In games like WoW while the higher VRAM definitely helps, just having a GPU which cannot run normally with direct X12 is just unacceptable. I'm having massive blackouts and I tried everything on 7900 XTX. The card works fine with almost every other game, but I play mostly WoW and Im screwed along with thousands of other players who chose AMD over Nvidia. "Can Nvidia get away with it" yes they can. As long as their drivers are working better with most games, players like me will choose Nvidia next time. Heck I was even considering selling my 7900 xtx and getting a 4080 super.
