic/69096-m2-to-pcie-to-add-a-sound-card-is-there-any-benefit-over-onboard-audio/

The main thing being
>Benefits of PCIe sound card over USB audio devices
>Lower latency : It contributes competitive gaming, lower sound latency means more wins. Sound monitoring feedback for musician requires 10ms or smaller latency. I read somewhere, on some special hardware/software combination, it is possible to achieve ~1ms latency with PCIe cards.
>Multichannel output for movie watching: It is related to #1, lower latency means less prone to exhibit lip sync problems. Many PCIe sound cards have 7.1ch analog out. But more serious movie fans use HDMI and dolby atmos AV amp rather than PCIe sound card

>Modern onboard sound is sometimes surprisingly good. Still, Its amplifier has lower damping factor than better quality external sound cards, it means external sound cards provide slightly tighter bass.
>If your motherboard audio implementation is not good and/or your IEM has high sensitivity, you may hear constant hiss noise on quiet passage or, beep/buzz noise when mouse moves. Better quality external sound card provides lower hiss.

I haven't noticed any hiss, but "tighter bass" sounds pretty good. At the very least, it probably wont hurt, and based on anecdotal evidence, it does sound better. So if I have an extra $200 bucks at some point, I'll get an AE-7, since cheaping out of this makes it more likely it'll be completely pointless.

Spammers have figured out they can circumvent url blacklists by using paste sites. This wouldn't be a problem if those had spam prevention, but for some reason, that isn't the norm. The only solution I can think of is creating a list of paste sites where this isn't a problem, and informing users about it, so they wont be surprised if one they try to use is blacklisted.

This still isn't optimal since many(most) users will probably ignore any such list.

edit: another solution could be getting the contents of linked-to sites and checking those for spam.

edit2: looking at it closer, this new spam links to pastes which don't have spam links either, but telegra dot ph and bitaps dot com addresses.

My pc has been getting these insane slowdowns today. It started when I was in middle of playing some gba games on mgba. Task manager does not show anything that could account for this, only suspicious thing is this Host Service conected devices windows_abda6. I can't find anything about this abda6 windows service. This only has a very small amount of memory use and disk usage. What could be causing this?

Windows 10 has a way of slowing down itself for lulz. Never used it since I figured it out. I'd reinstall it and few months later it wouldn't be just slow, it would take nearly half an hour just to boot and then plague me fucking slideshow. I've never used a worse OS ever in my life.

I waited a bit before replying to see how the computer would perform on the following days. The slowdowns on that day persisted regardless on whether the emulator was running or not, but it was more noticeable with mgba running. Later on that day other processes related to win10, this time the usual suspects, started popping up on task manager. On the following everything returned to normal and I resumed my games. I think this may be another case of win10 fucking things up.
My CPU usage right now is around 3%-9%, sometimes higher, occasionally rising into around 18-20%. RAM usage right now is around 3,8 - 4gb out of 5,9.

Gotta say, that's a minuscule total amount. Good that it's fine now though.
>> No. 3411 [Edit]
>>3410
Linux can be easily brought down to 400-600mb of ram usage without sacrificing usability, so 6gb ram total is a lot, unless you use heavy virtual machines or heavy corporate software. That's not minuscule. It's crazy how people grew to think about ram. And it's stupid how modern software sometimes fucks you up so badly, that even with 16gb of ram you reach swap.

>>3408
Maybe, but instead of debugging bad software, it's more reasonable to try to avoid using it at all.
>> No. 3413 [Edit]
>>3409
It might have been swap usage then, which would explain the transient period of slowness. I like to log cpu and memory usage so that such transient issues are easy to diagnose.

>>3411
It's a lot in absolute terms with a lightweight OS, but for something modern and bloated like win10, 16GB is really the minimum. And then add on top of it modern browsers/frameworks which assume memory is endless.

I want to get an external HD. Which brand do you guys use and/or recommend? I looked onto Seagate first, but apparently there's some sketchy shit going on with them, with some reports saying it's the worst brand. Toshiba looks nice and at least where I live it seems much cheaper than Western Digital. But I heard the control board is directly built on the HDD itself and if the USB port develops any issues it's over.
