Thanks Heiko ... 225 it's not bad too

Good idea to give me information about your configuration, but as it's a 3D software engine, it's rather your microprocessors that are important.
I have a very old PC (which I have to change soon) and I can't know the speed with the new microprocessors... I have ~50 fps on my dinosaur pc

The engine is not yet very optimized so your results are very encouraging.
I am interested in 3D software engines for pleasure but also for ease of export (iOS, Android, ...) and future adaptations (for example with others API).
I would probably make textured versions soon.
Some may also be interested in the 3DS loader.
-- EDIT : In fact, it's also related to the GPU and not just the CPU because I use an opengl function for the final display (an equivalent of mem2sprite) and it's really slow with my old Intel graphics chipset

Without this function I have ~320 fps --
