Kiwisimracing 2 had same issues with L2R as the KSR 1.
Driver swop would be done and as new driver is to accelerate out, game hangs. Have same sluggish keyboard problems with L2R running.
Tyres didn't last at all on the escort, think i made lap 8 when i spun and put it in to the wall with fatal damage. Race Over. At that time tyres were pretty well done with still more than half a tank of fuel left.
Found no lag on server or cars ghosting around.
Everyone seemed to know there way around a track, Little dallara fiats and europa's are very fast through corners.
Overall happy with performance in testing, improved lap time with a full tank of fuel.
Cheers
