A video issue that I've come across is causing me a bit of grief:
On my Vista x64 Ultimate installation, I use a fairly capable PCI video card (an old bus I know, but it works for me no worse than any PCI-E card I've ever stuck in it.). I'm using an nVidia GeForce 6200 on an HP xw8200 Workstation. I have 512 mb of RAM on the video adapter and 7 gb of DDR2 system RAM on the board.
Here's what happens (and it took me QUITE awhile to trace down this iussue). When I enable memory remapping in the Bios to above 4G, the video becomes jerky when there is motion (scrolling or dragging windows). It will stop moving momentarily and resume mvement, or else it leaves severe trails while moving. In the process of tracking this issue down, I swapped out the card with two PCI-E cards: an ATI Radeon Sapphire of sorts and an nVidia Quadro 1300. I had the same symptoms on the Quadro, but not the ATI. Both of these cards had 128 mb of onboard memory. The ATI seemed to overheat mind you, as I received the appropriate beep codes every now and then. So I didn't want to continue using it.
On both nVidia cards however, I found that if I defeated the memory remapping feature, the video worked flawlessly. My system ran with aplomb (even with Aero): HOWEVER, I only have use of 3 gb of RAM. Oh sure, if I go to "Computer" properties, it says 7 gb, but if I go to Task Manager -> Performance, it shows total swap (really memory [I have my swap file disabled]) as 3003 mb. As soon as I renable memory remapping in the bios, my total commit size returns to 6597 mb (7 gb minus video which is correct). However, the jerky video resumes.
Last year, I performed a test installation of Vista x64 and at the time, I was using an nVidia GeForce MX 4000 PCI card with 64 mb of RAM. Although it was a tad challeged with Aero, it worked PERFECTLY with Vista Basic, which I was happy with. That card began to fail shortly thereafter, so I replaced it with the GeForce 6200.
Keep in mind that the nVidia card that I am now experiencing these issues with under Vista x64 Ultimate, worked PERFECTLY with XP Pro x64 Edition. I have tried multiple drivers (the WDDM drivers supplied with Vista, and several Forceware generations including the latest and greatest.) I have ensured 3D generation was always set to "Performance"
I wonder what gives?
