uhh, ATI OpenCL drivers v9.11 Beta 4 ATI Stream:
OpenCL detection seems to have something still also.
Fail to mention that installation did include the OpenCL.dll's on %systemroot%\system32\ and %ProgramW6432%\ATI Stream\bin\x86_64 and %ProgramFiles%\ATI Stream\bin\x86_64 just wanted to see, if GPU-Z could detect it. The default is kinda funny as in x86 systems it's %ProgramFiles%\ATI Stream\bin\x86 and in x64 it's %ProgramFiles%\ATI Stream\bin\x86_64 and all this required an SDK to be with-in system and as far I looked it I cannot imaging opencl.dll to be ever part of drivers at %windir%\system32 folder as it's supported by multiple platforms.
funny thing is opencl.dll is not registered dll file. I don't have a slightest clue how it could be query. Unless simply by check for the file/version/library .lib. Also Driver alone doesn't make any kind of variable to the system nor does it include the dll searched registry through listing and found absolutely no way of detection does he driver or device support OpenCL.
