Hi Michael,

I think I found the solution for my problem.I have to go to properties,then to settings and change my color bits from 32 to 16 bits then in moi3d everything rotates smooth and fast.When I had older computer I had the same problems with some games,and I tried it with moi3d and it works.Even surfaces with lots of details running smooth.Now I have more will to continue to work and practice with moi3d.If you have better solutions please let me know.Thanx in advance.
