As a 2.06 user with the same hardware (and also 10gb of ram) and two monitors, I'm looking forwards to any tip.
I was looking forwards for VMware 3.0 to bring unity to an usable state on multiple monitors, but I guess that's too much to ask. I might have to try Parallels again. I have a Mac Pro early 2008 with 8 cores and an NVIDIA 8800 yet unity is super slow when scrolling and moving windows.
i second that, its barely useable even on such high end hardware.
What application specifically are you having issues with, how much screen area is the scrollable region taking up and do you have any surfaces/windows overlapping that area on the Windows side? Are you running any apps on Mac OS X at the same time that would allocate some sort of 3D surface perhaps?
I'm running Windows 7 32-bit with 3GB allocated on the 3.0 release with the default WDDM and 3d enabled on the latest 17" MacBook Pro with 8GB, etc.. I actually have no issues at all with the Unity scrolling performance in Visual Studio 2008 running in a maximized window until I launch my Mac-native World of Warcraft (purely to test this issue of course) either on the same Space or another Space.
Well, I too play WoW occasionally, and usually when I do it, I have two vmwares: Vista 32 and XP 32. (VS2008 and SQL respectively).
The performance of VS 2008 inside Vista is "acceptable" (although sometimes noticeably slower than that I had with Parallels back in 3.0). However, if I switch to Unity, window redraw (in Windows applications) becomes as sluggish as you can possibly imagine.
This is not a tools/install/etc. problem. I've been using both VMware and Parallels since the first Apple Intel computer. Unity and Coherence are definitively slower in terms of redraw and screen movement. Now I don't know what VMware 3.0 brings to the table but 2.06 is as bad as usual.
I have two screens, running different resolutions but neither Windows Vista (32 and 64) nor XP 32 had problems driving this setup under boot camp native. OS X of course has no problems whatsoever.
It is only when you activate Unity where things go down…
I had this problem on a 1st Gen Macbook Pro and still have it on a Mac Pro 2.8 dual quad.core with 10gb Ram and an NVIDIA 8800. This is not a hardware issue AFAIK.
