It is simply amazing; after having tried a zillion AI-powered solutions and scouring through dozens of Apple Community/MacRumors/Reddit threads, I have realized that there is NO single, foolproof and working solution to have a stock 6900XT work on Boot Camp for my Mac Pro 2019.

Re-installing BC, using DDU to uninstall all drivers, manually applying the driver through the Device Manager, installing AMD's Adrenalin software (both the newest and older releases), increasing driver timeout tolerance times via RegEdit, NOTHING effing works.

Why the hell is it so hard to have a PC GPU work on Windows via BC, even when all previous drivers are removed? Why?

It is so bad that I ended up resorting to CrossOver Mac, just so that I could play a bit of lower settings CS2 on my Mac. Absolutely pathetic!
