Hi guys.
I've gotten kind of tired of 2d benching and are trying to make use of around 20 graphics cards I've collected in recent years. I started with 3 way SLI on GTX 260 - man these cards are dirt cheap now, even got one for free
Trouble is, even with 2-way, my fps is barely increasing! At the start of the test I get good fps, then it drops like crazy in a fews seconds to almost-single-card level. Wth??
Platform is X79 Sabertooth, 4960x,4x4 dom platinum... 1000W psu in good condition.
Tried driver 296.10 and the newest possible, same stuff. Tried 2 different bridges, nuthin. Load is good, both cards are loaded 80-100% during bench. Mostly tried 3dm06 but also vantage.
