Im using a Radeon x1050 with ati's drivers, no problems in most games.
The game im writing on is a topdown shooter.
Doesnt use any graphics that SHOULD be heavy to render, only thing i can come to think about is a png image, 800x600, thats rendered every frame.. But that shouldnt be so bad?
The FPS in this game is dropping from 75(1000fps without vsync) to 37 fps :S
Here is the sourcecode to the whole game, i know its not that optimally coded, but i started writing on this just a few hours ago.
