I downloaded latest Second Life Release Candidate and everything runs great! 30 FPS with everything maxed (video card 8800 GTS 512MB). When going back and trying to run the 'regular' SL ver 1.19.1 I'm getting about 0.8 FPS with a big kind of transparent red square in the bottom left one fith of the screen. If I set the quality and performance to Low I still have the red box, but my frame rate jumps to around fifty.
I thought my graphics card was failing, but putting an older 6600 card in my machine gives the same results (but a slower frame rate).
I've clear the cache, and reinstalled SL with no luck. Any one have any suggestions?
