980Ti to 7800XT upgrade microstutters

[maartendc]

Hello all,

 

I recently upgraded my dying GTX 980ti to a reference Radeon 7800XT. (rest of system: Ryzen 2700X, 32GB 3200MHZ DDR4, B450 mobo)

 

EDIT: I guess I should also mention that my PSU is only 600 Watts (Corsair 600W Gold rated SFX). This is below the recommended minimum PSU for the 7800XT of 700Watts. Could a lack of power to the GPU be causing this? (the GPU power draw shown by Radeon overlay is never above 250 Watts).

 

Obviously the performance difference is massive, and most games run really well on ultra at 1440p.

 

However, in Battlefield V, I am noticing some microstutters that weren't there before. With my 980ti, I was able to run Battlefield V on high / ultra, and it was super smooth. With the 7800XT, I get microstutters down to 19fps (99% percentile). Is this normal? Is this because of the AMD drivers? Or is something else going on?

 

I could upgrade my CPU to a 5700X3D, in the hopes that fixes it,  but I am kind of annoyed this problem has popped up with a much more powerful GPU.

 

Anyone have any recommendations on this? Thanks!

cpu is choking the gpu. 5600(x) or above if your motherboard supports it.

Probably CPU bottleneck, try limit your FPS to slightly below average. 

Do you actually able to get 3200mhz with that Zen+?

Did you ever uninstall your old GPU drivers? 

[WereCat]

Have you removed the old drivers with DDU?

I know the CPU is the bottleneck in this system, but does it make sense that the performance is actually WORSE than with my old GPU? To me, the CPU performance should have stayed the same.

 

At Vsync 60fps mode, I cannot imagine why my CPU is all of a sudden causing microstutters, whereas before, it was not.

 

Also, yes, the RAM is running at 3200 Mhz with the XMP profile.

Yup I did. Thanks.

Yes I did, thanks.

LTT forums users when they see a possible solution to a troubleshooting problem.

You are right and correct, this is odd, this isnt a situation like ADA has, the 2700x while yes will bottleneck should NOT be causing this issue. 

This is not normal. 

I'm saying this more to preempt other users from just saying that it is and telling you to money cannon the problem, rather then finding the problem or giving you an actual solution.

I would say because the 980ti is not waiting from instructions from the cpu as much as the 7800xt is. i think the problem would be worse at 1080p

What is the CPU and GPU usage when the dips in fps happen?

Yes it can if CPU is the limiting factor in which case FPS cap should help. 

[xAcid9]

Or maybe the game/gpu still compiling shaders on the fly hence the stutters. You're on DX12 yeah?

When the underutilized GPU drops to lower power states you get those stutters. A new CPU (or platform) would decrease those significantly.

[ARandomPerson]

    Press Alt + R to open the Radeon app. Then, navigate to the global settings and turn on Radeon Chill if and only if the stutters are due to a CPU bottleneck. Mess with the limit till the stutters are no more

It happens both on DX12 and DX11 (Battlefield V supports both), but it seems to be worse on DX12.

Yes, but I am running in 60Hz Vsync, so the FPS cap is 60fps, Its not like Im running at 200 fps and then the CPU all of a sudden is hickuping, it should be a smooth 60 fps, which the CPU is capable of.

I'm not sure, Ill need to check that.

Thanks for the feedback. My gut feeling was also that this is not normal.

I guess I will try and reinstall Windows, see if that helps more than the DDU did.

Hmm, interesting, that is a plausible explanation. Would a different power profile help in that case?

 

 

I guess I should also mention that my PSU is only 600 Watts (Corsair 600W Gold rated SFX). This is below the recommended minimum PSU for the 7800XT of 700Watts. Could a lack of power to the GPU be causing this? (the GPU power draw shown by Radeon overlay is never above 250 Watts).

No. Disabling the Ultra Low Power State would help a tiny bit. Only a CPU upgrade would truly help.

If there was more power needed than what could be provided, the PSU would trip. All cables are plugged in right??

I mean your total wattage is ~500 (estimation based off of cpu and gpu out of my non-existant brain, so excuse me) (if your really stressing it). I don't think psu is the issue but your certainly living life on the edge. Although if your psu was overloaded you would know, as your system would either just shut down, or would blue screen.

Yeah thats what I thought as well, if the PSU was overloaded, the system would just shut down or crash...  Yes for sure the GPU cables I triple checked they are plugged in.

[Jeppes]

That gpu does over 200fps in BFV 1440p. If you cap it to 60fps, it most likely drops down to some crazy power saving mode that could cause issues. Try supersampling it to 150-200% res scale.

Okay so a little update on this...

 

I played Battlefield V again last night, and the microstuttering issue was mostly gone. Looking at the frametime graph of MSI afterburner, it basically looked the same as with my old GPU. Mostly smooth 60fps, with very rarely a stutter.

 

Is it possible that the constant stutters were due to shader cache compilation? I've read that this needs to happen after installing new GPU?

 

Switching maps, the issue was there again briefly, and then gone again. I've heard it needs to compile shaders for every map, so that would check out?

 

Not sure why Battlefield V would suffer from this issue, but I have not noticed it with other games at all? Do some games not compile shaders? I've not really heard about this phenomenon before..

 

Thanks!

Shader compilation stutter is a very common issue in most new games. I don't remember this being talked about in regards to Battlefield V and I have never played that game so can't comment on that in particular.

Some games will compile shaders before you launch them, other do it as you play. Every time you change GPU or just drivers the shaders will need to recompile.

I thought that was a UE5 issue, Doesn't Battlefield use Frostbite?

It's not just an UE5 issue. It's more like a DX12 and Vulkan issue and the way devs decide to implement it.
