   opengl very slow? just 4 frame/s
  I just draw a textured rectangle and a textured sphereit becomes very slow just about 4 frames per second even in the full screen mode?it opengl really so slow or my computer that matters?my display card is Geforce MX 440,i'm writing a mini-game in 3D, but if opengl's really so slow, should i switch to using directx?thank you.   
  You must be doing something wrong. Have you the latest drivers? Do you want to  post your code? Are you uploading textures every frame? Something, possibly someting simple, must be wrong.   ;  Sounds like software rendering, do you have the latest driver from nvidia.com?   ;  problem solved after updating display driver,thanks every body
