Not necessarily . Blizzard made changes to graphics and Nvidia have had to develop new drivers specifically for the Blizz changes, Nvidia dont roll out new drivers just for the sake of it, they have to when publishers change their games.
Problems with most of Blizz changes they lose what they’ve done, so instead everything just gets Band aid fixes and then continue to add more band aids on top of the previous ones to hopefully fix an issue instead of actually doing a proper job and then informing company’s like Nvidia of the exact changes.
If Nvidia knew the exact changes Blizz had made it would be a easy driver fix for them , but they don’t, tbh I don’t even think Blizz knows themselves what’s causing the conflict with drivers.
Lets be honest here there has been so many issues with every aspect of the game since Shadowlands launched far far more than any other expansion has ever had, Blizz have openly admitted they had to cut a lot or corners just to get the game “playable” for the already delayed launch and admitted many aspects were still under development, Shadowlands launch was basically an Alpha and still is.
Blizz currently are in a catch up mode, they are rushing around trying to fix everything and also still trying to make content for future patch’s, tldr: everything is a mess and Blizz are falling behind every patch
