I wasn't sure if this was a driver issue or not, but the GPU Load Balance indicator, while operating normally in Direct3D games, does not function for some reason in OpenGL games (Call of Duty, Doom 3, etc) for some reason. Is this a known issue (didn't see it in the release notes) or bug? Just curious.

Sorry I should have been more specific, this only applies to SLI systems. The GPU Load Balance indicator is supposed to show how your selected SLI rendering mode (AFR or SFR) is balancing the load between your two GPUs. It works great in Direct3D apps but doesn't seem to function in OpenGL ones. The lines appear but they just sit there.

*bump* can I get a response from one of you SLI users out there? This is really confusing me. The games I'm testing are largely CPU limited so I can't really tell if my SLI is working or not.

What do you mean? The bars are there, they just don't move at all. Is that what you see, or is it just that there are no bars at all?

Sorry, yes the bars are there and do not move. The verticle green bar is empty.

Ah, cool. OK just wanted to make sure, that kinda had me worried for a bit. :)

That's normal for an sli system.

Heh, seems like SLI still has quite a few issues to iron out. It's very confusing for a first-timer. :D

Yeah, a few of us went through the same thing earlier. SLI can be a little confusing at first because it's different and you're not sure how things are supposed to work, what some of the settings are, etc. Here's our old thread where it was essentially a case of the blind leading the blind as we tried to figure out what was going on. :)

Oh man, that thread answers every question I had!! Thanks a TON for the link, I tried searching but I guess I wasn't specific enough. Phew!
