I have three monitors connected to two separate graphics cards, an 8800GT and an FX5200 (PCI). Now, this setup works fine in regular XP Pro, with driver 175.19; Photoshop CS4’s OpenGL works without a problem save for the brush cursor bug. However, I installed Vista x64 as a dual boot for the RAM boost, and ran into a bit of a wall.
Photoshop now refuses to work at all with the OpenGL enhancements on. It loads (an improvement in itself, used to get stuck at "Reading preferences"), but it’ll freeze when I try to open a file or go to the performance settings. I’m currently using driver 171.16; I know it’s outdated, but it’s the most recent one that works with both cards in Vista x64. I’m also quite sure it’s not the problem; Photoshop works perfectly with OpenGL on if I disable the FX5200.
I’ve tried the registry key AllowOldGPUs_ON to no effect. I’ve also tried both the 64-bit and 32-bit versions, with no difference. Is it possible to get Photoshop working with both cards, short of replacing the FX5200?
Specs:
Intel Core 2 Quad Q9300 2.50GHz
4GB RAM
Over 300GB HDD space available for scratch disk use
EVGA 8800GT
PNY Verto FX5200
