On a development laptop I am getting excellent framerates. However, when I run it on my desktop it always runs at a fixed 60 fps. It’s a AMD 1700, and a GeForce4 MX440. Does it have anything to do with the fact that I have an LCD attached which has a fixed refresh rate of 60Hz??
But then again, the laptop obviously has an LCD also, and it’s calculating 800+fps. What gives? Anything I should try?
Thanks,

That’s because vsync is enabled. With vsync enabled the maximum number of frames, which can be rendered per second equals hz.
You can disable it through the drivers (right click on the desktop -> properites -> advanced -> -> opengl -> vsync
You have usually 3 settings there:
-
always off
-
default off
-
default on
[and sometimes also always on] -
Is pretty silly, since you won’t be able to turn it on via software anymore.
-
Is the one you should try (it can be enabled via software)
-
Is also ok (it can be disabled via software)
