Hiya,

I ran into a bit of a complication with the performance of the OGRE 3d
engine here.

The scene I am using is basically made up of:

-5 1024x1024 textures (trees and shrubs)
Instanced in 300 tree objects across the scene
No complicated geometry. The landscape mesh they are placed on is
about 400 polygons.

FPS in OGRE-mode: 7
FPS in SL mode: 60

System:
Intel Core2Quad Q8200
Nvidia GeForce 9800GTX
8gb RAM

I don't even want to imagine how this runs on lower-end systems. Is
there any way to fix this?

(My made up solution, create all the trees in a 3d mesh and make sure
the textures are applied correctly and so forth, that way you only
have one texture that is tiled across the entire mesh of trees, but
that should not be necessary...)
