I don't know about GRX, but I suggest you take a look at ALLEGRO (on   
X2FTP). This is a graphics/sound/keyboard/joystich/mouse/timer library   
built for game programming with well optimized blitting routines!. I get   
speeds of 200-300 FPS in 320x200x256 (on a 486 DX4-100) doing something   
similar. (just clearing->blitting)
