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!

980Ti to 7800XT upgrade microstutters

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

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

Strangely, I also had some initial stutters on the DX11 mode of the game, although much less severe than on DX12 mode (game gives you the option to switch).

In any case, the problem seems to have subsided without me changing anything.. most logical explanation I guess is that it was some kind of shader compilation stutter.

I also did some further checks on the GPU:

- 3D Mark Time Spy graphics score is normal for a 7800XT (18920 points)

- clocks seem stable

- temps seem normal (not exceeding 80C)

- games seem to run fine now

So I guess it is behaving normally now
