Hi Scott, Welcome to the world of server motherboards... Looking at a couple of the things you ran across, I think you've already discovered some of the basic tradeoffs. Dual processor systems are often slightly slower clock speeds than the fastest single core processors. I've never been sure why this is, but I suspect it's amount of testing that goes in to development along with the additional complexity of dual (or more cores.) And your trouble with video doesn't surpise me a lot. I've got an early athlon MP system with a server motherboard (Tyan.) The video options never seem to be as complete on server systems. Also, I saw some commments in your Anandtech thread about video options. Note that even the nvidia cards with series numbers in the x200 (5200 for example) are rather poor performers. I would not bother making a special effort to get a x200 nvidia card working for OpenGL. If a pci-x card with a x600 or x800 number (6600, 6800, or 7800 on up) could be made to work, then it might be worth it. Otherwise I would not bother trying to get the OpenGL support setup for cinelerra. One comment on performance: In my recent builds and testing on AMD X2 64bit suse 10.2, I found that optimizing the cinelerra build was of no benefit, and sometimes was a penalty. If you are building cin yourself, and have used any of the additional optimization flags we've covered here before, you may get better performance bt removing them from your build on FC6. -- Kevin _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
