Hi, Sorry to trouble you on this, but I have to ask someone - to support my hypothesis on this issue!
I'm running Red Hat Enterprise 5.1 using a Gforce 8600 card using the latest driver from nvidia (119.52). I know that P4 stuff is old school and Performer is very old school! And there is most likely nobody else in the world that is being forced to do this but me, however here we go: Up until a month ago I've been using a system that uses Core Duo system (until it cashed) and I was running a program that was running performer and basically the same program using OSG. Both where working normally - naturally OSG was working better than performer! Now, I'm running a P4 system (only deference is the CPU and double the memory) and the OSG using the same graphics card and the OSG version of my project is running happy but the version running Performer has slowed to a crawl when they run together. I ran top and found that OSG is taking up most of the CPU time making me think that OSG runs better on the Core Duo than the P4. My understanding from someone is that the P4 is not exactly a twin core but a single core using threading to behave as a two core system and the Core Duo is a true twin core system, hence OSG behaves better using the Core Duo! One idea that was brought up to me was to move up to a Quadro graphic card. Someone at PNY told me that it's the only card that works best under Linux for OGL. I know I'm going to get the Why are you doing this reaction, but that is the requirements! The user will be able to run Performer and OSG at the same time! The best answer I can come up with is "use Core Duo or better" but that means dumping 64 boxes! :-* Any ideas out there? ... Thank you!
