Experiencing stutters since around late October

[Mushroom]

Hello, haven't been playing the last month or so been kinda burnt out but hop on every now and then to mess around. Hoping someone can help me

Around the beginning of last month, I reinstalled Windows because my installation was getting old and I have always seen it as good practice to get a fresh install every few years especially with W10 EOL I figured it was a better time than any, however since then I have been experiencing severe lag spikes which have made me not want to play they just dont seem to go away I have tried multiple things to fix it such as

- Another fresh install of W11
- Fresh install W10
- Different SSDs
- Making sure my drivers are all up to date and installed.
- LTSC versions of Windows (nerd shit)
- Secure boot in BIOS (not that it would make a difference), checking ram speeds

This seems to happen only in GMOD, I will run some more tests later maybe even put some videos here but I am at a loss. I would like to play again but this is just kinda retarded, I use linux most of the time, kinda just use windows for college and GMOD. Game runs perfect in linux suprisingly just cant be arsed playing on linux because of no raw input so game feels like shit.

Pc Specs
Cpu - Amd Ryzen 9 9900x
Gpu - Amd Radeon 9070xt
Ram - 32GB DDR5 6000mhz
No point in putting my drive in here, problem persists across basically everything I have tested with

Thanks!

Does this issue occur in other GMOD gamemodes?

Yep, and CAD software I use.

I ended up just swapping back to my NVIDIA GPU for now, it appears to be a Driver issue? Something about amd DXNAVI and shader caching?

I'm glad you've got a solution - drivers drive me up the wall, pun intended. I used to have this issue ages ago in like 2014, ended up being hardware that just didn't handle together well, and also an extremely slow HDD

Its such a shame today when stuff is released we are basically the beta testers, 800 euro on a GPU that works PERFECTLY FINE on linux but on windows they bundle a bunch of stupid "optimizations" THAT MAKES IT NOT WORK

You'd think hundreds of billions of revenue would result in software that doesn't require workarounds wouldn't you lmao

If you wanna switch back, you can try a couple things, like turning off Hardware-accelerated GPU scheduling (System -> Display -> Graphics -> Default graphics settings)
and also Game Mode which is another windows "optimization" (Gaming -> Game Mode)

Did you make sure to do a full clean and wipe of and old GPU and driver files when you installed the AMD GPU? First time I hear it causing stutter for Gmod.

E: seeing as you did fresh installs of Windows this post is most likely useless but you never know

Are XMP and Rezisable BAR enabled in your BIOS?

I enabled Resizable BAR and found it got worse and my FPS was half what it was previously, I will be testing more over next few days so ill give XMP a shot

Did you try any of the solutions and suggestions in the reddit thread as well? I'm not familiar with AMD and it's quirks at all but it seems to be a common issue. If you did, i'll suggest you some benchmarking tools that can further help diagnose the cause of your issue.

Completely fresh install multiple times

What benchmarking tools do you suggest?

What benchmarking tools do you suggest?

Latencymon & CapframeX/Presentmon (CapframeX uses this). This is going to be a long and painstaking proces involving a lot of manual testing but you're going to want to test and record a few minutes of gameplay or tasks where you are encountering spikes.

At some point you're going to notice a spike and whetever happens at that point could indicate what is going on. Frametimes will help you with this. If you're, for example, encountering a lag spike during asset streaming or entering a loading zone, this could be an indication of the cause. Looking at your clip this is very possible and could indicate a storage issue but honestly might as well be a graphics issue if, for example, you are entering a cubemap. I have not decompiled the new v6 yet to give you any certainty on the locations where you are encounting a stutter.

Monitoring everything will help. IO throughput, temperatures. And i mean every temperature. from CPU to SSD. Run SMART tests on your drives and ensure ANY and ALL external factors are DISABLED during your testing. This means getting rid of Discord, Teamspeak, the NVIDIA/AMD overlay. Disable all unessesary apps in your startup settings and Startup folder. Whenever you reboot your PC, open task manager and ensure any non-essential apps are NOT running.

It's not easy to point you in a direction where to start but there are loads of threads on tomshardware.com regarding these issues and I've come to notice ChatGPT actually provides helpful information regarding these issues because it's so common.
