Ok for the workflow but I wonder 3dgs can take plenty of time to compile a map What is it doing ? I suppose that it is storing a lot of precalculated data Should I not expect any advantage for the frame rate ?
I am not the designer of the map compiler so I cannot say for sure. But you dont place your portals manually in GS. So the map compiler has to find portals on his own and finds much more than you would place manually. Probably it creates a huge amount of data to traverse. All this happens on CPU. This also explains why exchanging a graphics card did not speed up rendering BSP levels made with GS, only exchanging CPU could help there.
