Don't work with my 5850 extrem (on 10.7.2 (11C57)), i've got the same kernel panic as Simania_NL.

Your Asus works out of box ?

Ask other ATI/AMD 6870 users which kind of injection (chameleon, ATI INIT,...) they use.

I don't use any injection, the 6870 Reference card works out of the box, with me at least.

Not compiled correctly for Fermi?

Guy in OpenCl Fix thread says he fixed your binary and got 329 fps with 480GTX

Since my GTX480 is getting 16fps still while doing quite well in the Luxmark 1.0 bench, so clearly issue is with the app.

Look forward to getting accurate results.

I have 1 of most Fermi cards so can provide quite a bit of info once this is fixed.

If some OpenCL app works , like luxmark, it doesn't mean all OpenCL Code may work on some gnu type.
Its not an problem of the OpenCL code (comes from Apple) the problem is in the OpenCL framework / driver which compiles
the OpenCL code each run for the found gnu type.
Same as said before: Ome of that reason most software didn't use OprnCL or use only more uncomlex code.
Same happens to kuxmark at the beginning - working or not also depends from gnu type and driver versions at same OpenCL code source.
Don't worry if some of the OpenCL apps may fail . will be fixed by Apple in the further.

THANKS.
Perhaps it would help others if you can tell them what files need to get patched (overwritten) and make an download with that file set.

You may try same Source little different Compiler Options, but i think that will not help with some gpus.
FPS may be little different because main App (affected by the compiler settings) which communicates with the gnu/opencl runs little
different speed by the changed compiler settings.

Sorry mitch_de V2 did not work for me also

Does it make a difference if I have Xcode 3.2.6 installed, had some problems installing latest version of Xcode?

NEW: NO MULTISAMLING version available.
more OpenCL speed related, less OpenGL load for the gnu.
i , 9600 GT, get now 103 fps (94 fps multisampling).
You can press space key to pause which avoids updating OpenGL - even more OpenCL gnu compute fps.
i get 223 FPS in pause mode.

DL for the no multisampling version added.
Would be nice if you tell / update your fps values run/pause again with that no multisampling version.
