Photoshop has started acting very strange. It's incorrectly detecting less than 512MB VRAM (AMD 5770HD, 1024MB VRAM). I thought it may be a graphics driver issue but neither the latest stable nor beta seem to effect this.
Since 3D features have been disabled, the application is unstable. Changing tools a few times will always result in an appcrash exception.
System specs:
Windows 7 x64 ultimate
Core i5-3470
16GB RAM
AMD HD5770
I have a feeling I know what's causing 3D mode to disable and that's the integrated card on this motherboard. This currently acts as an additional monitor output and is set as the primary device in the bios (and I can't change this) but shares some state via some LucidLogix thing on the motherboard. Is there any way to disable this VRAM check?
