Did a minor upgrade to an RX 6600 from a GTX 1070.
Playing Apex Legends and Valorant, games stutter. Every copy seconds it loses frames.
Some say "It's building the shader cache." Maybe. It does start off really bad, every match... But then it never goes away completely.
Framerate is high. Temperatures are normal (60°C). Usage is under control, no bottleneck. Some games run normal, but it seems the multiplayer games I need to run smoothly, stutter the most.
Valorant is the easiest to test with because they have a feature stat graph called "CPU Wait GPU Time" ...The it seems to be on the GPU. The CPU is waiting on the GPU to provide the next frames. Example = https://i.imgur.com/1pZOim1.jpg (This was a single opponent engagement. Stutter stutter stutter. You can't play Valorant like that.)
I think I've tried everything I've read online. Nothing has had any impact.
Ran DDU and reinstalled the latest Catalyst Software.
Ran DDU and reinstalled the drivers only.
Reinstalled Windows 10. (+Repair Windows SFC/DISM)
Unplugged all USBs expect M+KB. Disabled all startup software.
Everything in this PC is running cool. Maybe 60°C max for both CPU and GPU.
Regedit to turn Shader Cache = On.
OC 7700K to 4.8Ghz. (5.0Ghz was requiring to much voltage compared to 4.8, so I'd rather not)
Disabling DXNavi
Different drivers. Latest drivers, February, November...
No change, after no change.
Really, the only thing I can still think of it upgrade my RAM to something faster. 3600 Mhz. But I've read plenty of people with faster RAM also get stutters. So I don't think that's it. I believe it's software related, because some demanding games work smoothly.
