which works a bit like OpenGL or directX, that means all lines are drawn before the graphics is updated. But only for this call, its not a scene rendering for all draw commands.
Now, this api call does still work for i5 HD graphics, but it is incredible slow. It looks like that it is internally changed to a set of moveto-lineto commands. I get comaparable timings when i switch my code to a loop of moveto - lineto.
Why does HD graphics dont support anymore fast 2D accerlation? I think some CAD Software would require this also.
Do you have better performances with other apis except for opengl/directx etc. (we cant use scene rendering for some reasons. Is GPA supporting this call ?
Thank you very much for help
