I seem to be doing something wrong.... I tried to make a very efficient tile system but when i check the framerate it''s like 33 FPS windowed 640x480 and 8(!!!) on fullscreen 1024x768. I also tried to make a little app that just blits 1 640x480 image on the screen each frame and i''ve been getting the same results from this. I''m not using any special flags with this result, but i tried settings/combining all of them. I''m using windows XP with a Gforce2 and the few high-end games i play all run smooth. The surface is 16 bit but setting it to 8 doesn''t really help me much. Please tell me what i''m forgetting.... thnx!

You must make sure you convert any surfaces you want to blit to the screen to the screens format (does that make sense? )

SDL_Surface* my_surf = SDL_LoadBMP("blah");

my_surf = SDL_ConvertSurface(my_surf,screen->format);

Or something similar. There are also things you can do with the vid mode flags, like not having a HW surface necessarily etc.
