[soratheultima]

so my gamestop suprisingly had super mario galaxy 2 so i bought it and im so excited to play it i don't wanna use open gl because it is slower...
so all what i get is a black screen with perfect sound. i tried open gl and it works but of course the frame rate is slower

specs :
AMD Phenom II X4 940 Processor 3.0GHz
4096MB ddr2 RAM
NVIDIA GeForce 9800 GT
1000 MB

(using wiimote through bluetooth)
