Fwd: [osg-users] Visual System Performance

[Radu Mihai]

Also check the state of SLI in Linux 8x Nvidia drivers. People are reporting that there a little performance gains from SLI in the current driver. That had been the case in Win-land too at the beginning, and the 'word' is that the 9x version will fix this issue for Linux. -------------------------- Radu Mihai [EMAIL PROTECTED] On 22-Sep-06, at 12:36 PM, Gordon Tomlinson wrote: Are you running in SLI mode ? if not they run independent and you will be only using one if on a single monitor Do you have Antialiasing, Anisotropic filtering on etc   That's 225m optimized non lilt non shaded non non textured etc.   You certainly should be able to do much better the 5hz   Also make sure you get the lasted drivers, drivers installed and supplied with card are normal quite OLD   Best Regards   Gordon __________________________________________________________ Gordon Tomlinson Email         : gordon.tomlinson @ overwatch.com YIM/AIM       : Gordon3dBrit MSN IM        : Gordon3dBrit @ 3dscenegraph.com __________________________________________________________ Telephone (Cell): (+1) 214-477-8914 Telephone (Work): (+1) 703-437-7651 "Self defence is not a function of learning tricks but is a function of how quickly and intensely one can arouse one's instinct for survival" - Master Tambo Tetsura   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Wasileski, Bryan J. Sent: Friday, September 22, 2006 12:29 PM To: osg-users@openscenegraph.net Subject: [osg-users] Visual System Performance Hi all,   I recently received a couple of new workstations which have the NVIDIA 4500 X2 video cards installed (Dell machines). We intend to run all our new visuals on the machines using OSG. I've been trying to gauge the graphics performance and from what I've seen so far I'm thoroughly disappointed. I'm assuming at this point the boards are not properly configured. The issue I'm having is trying to find a way to test the boards to determine if they are in fact improperly configured or just don't measure up.   As an example, I have a scene database that I load into OSG; at any given moment, the scene has about 40K primitives. I'm only getting frame rates around 5-10Hz - which is totally unacceptable. According to the specs, these GPU's are capable of 225M triangles/sec. I feel certain that only 1 of the 2GPU's is being exercised - I know of no way to verify it.   With all the graphics/visual system wizards who monitor this sight I thought someone out there might be able to provide some advice on getting these new boards properly configured so I can actually test their performance.   Additional info on the new boxes is: 2 Intel Xenon 3.7GHz - Linux OS EMT64 16GB memory   Also, kudos for the flawless 64-bit OSG build. Worked without a single glitch.     Bryan _______________________________________________ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
