run:

ESC key abort / [GPU] Compute: 2.40 ms Display: 417.48 fps

 

pause:

Starting event loop...

ESC key abort / [GPU] Compute: 1.41 ms Display: 708.04 fps

 

Oh, the first one was with Multisampling, this is without, was hard to catch the text because of heavy flickering, see title for compute time and fps.

It can be that the OpenCL compiler (complies on the fly at runtime) better knows 47xx gnu than 5xxx gnu type and so better produces the gnu program.

Also it seems that Nvidia gpus GTX get much faster gnu code than AMDs. Even the high end AMDs are faster "on the paper".

Last but not least it can be that both gpus run at different PCI speed (count of lanes for data transfer). Alls complex CUDA + OpenCL apps are bond by transfer speed CPU GPU beside VRAM speed and gnu speed - and that of core isn't slow with AMD 4890 compared to 5xxx gnu.

same setup as before....rechecked hex edits...all okay!!!!

dont know!??!?!

 

!!!solved!!!

 

i forgot to edit AppleGraphicsPowerManagement.kext with correct device id!!!

 

ALL GOOD NOW!!!!thanx anyway ;-)

.

 

 

I did not know you could actually insert your Graphics ID into the Info.Plist. But what would be the values to enter <strings>? Did you just copy a set that was close to the same Device as yours and then just placed that section into the Info.plist?

 

Does this help prevent Kernel Panic or freezing of the screen? I just renamed it so I am not using it but if its better to have the device ID in there with the proper strings I rather do that than disabling that kext. I have to look for a thread on this.

I got this errors :D

Connecting to NVIDIA GeForce GTX 550 Ti...

Error opening file compute_kernels.cl

Segmentation fault: 11

Dont start the command line app by double click ! You must run it from the terminal & set directory to folder of the app before by cd
