Open CL texture decoder not working anymore

[TSM]

I'm seeing a substantial speed up with OpenCL in Twilight Princess (HLE audio). I went from 18-20 fps in Hyrule Field to 25-28. I was sub 30 fps in a lot of areas outside Hyrule Field before, but now I'm a solid 30 just about everywhere else. I didn't initially bother with the setting because I read that it didn't do anything useful, but after reading someone saying it sped up Twilight Princess I gave it a shot.
