NASA-like setup

Posted in experimental with tags on September 2, 2010 by Francois Wunschel

After a long fight I finally managed to get our NASA-like setup running at 60FPS on all outputs, on a single MacPro 2009 loaded with GT120 cards. Strangely, it works only if all the fullscreen outputs are VGA, except one DVI.
That’s a lot of particles for a single Nehalem core at 2.26Ghz … (since I don’t know how to multithread QCviews yet, if that’s even possible).
The good point is that I can still run Photoshop on the control monitor without a framedrop.
EDIT: due to some apparent bug in the GT120 drivers, depending on reboot, the framerate is either 60FPS or … 30FPS. Pretty lame actually.
EDIT2: thanks to David, the super-coder, we managed to disable vsync on all openGL contexts. Now we have 60FPS ! Yeah, 60 ! (I love reading that number on my FPScounter…)
