In case anyone's watching my numbers, I just switched from the 175.16 to 177.35. No modded inf, just told it manually that I have a GTX 280 (I wish).
No change in the viewer breaking, and I still have a huge slowdown leading to an eventual BSOD if I don't close the client before trying to run 3D. I tried 174.55 briefly and no change there either, so I went with the biggest numbered driver.
Expect more points tomorrow, though I might have to dump this for a release or two if I can't figure out/work around the horrible slowness issues. I bought that 8800GT to run games, not to slow down my machine and refuse all 3D (That's why it's my 8800GT and not this 2400 Pro that holds down my desk). I also lose all 2D/overlay/VMR/EVR surfaces too, so no video. This is an even bigger deal breaker. I can live with gaming/no gaming modes, but having to switch off GPU2 whenever I sit down and turn it on any time I leave my machine is NO GOOD.
A promising start, but only that.
