how to setup parallels & XP to speed up Graphic Power

Hei

as long as I use Parallels with every Version it got more usable and Powerfull!
Thanks to the Devloper Team!

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?

2. Perform Mac and Windows side disk defragmentation http://www.xvsxp.com/system/system_tools_defrag.php
3. Set Adjust memory limit from Auto to Manual at Parallels Desktop -Preferences-Memory, and set limit a bit more higher than VM memory
4. Disable Themes in Windows XP serives.msc stop Themes service
5. If you are running in Coherence, try to switch to Single Window, or lower Mac resolution
6. Some antivirus software can load CPU when Heuristic Prediction is set, or Tamper protection (Symantec, MacAffey), adjust settings to risk you are supposed, high security settings is not always good idea, as it can also affect software running
7. Run msconfig , and disable unneeded startup items

8. Make sure that no VNC,or remote desktop connection is established to Mac, this can slowdown Parallels Desktop
