Hello Surody,

The problem is not OpenGL but OpenCL (for Computing Language). This is a language for computations on graphics cards. NVidia has its own language named CUDA but it works only on NVidia graphic cards. I preferred to use OpenCL which works on all graphic cards.

Many programs use now computations on graphic cards but this requires to rewrite the concerning part of the program. Sometimes, it is not so easy.

For the number of collision actors, I will set it to 3.
