OpenGL Driver Help

I have to turn off OpenGL Hardware Acceleration in SketchUp to use SketchUp with my ATI V5700. However, some add-ons, such as LightUp, require hardware acceleration to be turned on.

Does anyone know of another option - like changing settings on the Display Adaptor to lower OpenGL acceleration, which would let me turn hardware acceleration back on?

Have you tried installing different versions of the driver? The ATI website says the card is meant to be openGL compliant, so with any luck they will have made a working driver at some point.

As Remus says, try different versions. Also, some people say good things about the Omega drivers ( http://www.omegadrivers.net/ ) but I really don't know anything about them.

Some ATI cards (like my antediluvian All-in-Wonder one) need to have Fast Feedback turned off to work with SU with Hardware Acceleration on.

I downloaded a newer driver from ATI/AMD but it wouldn't install on the Lenovo.

I did update the Lenovo ATI driver on Dec 14, 2008 however, so it is fairly new

Its worth looking for older versions of the driver as well, sometimes they can work better than newer drivers.

One of my machines will not display properly with acceleration on, but it doesn't prevent me from modeling as long as fast feedback is off. Just can't see the colors on the face properly.

While not related to your post, if I insert certain components, the face colors correct themselves.

Glad you figured it out al, they can be mysterious things those graphics drivers.

I have just update my drivers on a vaio laptop Nvida Geforce Go 7600, but not from Sony but from a moded driver site (Gaming), as Sony and Nvida have not provided any updates, and it works fine, however when updating the drivers for the family computer with Geforce 6500 from Nivida, I got the dreaded cursor trails, I did not want to turn off hardware acceleration as you Al, so changed the capability in GSU preferences opengl setting to a lower quality and it went away

EDIT I have also just come across this in model info that might help somebody, if they experience display problems

[Later Edit]
I must have been dreaming when I thought this worked for me. Now it is broken again.

I went into the ATI Catalyst Control Center - to 3D / Standard settings and moved the Performance/Quality slider one to the right, from Balanced to High Quality. (It was not easy to figure out which setting to change, and the ATI help system offered no help)

Then the SketchUp Bug Splats stopped and LightUp also works!
