So, what is going on? Don't you guys quit on me... @Nicolas: You pointed out that the nVidia ICD loader (libOpenCL.so) is only 1.0 (outdated), that is correct, but the ICD specs only require 1.0, so 1.1 possibly should not be needed. See specs: http://www.khronos.org/registry/cl/extensions/khr/cl_khr_icd.txt Although this would require testing. I'll do it later if possible... ~kralyk
