Hi Daniel, I didn't change anything in the apps. I just compiled in release mode and started testing. (windows xp, Visual Studio 7.1) vsync was accidentally on, so I'll test again tonight with it off. Unfortunately, the OBJ error is much more serious than that. I'll try narrowing down the problem, but it only seems to happen with objects exported from Max. Will let you know as soon as I have more info.

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.
