According to 1Up, both the PS3 and Xbox 360 versions will run at 30 frames per second, and they look mostly identical to one another. Granted, the PS3 version of GTAIV is a touch behind in the development phase - which we already knew - but it will still launch at the same time as the 360 edition. Now, 30 fps may be unacceptable in the current world of first-person shooters, but if it's steady, it should work out just fine for GTAIV.
