The man's a genius! Indeed, that's exactly what it was. I didn't make the connection between the FPS from glxgears and the sync rate of the external Samsung LCD monitor I'm using (I use TwinView in a 2-head configuration most of the time). You also explained why it didn't appear in Fedora, since I didn't use the nvidia config utilities there and so the VBlank wasn't syncing. Once I turned it off in nvidia-settings in openSUSE I now get around 1900 FPS from glxgears.
Thanks so much, Renan, for a truly useful response... --ted Renan Birck said the following on 12/07/2007 07:58 PM: > Ted Markowitz wrote: >> I'm running the most recent openSUSE 10.3 kernel on a Dell Latitude 830 >> laptop using an NVidia Quadro 140M graphics chip with 512M of video RAM. >> I also have the latest version I can find of the NVidia native driver >> installed (100.14.23) and am using Xorg 7.2 as the X Server with >> Compiz-Fusion running.
