That's a horrible way at looking at it. You cannot enter "who's got the better computer" into a competition of skill in MTA. It just makes it completly unfair if you can move faster than the person you are against. The standard of 30fps i think is fair with there being no need for it to be any higher, and i would never turn my FL off just for a cheap advantage over someone, doesn't feel like you're actually winning at all.
Fully agree with chode
It's all about fair play , some ppl just dont care about it and they will do everything to win. That's sad, but it's true
