It would be helpful to see the figures without the mouse lag fix, even though I know it's required for any legit release. My thoughts on the subject are that the DX module could be just as fast or faster than OpenGL if BRL would take the time to further develop it before going on to the GUI and 3D module. DX support originally came out of no where, which leads me to believe it was a rushed effort. If BMax is to be a serious game development language (on Windows, at least), I think the mouse lag issue and general DX slowness needs to be addressed.
