Hi Everybody!
For those with AMD / Asus motherboard issues, we finally got an internal repro when we saw that some players needed to uninstall AI Suite III. So we installed that software, went into a live game, no perf issues. Then we turned on HPET and BAM, the FPS cut in half which is what a lot of players saw. Turning off HPET fixed the performance issues so both need to be present to cause this weird degradation. It is apparently really hard to uninstall AI Suite III so I don't have any recommendations for removing this software and I don't suggest installing it just for kicks.
You can turn off HPET by using the following steps:
Step 1: Open the windows search bar and type “cmd”
Step 2: Right-click the Command Prompt app and select “Run As
Administrator” (access will be denied if not set to administrator)
Step 3: Enter: bcdedit.exe /set useplatformclock false
Step 4: Restart computer for this to take effect
