yeah, real men use mice!
there's some unbelievabley fast mouse drivers out there (NOS PBU I'm looking at you
) and it's perfectly possible to enjoy lfs with a mouse. Of course, you're at a slight disadvantage because of the digital accelerate/brake but you can still put in respectable times.
You have to set up your brake force for the 'worst' corner of the track. So for example, when you're taking a tight corner after a fast downhill piece of track, your max brake force mustn't lock the wheels. But that means on other easier corners you won't be using as much brake force as you might otherwize be able to, so you have to brake a little earlier.
And some corners are harder for mousers than others because of digital brakes (damn corner on fern bay that's real bouncy on the lead up is tough because you can't brake smoothly on it).
And RW cars are harder to drive with the mouse that FW cars, which might limit what you can drive competitively and safely.
And also, whilst 5-10 lap races are ok for mousers, with longer races (and certainly with more powerful cars) your tyres will wear faster than those who can be gentle with their braking.
I stick with the lower-power FW cars myself, but you can still have great fun, great races and it's always nice to spank wheelers
btw: I use left mouse for accelerate, right for brake, and S and D for changing gears (auto-clutch).
