Hi!
Are there some major differences from NVinject and NVKush drivers? Performance/stability etc? Wich one would be best to choose for 7300GT and 10.5.5. and will the NVinject work with 10.5.5 at all?

Thank's

My experience is that none of the injectors work with 10.5.5; you have to use EFI strings.

I get full support QE and CI with either driver, dual displays works fine. Mirroring does not. Mirroring only works if one of the displays is rotated.

In my experience, after I updated from 10.5.4 to 10.5.5, NVinject and NVkush worked. I followed the instruction to use the GFX strings but what I got after that was a system with no QE support. So, I went back to NVinject and got QE back.
