Update! I tried the TdrDelay trick and rebooted and then cleared both shader caches (clearing the radeon driver’s cache probably isn’t necessary, but it’s just a single click).
I’m now playing Congquing at 1440p @ 120+fps with all settings on high/ultra and anti-lag and enhanced sync enabled in the driver control panel.
From the reddit thread:
Simply go to: Start → Run → Type in “Regedit” and navigate to:
“Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers”
Create a key of type "DWORD (32-bit) for a 32-bit system. or a "QWORD (64-bit) for a 64-bit system.
Name it “TdrDelay” with a value of ‘10’ as “Decimal value”.
Reboot your system, launch the game, and the crashes won’t happen
It only took all weekend to figure it out… Best of luck to anyone still dealing with this
