__GL_YIELD pratical usage?

mocharhw · 06-22-09, 03:40 PM

In my never ending quest to make my videos and games look visually appealing (sync'd, smooth, etc..) I've been playing with lots of xorg.conf, nvidia-settings, and environment variables. In the nvidia manual section 11, there is an env variable called __GL_YIELD, I currently have it set to "nothing" in my .bashrc. I'm not sure if it's doing anything, but my video and opengl rendering is very nice now so I'm just going to leave it in there. I made too many changes at once so I'm not sure what effect it's having.

Can someone explain in non-programmer language what practical user effect __GL_YIELD=nothing has on opengl rendered graphics (such as in games and emulators such as SDLMAME) as well as opengl rendered videos (such as selecting an opengl rendering method in mplayer)? I'm talking about it's usefulness to a user. Thanks.

I have it in caps as the nvidia manual says. I'm not sure if it makes a difference.
