I think I have found a fix. I Have an ASUS B650-E Motherboard, updated the "ArmouryCrate" and used that to update the BIOS as well as downloading ASUS "DriverHub" and that had a new driver for the chipset. Also set the BIOS into "Performance" mode also turned on the "GameMode" in advanced settings.. so far game works well again..

Also noting I have 24H2 version of windows 11. Really need a fix here. Not sure how more people don't report this issue because this processor is probably one of the most prevalent in gaming... Maybe they were smart enough to not use windows 11, ugh i hate it so much. Honestly about to find a copy of windows 10 so i can game in peace.

Brand new PC with a 7800x3d, 32gb ram, 5070 Ti card and I am having this same problem. Game becomes absolutely unplayable after 20 minutes or so.
