Maybe I should avoid nVidia if I want to do anything 2D in Blitz?
Well unless you're going to tell everyone who plays your game what videocards they should buy and avoid, I'd probably be more inclined to either :
(a) Avoid 2d if I want to do anything with Blitz on Nvidia.
or
(b) Avoid Blitz if I want to do anything with 2d on Nvidia.
