i am using 2.2 for stability reasons (2.1 was a disaster on my sytems). As you mentioned the tesselation tools were good improvement in 2.0. As were the faster redraw speed, though 2.2 seems a bit slower than 2.1... I prefer to have stability over speed any day (waving to Couerl as i zoom past his burning wreckage on the race track
