I tried the Farmhouse on my Mac Pro.

Quesa 1.8, IR: 14.9 FPS

current Quesa, OpenGL: 15.0 FPS

current Quesa, IR: 15.7 FPS

The main reason that the OpenGL renderer is a little slower than the IR 
seems to be the visibility culling in QORenderer::Renderer::SubmitTriMesh.


Anyway, you need to improve your model.  The farmhouse model has 
multiple references to various groups.  Of course in some cases multiple 
references can make sense, for instance if the references are subject to 
different transformations, but in this case the multiple references are 
just siblings in a group.  That is, you're rendering things multiple 
times for no apparent reason.  When I removed the multiple references, 
the model rendered almost 10 times faster with no apparent change in 
appearance.
