no opengl, fallback to directx?

BlitzMax Forums/BlitzMax Beginners Area/no opengl, fallback to directx?

i do have a perhaps a bit an amateur question to blitzmax, but the following question pings around in my head since some weeks while watching the development of blitzmax: if i have a system which only supports directx with a good gfx card but no direct opengl support will there be any fallback to directx then to keep up the graphics performance? is this technically possible? i've made some tests on diverse systems and i observed that on machines with no opengl support of the software drivers the fps drops down to 1 fps while having up to 60 fps on systems with "normal" open gl support. is this a normal symptom?
