RX6000 RDNA2 Issues With Unstable FPS In Many Games

[LoadsaMoney]

And with such games, we mean titles that need to push extremely high framerates; the result is visible frame drops. A substantial number of RX 6000 graphics card owners seem to acknowledge the problem.

Over at AMD's Community support page, a thread is filled with reports on frame drops in games like Rocket League, Fortnite, and Counter-Strike: Global Offensive. CPU-intensive games like CS: GO, according to Redditor Tricolor3s, for example, would show abnormally large drops. His RX 6700 XT would perform less well than the Vega 56 (which he owned before) in such a situation. For example, CS: GO shows drops from 400 to 150 with the 6700 XT, Fortnite records a drop from 400 to 50 fps. The cards' clock speeds would go up and down sharply, which see looks to be the root cause. AMD is aware of the issue and is looking into this. Thus far, a precise cause has not been fed back, but a solution is being sought.

So what I'm getting at, is that the GPU having to ramp up to a high power state from a game that usually makes the GPU have a low power state and that causes the frame drops. No idea why the latest AMD drivers didn't fix this. This seems to be purely an AMD driver issue, and one that should be easily solvable.

My FPS double when I paired my 6800XT with a Ryzen 5000 series CPU and keeping the voltage at 950mV for my overclock helped stabilize it.

only been playing Warzone and thats been pretty stable fps wise on my rx6700

Have been having some issues with fallout 4 and my card, but i cannot say its not due to modding in all fairness.

Looks like a driver issue causing the RDNA2 GPU to keep switching between 3d and 2d clocks while gaming in scenarios that are CPU bottlenecked.

What's probably happening is the GPU gets sick of waiting for the CPU to play catch up and decides it wants to go back into idle mode, as soon as it goes to idle the GPu becomes the bottleneck so it comes alive to full power again - then rinse and repeat.

Until AMD finds a fix, the only way to avoid that is to make the GPU the bottleneck, i.e play at 4k instead of 1080p then you won't have performance drops.


It's not a new issue, due to low supply the volume of complaints is low, but people have reported this issue a few months ago and AMD has yet to fix it

Hmmm no probs with world of warships or horizon zero dawn.

No issues with my 6800xt but I don't have the latest Windows 10 update that at the moment is known to be breaking games for amd and Nvidia users.

I expect that a lot of game issues at the moment is related to that update.

off the top of my head I don't recall either of those being cpu bottlenecked games
