Well, the disc didn't come today (Netflix is so slow these days I'll have to cancel), so I tried some of the suggestions. Running VA and TrackIR as administrator has them working. Thanks.
I've always auto hidden the taskbar, but I've set it to not hide. In limited testing, I haven't had it disappear, so that's good. But it has become unresponsive a couple times, but not since I've stopped messing with updating drivers, so hopefully it will stay working now.
I haven't gotten SLI working yet. I've tried updating the drivers, then d/l and installing 368.39 from several weeks ago, that people on the main forums said was working, and also played with some of the settings, but no dice so far. I guess the next step is to try even older drivers.
The odd thing about SLI is that it does have some affect. With a single card, the main menu has glowing text, and with two it is more crisp, but no real difference in FPS.
