Hello, I searched for this problem, but have yet to find it. I am running VM XP Mode on my Windows 7 RC x64 and am having an issue with input lag. It seems to happen quite often while using my one and only program that works only within XP Mode. It is a sketching software that was designed for use with my appraisal software and I use it daily. I have been trying to ignore this issue for some time, as it is only an annoyance, but enough is enough.
I noticed this right away just runing the VM with provided XP while I was installing software and updates to XP, it would seem to stall out and sit there for upwards of 30 seconds, but then it would blaze ahead to the "current" install % done. Now when I'm doing a sketch, I can draw a line, or maybe even a dozen before it "stalls" and then i have to wait about 30 seconds for it to catch up.
I have the memory set to maximum for the VM, 3,712 MB, while my total system memory is 8GB, my CPU is the Intel Core 2 Quad Q6600 overclocked to 3.25GHz from 2.40GHz and I have dual NVIDIA 8800 GT's in SLI mode. I just don't see a hardware issue here.
I dont have any USB ports open to the VM, as i dont need any of them.
If I overlooked some info, please let me know and I'll update this post.
Any help would be greatly appreciated.
