Why should we not remove the OpenMP option?

Many of us think the "OpenMP Texture Decoder" option is useless and/or harmful.
I plan to remove it.

Post here if you think there is a reason to not remove it.

If you think it helps performance provide some data.

Harmful?
In what ways?

It's not even available on OS X since Clang doesn't support OpenMP yet, and the GCC is incapable of building any of Apple's headers. >_>

If anything OpenCL should be removed instead...

Many users report reduced micro-stuttering with openMP. I've not noticed it myself since I turned on openMP, but don't know if I ever had micro-stuttering.

If OpenMP really reduces micro stuttering, then this option should remain in Dolphin.

Reduces performance.

Those users need to provide some data then.

I don't think you can prove or disprove microstuttering. It wouldn't show up on a video, and wouldn't affect average FPS enough for FRAPS or similar to detect.

OpenMP should stay.

Otoh, do whatever you like with OpenCL.
