Hello All, I posted about this a couple of weeks ago, but didn't have much info.
I'm getting really poor framerates ( < 10 )from our software which is based on osgdistortion on a Core 2 Quad machine with a Quadro 3500 running Ubuntu 7.10. My P4 + Quadro 3450, and my Core 2 Duo + Quadro 1600M laptop run the software fine (also Ubuntu). I upgraded the Core 2 Quad to Ubuntu 8.04 (to match the P4) and the problem went away. The other day I noticed that the Core 2 Quad could only see one of its cores - I upgraded to an SMP kernel, and the problem came back. In the last 2 days I've been experimenting with Fedora + CCRMA - interestingly with an SMP kernel, it exhibits exactly the same behaviour. I don't see this behaviour under FreeBSD (6.2 and 7.0). I see this behaviour with osgdistorion --dome, and also osgprerendercubemap. I suspect that this is a Linux/SMP problem rather than an OSG problem, but I thought you guys might have seen this behaviour, or know workarounds...
