I'm using a different PC for a while, and I popped an AMD HD7700 in it. Works great, but I noticed GLBasic games were acting choppy, but "reporting" full FPS. I looked at Catalyst Control Center, and noticed "Open GL Triple Buffering" was disabled. Checking the box and rebooting completely fixed the problem. Is there a way to make GLBasic tell the graphics driver we want that on? Seems odd to me it'd be off by default I guess. I tried unchecking it and the choppy display came back, so it's definitely triple buffering...
strange... I thought a vsync should do it, no need for double or triple, but just my guess.
I have been running intel+nvidea for a long time, my last amd was about 10 years ago, so I quite can´t know what is the deal.
@Darma
Tripple buffering reduces performance by a factor of 3.
Have you tried the "force off" option for vsync?
I use nvidia this way, with no bad side effects.
