Wow! You really are a complete DUMB ASS that knows NOTHING about openCL. Really you have NO CLUE. Not one test utilized openCL. If there is no openCL code to be ran then there is NO loss of openGL rendering due to the shaders being used for openCL. Please Qaridarium, try to keep your comments on subjects that you might actually have a clue about. Clearly GPU computing is not one of them. Applications don't "automagically" use openCL.
