Sorry, I don't know how you can't disable it, but I DO know some fun facts:
The higher the framerate, the heavier and slower your car/boat will get, the bigger your turns get when driving in a car, the the harder it becomes to take off with your skimmer, the faster your rotor blades spin up with any helicopter, the faster you'll see the clouds move, the heavier the rain will fall down, the faster the rate gets of NPC's in car's pressing thier horns, the faster NPC's will cut what they where saying in the middle of thier sentence, the faster rockets will travel , the water textures move, AND or course the more often your game crashes.
The physics in older GTA's are build to peform the most natural at 30FPS, which is a shame. When I was still busy completing the game I would turn framelimiter on in any vehicle exept for helicopters for optimal driving peformance, and I would play on 90FPS when I was on foot, the game would often crash on a framerate higher than that, and all that with RTSS running or my game will not run at all with framelimiter off.
For GTA III I would play on 30FPS constantly because either the game would crash or Claude would be send flying when walking downhill.
