Try setting maxfpsbk to 10 or 15 if you haven't already, and maxfps to 40. Also, turn off all the graphics options and turn down the sliders to minimum on everything but terrain distance, which I would set to about 1/3. See what you get with that. I would also go check your NVidia control panel's 3D settings page and make sure you have the following settings if available:

  • Anisotropic filtering = OFF
  • Antialiasing = OFF
  • Multi-displaly/mixed-GPU acceleration = Multiple display performance mode
  • Texture filtering - Quality = PERFORMANCE

Then I would go set all your wow clients to 800x600 in-game resolution. (NOT maximizer! That's a different setting.)

See if those help any and let us know.

Cheers and GL!
