More OpenCL work, got XFB converting which needs more optimization. I haven't checked for FPS changes. My desktop isn't the best to test on anyway (Phenom 1, 32 stream processors). The package check doesn't work for me, so I just checked true if you compile with opencl=true. Requires a bit of cleanup still
