It's definitely not the 9600GT being a problem, when I first bought Ego Draconis I had a 9600GT and after I updated the game to version 1.03 everything ran fine. I've since bought a GTX 460 but it did run fine on the 9600GT 1GB edition. I did notice that you have 60Hz screen refresh, can you change that, or is there an option for vsync in ego draconis? I can't recall, but disabling vsync might help if it's enabled.
