Problems with an ATI Radeon 9700 Pro

I'm wondering if anyone else has encountered problems with OpenGL working properly with an ATI Radeon 9700 Pro. Basically, when I boot up a copy of TGE (any mod or game I've encountered so far), the OpenGL display will only render a small box around my mouse. Lucky for me, the sounds help guide me until I can change the mode to DirectX (yes, I know I can specify it as a boot option)

In general however, OpenGL fails miserably. Note also that the size of the rendered block changes depending on resolution.

Any ideas ?

Michael:
I have the same card as you and have encountered the exact same problems you described. A quick fix for it is to turn off all Anti-Aliasing and Anistrophic Filtering. Even though your game will not look as smooth while testing, it's the only way to make the ATI Radeon 9700 Pro work with the current GUI process in the Torque Engine.

The reason it does this is because the ATI card clears the back buffer during each process so you only see what's behind the mouse cursor. I believe Tim said he was going to work on it so it refreshes the GUI's to make it work on all graphics cards.

Hope this helps.

thanks for the quick reply. I was looking into the code myself. I think there may be a config setting that will allow us to use the AA and the filtering though... it may be an openGL setting. I'll take a peek.

I have the same problem with my 9700 card. the standard ati control panel does not have the ability to turn off AA and AF, only change it to "application preference". curious how you did this. messed with the settings, but no luck.
