Unfortunately i also agree...
I was thinking about it a bit more and it might be a bit more complex then just optimizing models and textures.
Also there should be taking in account what kind of camera options there should be in case of RT-3D-FFVII....3rdperson,1stperson or fixed, or all options.
for large scenes....well background data streaming etc. etc.
For now, as i already try to optimize the models as much as possible (to lower render times) it might be not that difficult to change, however as pointed out before the texturing in my case is not really optimized for games, just for rendering.
so let's stick to 2d-backgrounds and 3d battlefields.
