Hey Mitch, just to let you know that my gtx 560 is the non ti version - 336 shader (2 shader units are laser cut whilst the 560ti has 384 shader units) or according to your luxmark - 560 = 14 compute units and 560ti = 16 compute units

Interesting: OpenCL supports using different vendor gpus same time.
Windows, sala : AMD HD7970 + Nvidia GTX 470 = 2096 http://www.luxrender...tail/result/360

Problems or not may vary much with driver versions and gpu types! But it works at least for that combination - absolute impossible with CUDA or AMD Steam.

Maybe you need install newest NVidia Win7 64 Bit drivers (again).

perhaps you need Intel OpenCL Runtime driver for Win7
http://software.inte...ols-opencl-sdk/
Select the runtime only for windows. I dont think you need the complete SDK

Works great, thanks... Just {censored} implementation of opencl 1.1 in nvidia drivers...

Mac OS X 10.8 DP1
OpenCL works but wrong results - Luxmark gpu or cpu+gpu give wrong results. Pleace checl if that happens also to your (working in Lion) card.

EDIT: ML DP3+update fixed that :)

Luxmark Version 2 :)

The nVidia Mountain Lion support is great. I now have three BenQ 24-inch displays running under OS X.

Then OpenCL needs patch or its otherwise not supported (patch will not help)

I've tried the hex editing thing posted there but nothing, I get RUNTIME ERROR: No OpenCL device selected or available. In Windows 7 it is fine. Latest drivers and CUDA driver installed

CUDA Drivers are for CUDA, not OPENGL nor OpenCL ;)
Maybe you ask at the Nvidia Thread for OpenCL patching.

Can somebody tell why my HD5850 Extreme would score 515 on W7 64bit while it would score 135 on OSX 10.7.2?

Which Scene with 135 ? Scenes (3 available) have much different result count! Perhaps you benched different scenes on Win/OS X?
I looked in the Luxmark resultbase and that 515 of AMD 5850 / WIN64 can NOT be the most complex room scene - maybe it was the scala (middle complex) scene?
AMD 5850 / WIN64 are around 300 (295-320) in that most complex room scene - no way to get 515 in that scene with that card.
But in middle complex scene (sala) AMD 5850 / WIN64 getting around 600.

Normally OpenCL Luxmark runs same or often a bit faster than WIN64 Bit native.
I get 754 with the simple Luxball scene and Nvidia 9600 GT - your 5850 should perform much better.
In middle complex scene (sala) i get 74 and most complex scene 41 (room) - you see much different results 754 - 74 - 41 , depend on scene you benched. An AMD 4830 gets 93 in room (9600 GT 41), yours should perform >= 130.
Also - newer OS X Version should perform better OpenCL on some AMD gpus. For Nvidia there is near no speed diff between 10.7.2 and 10.7.4 dev .

GREAT : With 10.8 DP3+update Luxmark again working - with ML DP1+DP2 LM 2.0 wasnt working correct (render preview damaged/wrong).

Failed to give full specs. Sorry!
I am using a Laptop.
HP Probook 4530s
i7-2630QM
Intel HD3000. (no Open CL support)

eGPU HD5850 Extreme connected @x1 2.0

Well when running LuxMark v2.0 Scene=Sala Mode=OpenCL GPUs only
W7 64bit gives me around ~500
While 10.7.2 gives me ~169 (best score after several tries)

Is it the x1 2.0 bandwidth limitation.
