Ok, I setup a batch file to do the entire test suite last night, but something happened where I only got a few results. I'll try again tonight.
Here are the results I received: ---------------------------------------- tie243 (729k) ---------------------------------------- OSG: 44.9264 / 60.4408 // stutters OpenSG: 1757.0 / 60.5609 // fps varies between 59-62fps VRML: 35.265 / 42.9546 // OpenSG VRML file ---------------------------------------- tie486 (1.5m) ---------------------------------------- OSG: 105.645s / 45.8042 // stutters OpenSG: 9858.33s / 29.4957 VRML: 83.475s / 20.0836 // OpenSG VRML file I'm a little surprised to see the large performance drop with VRML files.

Have you change anything in the applications? My results remain the same, although I turned "sync to vblank" of in the garphics card driver menu. (Nvidia GForce 6200 TurboCache) I will try the optimisations proposed by Matthias in the next days. > 2) has anyone else encountered "Unknown Object Data Element x.xxxxx" when > using OBJs exported from Max? I get Warinings like : "Invalid d entry in ./tie.mtl" when loading the obj files with OpenSG, but they work fine nevertheless. You might try deleting the d entries, as they are surplus anyway (all set to 1). I'm very interested in the results you achieved with the bigger models. Cheers, Daniel.
