Has anyone tried reinstalling or rolling back their Nvidia driver? I reverted back to 527.56 and Valheim runs great again with proper cpu usage and gpu usage is no longer stuck at 100%

Every setting is at max with motion blur off @ resolution of 5760 x 1080. I was getting 18 fps in the game menu, where before it maxxed at 60 fps. In game was getting a struggling 18-42 fps. I noticed my 13900K was showing 1-2% usage before with my 3080 running at 100%

Now, after installing an older driver, my cpu usage is around 6-8% and my gpu usage is 8-14%. My frame rate is back up to 84-142 fps. I even run 51 mods because base game is a grind fest.

I just tested this on my other gaming pc with a 3080 and the results were very similar. That pc is a 6700K with a 3080. Resolution is 1920 x 1080 and getting around 130-145 fps in game.

Just putting some information out there if it can help someone else get the game running good again.
