I have checked the recent update of Open CL drivers v1.5 and the loading times of compiled binaries have not improved. It takes almost 20 seconds for my application to start when loading binary program for Intel drivers. It starts almost instantly with Nvidia and AMD drivers. There is only a small difference between times required to compile the code and the time needed to load already precompiled binaries with Intel Open CL.
Are there any plans to improve on this?
