I just upgraded to Parallels 4 because it supports directx 9c however I am having problems running Microstation V8 XM in a Windows XP Pro VM. The screen gets scrambled up and blanks out in areas within the software after it loads. The only way I have found to allow the software to function somewhat properly is to notch down the hardware acceleration slider (located under Windows XP display properties -> settings tab -> advanced -> troubleshoot tab) disabling all directdraw and direct3d accelerations. Unfortunately when I do this I also get mouse pointer artifacts from the mac side showing in the middle of the VM screen, and other functions like expose stop working if trying to invoke from within the VM. I am using a 2.6GHz Core 2 Duo 17" Macbook pro, Invidia GeForce 8600m GT, and 4gigs of ram with a Windows XP Pro VM that was upgraded from Parallels 3. The hardware setting values are default within the Parallels VM configuration (I believe splitting everything in half from processor to ram to graphics). FYI- The software functions flawlessly when used through a bootcamp only installation without parallels. Also, I had similar problems in Parallels 3, hence the upgrade. Does anyone have any experience with the proper setup for use with Microstation and/or any other software programs that rely on DirectX 9c? I would be disappointed about my sunk funds if Parallels advertises Directx 9c operability when/if it does not function as advertised. Hopefully there is an easy fix that I am missing. Many thanks.
