ROFL!!!
to funny...
to answer one question, yes your frame rate is determined via your GPU but also the game itself..
ETQW was designed (using the IDtech4 engine) to run smoothly at 30fps..
not that is matters, TBH- the netcode for this game has been and will always be junk..
you can set your FPS to 300 and still experience horrible performance due to lag, not FPS..
