Stencil shadow patch
The cause of the slow stencil shadow mode (a change of Ogre's shadowing strategy) has been found and the bug has been fixed. I got the stencil shadow framerate jump from 26 to 40fps with this fix!
As promised the patch is available (139kb). The full download has also been updated with this patch and is labelled RoR-0.29a (check it in the download page).
Thanks to the Ogre team for their quick and efficient cooperation.
Also, thanks to Thomas financial and technical contribution, the linux version is on its way but we ran into unexpected incompatibility problems between linux distributions. Thomas and me are looking into it.
Have a good drive!
