19/11/2022 Edit: Re-pasting thermal paste on GPU fixed the issue.
Basically title, other than that clock speeds are completely fine. I just found out this yesterday and don't know when it was started. I think it wasn't like this 4 or 5 days ago. Yesterday I booted up Cyberpunk 2077, clock speeds were completely fine in the menus, but after it loaded to open-world GPU clock went down, thinking it was badly optimized, started HZD and it was the same, RDR2 it was the same, as soon as GPU utilization goes to 99%, clock speed is going down to 900-1100Mhz. I noticed in RDR2 that CPU Utilization never exceeds 5%. I have tried multiple GPU drivers using DDU, rolled back Windows 11 recent updates, rolled back the recent AMD chipset driver, and finally formatted the PC but still, nothing fixed. If it's hardware related how can I make sure what is faulty? Everything seems working normal.

I have an R5 2600 @3.85 GHz - RTX 2070 Super - 16 GB 3200Mhz Ram, TUF B450 Pro Gaming Motherboard.
BIOS, GPU, AMD Chipset's all is up-to-date. Even tried to "Load Optimized Defaults" in BIOS, OC'ed the CPU but still nothing. I did a CPU stress test it seems working as usual. Everything seems working as it should but as soon as gaming starts I am having this problem. Hope you can pinpoint me to the right direction, I am out of ideas.

No idea why Render Latency are that high.
