STALKER 2 performance issues after upgrading PC

[Ceranoe]

I upgraded my PC quite heavily after some really choppy performance since my CPU was quite dated. I am currently running a Ryzen 7 9700X, 32 Gigs of ddr5 ram, RTX3070 TI and the game is running on an M.2 drive. I get better overall performance now, averaging around 60 frames on medium, but I still get some serious drops especially during combat and when I entered Pripyat my frame rate dropped to almost 20. Is this an issue with the game or is there something I havent done to improve my gameplay?

Resolution and etc ur 3070 ti has a limiting factor of vram

[Ceranoe]

So the recommended specs are a incorrect? Thats rough. For the record, im playing on medium at 1080p

did you enabled XMP or AMD EXPO in bios?? if not. thats the first thing i would do.
also did u install the correct chipset driver?
did you update the bios?


update bios version to the newest.
after that
go bios enable amd expo so your ram works correct. (or xmp)
go windows power option and set to maximum power.
install correct chipset driver.

Unfortunately your 3070Ti doesn't officially support DLSS and frame generation, which can dramatically boost your framerate, but you should still be able to use the AMD equivalent, called FSR 3.0, even though it's an Nvidia GPU.

Look for that option in the game's settings and enable it.

1080p ok and just medium yea not that bad for 8gb then. do u have upscaling off? Im guessing you also installed the AMD chipset drivers off the AMD website? But yea bios updated to newest would be a good idea i second that recommendation.

I appreciate the tips. Ive gone ahead and ordered a new AMD RX 9700XT. I might as well go full AMD this round. Hopefully this stabilizes the game for me.

I know dudes who have 4090 cards and with top shelf cpu's, still getting choppy, unstable fps. The game is unoptimized sorry to say. Don't get me wrong, the game isn't unplayable, it plays smooth in most areas when going on missions, but quite a few areas that are occupied with AI players... the game becomes very unstable.

Patches are coming, but... probably going to take a lot of time to polish this rough release.

Correct, and I am one of them, but it's rare so far. I've only see it start to happen once I get back to the Slag Heap, and this can be after a good 30-minute long mission. A quick restart of the game completely fixes it and I'm lucky that the shader compilation only takes about 10-15 seconds for me each time.

I have yet to get much further into the game, however. I dread reaching the larger settlements.

I will note that after upgrading my CPU to the one I listed, my framerate in large settlements like Rostok stopped tanking. Combat is still dragging my frames down, so I am hoping the new graphics card reduces some of that.

I upgraded from my 3080 12gb to 7900xt and it fixed all my FPS issues overall which I didn't expect

It's not your PC. It is the game.

so stability problems with crashes and sometimes also with crashes of the entire OS... you should not necessarily activate xmp or epos and also use softer timings. because these profiles do not have to run stable and can cause problems and can also behave differently depending on the uefi version... you should also do without OC of the CPU and GPU in favor of stability.

8GB vram is simply far too outdated for 2025 and that was already the case last year and the year before last.... 8GB was already a minimum for me when the amd rx480 was released, which is a crisp 8 years in the past.

Since stalker 2 is still too unstable for many, your suggestion would probably even be counterproductive for most people and would make it worse.

@OP already flashed newest uefi and installed newest drivers etc?

the game also runs sadly with dx12 and i can't think of any ordinarily optimized game because MS dx12 was just quickly thrown in after the new version was announced by opengl and vulkan. before that it was said that dx11 would be the last... and dx12 is still the last garbage but needed for RT.

so performance nvidia < - > amd... the game uses features mainly from nvidia... remember earlier days where it was the same and then with the amd system e.g. simply no fog was displayed while with nvidia gpu's you had dynamic fog ( e.g. first metro title ).
do nvidia and amd systems have the same display and features in stalker 2 or is there a difference?

You installed everything from zero, or did you upgrade with the same windows installation???

On the same end of that stick too unfortunately.
