GPU Caps Viewer vs. Intel OneAPI

[Stefan]

Just wanted to try the latest OpenCL CPU driver from oneAPI

After installation GPU Caps Viewer quits without error message.

It appears that oneAPI installs 2 drivers

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Khronos\OpenCL\Vendors]
"C:\\Program Files (x86)\\Intel\\oneAPI\\compiler\\latest\\windows\\lib\\x86\\intelocl32.dll"=dword:00000000
"C:\\Program Files (x86)\\Intel\\oneAPI\\compiler\\latest\\windows\\lib\\x86\\intelocl32_emu.dll"=dword:00000001

After disabling the emulator driver GPU Caps Viewer worked again, even on an AMD CPU

Thanks for your test Stefan.
Looks like the OpenCL emulator has some issues with the old OpenCL code of GPU Caps Viewer. Or it's a bug with 32-bit apps...
Is there something interesting in the log file?

I found an old GeeXLab demo that lists the OpenCL devices:
https://www.geeks3d.com/r/8000

Could you test it with latest GeeXLab 0.52 win64?

Nothing.

That works fine.
oneAPI has even a 3rd driver for Altera, but only in 64 bit

Furthermore i added the OpenCL drivers CLVK and MESA CLon12
These are highly experimental though and fail with black screens in any application
