--- Comment #29 from Roderick Colenbrander thunderbird2k@gmail.com 2009-05-15 12:20:17 --- The GPU is a little bit weak but should be more than sufficient for Sketchup and I also wonder whether the app explicitly checks for the GPU. The OpenGL used to be a pixel format enumeration issue. I'm not sure why it worked for some users and not for others (even if both used Nvidia). Now our behavior more closely matches Windows. A +wgl log could be useful and of course tests on some different cards.
