I have been playing WoW Classic just fine on a late 2013 MBP with 750M gpu until I upgraded to Catalina a few days ago. Now in game there is a wicked delay when trying to move the camera with the mouse. Others have suggested turning off auto GPU switching which does solve the input lag, but then it causes weird texture artifacts on the map, water, and on some textures in the world. I might be able to play around these while i wait for a fix but the map at the flight master is garbled and it’s impossible to pick a fight point : (
Has anyone else experienced anything similar?
