rendering by Ogre

[CrystalH]

Well I think view distance is good enough to do clipping, it can be adjusted so every track would render well. Ogre has support for LOD,paging and instancing geometry though.
The thing that's better is that VDrift's direct rendering implementation in OpenGL is fast. Seems like Ogre is slow compared to it.
I've checked VDrift on Hungaroring06 and in this place it drew 3455 of 5166 no2d_noblend objects and 1073 of 1074 no2d_blend, so 4528 of 6240 track objects and it had 56.5 fps there, so it manages big batches pretty good.
Another strange thing is that I'm using DirectX9 renderer in Ogre (I have WindowsXP) and as I checked the OpenGL renderer it gives half of the framerate. Don't know, maybe it is written somehow slower ?
As I tested with no particles, trails and nothing from track rendered (only car and hud) DX gives 1050 fps, GL only 600 fps.
Yeah, ribbons aren't for tire trails, but better those than none I think, and using them was easy.
