It's not finished yet.

I take it OpenCL won't solve the issues with abnormal slowdowns in games such as Resident Evil 4 and Zelda: Twilight Princess?

I get between 3-5 fps increases in a couple of games using ati's opencl driver, but there are a ton of graphical glitches

Um... IMO the bigger news is that I'm pretty sure this makes Dolphin the first non-Mac program to support OpenCL.

extreme64 : The decoding of a major texture format is now fixed. Could you test again ?
Also, if you find some other texture decoding error, try to enable the texture format overlay in the advanced tab of the graphic plugin and report the name to me here please.
I already know that CMPR textures aren't decoded properly by the OpenCL software for now so I have disabled the format until I manage to fix it, it is handled by the old "cpu" code which works fine.

Even after the latest OpenCL work I still get a ~20% speed decrease in SMG observatory. (Can you name more games/places where OpenCL makes a measurable difference?)

Also there seems to be a change for the worse with ISO loading: In my normal build loading any GC game is practically instantaneous and Wii games might take a second. But with my OpenCL-enabled build it takes ~15s to load any game.

hmm I make a build without any change and the "delay" when loading discs is normal ( I don't have very much games )

The OpenCL decoders are compiled after the game starts each time. This is why there is a short delay.

Is no one else with an ATI card getting OpenCL compile errors when starting a game? The errors pop up in a window in front of the game.

I have an ATI Card and having a lot of errors that pop up in a window when starting a game

Compilation of the OpenCL code is done when a game is loaded and it takes some long annoying time, especially when you try to debug it !

I don't have any ATI card, so the code is only tested for a NVidia one. It should be about the same but it's not. I'll have to work closely with someone having such a card that can do some tests and "fix" the code... or wait for better drivers on both side, none is perfect and I have grudges against NVidia's too !
Also, if someone with a ATI card and enough programming knowledge wants to try to fix it, it would be fine be me !

I have an ATI Card but don't know about programming. I can help you with some testing
