Displaces is NOT an double click to start benchmark! Read the usage in the first post!
You must first start terminal, set working directory by cd to main folder of the bench, then start the bench in the terminal. Otherwise bench fails, because it cant find any of the needed files (.pfm,....)

893 Gigaflops (81920 stars) :superman:

You can try to set even more stars (run much slower but more Gigaflops on very fast cards possible).
You used 81920 , you can try 262144 star count also. Not recommended for slow / low end gpus - may stall OpenGL output / run out of VRAM.

For me OpenCL is not working and my card is not being recognized either as an OpenCL device...

I have a Quadro 5000 and it's working pretty well OOB, tried to find the hex string to patch it under ML, but the string has changed, so I don't know where to patch the file.

I didnt have to patch anything under ML for OpenCL - it just worked (GTX570)

Managed to get 10 Gflops more in ML (863) vs Lion (853), GPU settings/framebuffer same on both, ML on SSD while Lion install fills more than half of 2x1TB HDs in RAID-0, and a lot more stuff running in background/startup on Lion might explain the difference.

Nun, Galaxies startet gleich im GPU Mode, also SIM: Grafikkartennamen.
Mit key s kann man in den CPU mode umschalten.
Wenn Galaxies nicht im GPU Mode startet sondern im CPU MODE, dann klappt was mit OpenCL bei dir nicht.
Funzen denn die anderen OpenCL Benches (Luxmark2 oder OpenCLWeave)?

galaxies starts up in gpu mode by default. If galaxies starts up in an cpu mode (single/multi thread) then something is wrong with the OpenCL device gpu.
Try other OpenCL Benches.

PS: Have you tried to switch with key s between Cpu single / cpu multi and gpu ? What happens ? Never gpu shown as device ?

Try an new BUILD compiled under 10.7 / BUILD for 10.7.
For me both BUILDS working 10.7.3 + 10.7.4 : this test build today and the other (10.7+10.8) from first page on Nvidia 9600 GT - and getting same GigaFlops (138).
Dont use command line 80K Stars! Simple start galxies without changing star cont , so it can use 65K (default)!
May even also not work on some GPUs. Dont worry, until other OpenCL Benches like Luxmark 2.0 or OpenCL_Oceanwave work on your GPU.

...that build also a no-go here...on 10.7.3...still runs fine on 10.7.2
