Issue with AMD RX 6600 series GPUs in games with low GPU usage and high CPU usage

I've encountered a recurring issue with my AMD RX 6600 series graphics card while playing certain games like Valorant, CS:GO, and League of Legends. During gameplay, I've noticed significant performance drops, including FPS reductions and lag.

The problem seems to occur when my GPU detects low usage levels while my CPU is under heavy load. As a result, the graphics card drastically reduces its clock speeds, leading to performance degradation. This is particularly frustrating as competitive gamers, including myself, often set graphics settings to the minimum to maximize FPS. However, this action seems to exacerbate the issue, as the GPU interprets this low usage and lowers its clock speeds, causing the problem.

It appears that the root cause lies in how the GPU interprets low demand scenarios, mistakenly reducing clock speeds to as low as 100 MHz. This happens even in situations where maintaining maximum GPU performance is essential for smooth gameplay.

This issue has a significant impact on my gaming experience, especially in competitive environments where quick and consistent responsiveness is crucial. I believe addressing this concern promptly is necessary to ensure an optimized gaming experience for users of AMD RX 6600 series graphics cards like myself.

I appreciate your attention to this matter and hope for a resolution that improves gameplay performance for affected users.

So when will the fps drops stop and when will we be able to play normally again?

Hello???? Anybody???  OP figured it out perfectly, I can see the clock speeds of my GPU go down while trying to play Valorant on low settings. I tab into Chrome, I see 98% usage. In game, I see 34%. That's crazy!

Are u using any kind of things such as chill or frame limiters ?

If the GPU is indicating low utilization because the game settings are purposefully set low, and the CPU is showing high utilization, then the system is being bottlenecked by the CPU, not because the GPU is reducing clock speed.

You can try using a GPU Tuning Profile such as "Rage" if you want to force the GPU to run at a more aggressive level. But if the game frametime is being buffered by CPU-busy there's little for the GPU to do.
