Hi all,

Running the Benchmark application with SetSyncRate(0,0) and 10,000 sprites gives me 98-100fps consistently. If i rem taht line and put SetVsync(1) i get a solid 59.9-60fps smooth with no tearing but occasionally, every few seconds, it dips to 45-50fps and you get the slow mo thing happening. During the slow down, there is NO tearing. So i decided to rem vsync out, put SetSyncRate(0,0) back in. I also forced vsync on in the nvidia drivers instead of application controlled and it runs at a constant 60fps, smooth, no dropouts. Whats going on with the vsync command?

Try it with a different monitor and see if you get the same result.
