Since Version 3 I can really use me modelflying simulator ( reflex-sim.de/ ) and now it mostly work nice! But after a time of work the simulator gots "cog / stuttering" in the simulation graphic. I tried optimise XP for Applikation Power, give Parallels 768MB RAM and 64MB Video memory, performance for VM with hight acceleration, enable VT-x Support, ... I changed/Switched this setting on and off but I got not away the problem - a better Performace I could reach ... The Graphic Power of my iMAc DUal Core 2GHz with 1.5GB Ram and a ATY,RadeonX1600 with 128MB VRAM should Ok - I think. Any suggestion what could be done to got some more Power to the Graphic?
