View Full Version : OpenGL project runs VERY SLOW on one new computer

I created an OpenGL traffic animator that runs at reasonable speeds on all of my in house machines. One of my customers, though, is reporting severe slowness on his fairly new computer (with adequate resources). The slowness occurs even if the animation is paused. Just trying to move a dialog box around on the screen with the animation paused takes a very long time for the window to repaint.
Please help me out.
The most common reason is that the drivers that ship with Windows (whatever version) do not support accelerated OpenGL and hence everything is done using software emulation which will result in VERY low framerates.
Even with proper drivers there are circumstances that can force the software emulation to supercede the accelerated drivers. Mathlab is such an example.
Without more information its really hard to tell.
