I'm having some weird bug in X34. Watching some cars on the redline racing server, their tyres are smoking all the time as if they'd have a leaking engine.
The old versions don't use hardware vertex shading. So with car reflections enabled, you will get much lower FPS compared to S2, because the CPU has to do more geometry calculations.
You can't steer when you're stationary. While riding you can steer to help keeping the bike upright. When you're riding faster you don't have to steer that far (or quick) to get the same effect, so it's easier.
I think what he means is, that there is probably more clutch wear if you engage it for a longer time instead of putting the gear to neutral, e.g. if standing in front of a traffic light. Maybe I'm uninformed as well, but that's what I was told in driving school.
If a user doesn't want to use the automatic skin download, he will get an error message for every single skin when he enters a server, that's quite annoying. So my suggestion is to remove the skin not found messages. There is no use for them because you can already see that there is no skins if a car is white.
