nVidia-Settings cuts my performance in half...

I've noticed that if I run the program 'nvidia-settings' in an X-session, my frame rates decrease almost by half. What could cause this? I noticed that after a rebuild of the program in question, the problem wasn't as bad.

High quality antialiasing causes a drop in frame rates for sure. In nvidia-settings there is a checkbox for these override settings. It could be picking them up when run.

Maybe so. Oddly enough, why doesn't it enable them permanently? I mean, it should, shouldn't it?

Thanks.

It's some comfort to know games were still playable, but at 1/3 the frames. From 40~70 to 15~30.

They ran, and to me were playable, but not as playable as before. I'll tweak until I find the perfect fit...

I always have Anti-Aliasing forced to off (check "Override Application Setting" and put the slider to "off" position), cause in my opinion it doesn't smooth the texture borders enough compared to how much it lowers fps. Instead I play games with 1280x1024 resolution, so there's not so much of need for AA. I also have Anisotropic Filtering set to 8x ("Override Application Setting" checked), cause that doesn't lower fps by much, but improves textures quite alot.

Also make sure that under OpenGL Settings:
- "Sync to VBlank" is not checked (checking it will drop fps, but will get rid of possible image tearing in games).
- "Allow Flipping" is checked.
- "Disable use of enchanced CPU instruction sets" is not checked.
