Hello, I had the same problem and I know the answer - Post-Process Anti-Aliasing:Off
- Multisample Anti-Aliasing:Off (The "Off" option isn't the first one, it's the second option)
Hope I helped you!!!
(I only tested it for Glaz, I don't know if it works for Pulse)
By the way, I have the same video card exept that I have the 4 GB edition.
