[quote="nipzor"]just tell me step by step how to check such stuff and i tell you how it turns out, remember that i'm very new to this linux stuff[/quote] 1. open a command line and type: glxgears -> post one result line (should look like this "26820 frames in 5.0 seconds = 5364.000 FPS") 2. open a command line and type: fglrxinfo -> post the output (I don't know if this works, but if not please say it) 3. Could you say which chip your GPU has? (9200,9800,X800,X1600,X2600, ...)
