Increased FPS greatly increases ability to push vehicles. Watch the video for comression 20 fps vs 90. I believe 200 fps will allow you to run through vehicles like they don't even exist. So basicly you are suggesting to legitimate a hack.
There is another benefit - with high FPS when moving, you can change move direction quite a bit faster which gives advantage in PVP. SAMP is greatly very much dependent on FPS, many other things changes when FPS increases.
