Yes i did delete the kext.
I had really decent 25 fps few days back before 10.7.3 update.
Today i did this update.
I just did put up test results ans they did not show the same numbers Sasha got.
This why i think something is wrong with cuda and / or setup generally.
I used CudaZ like on win.
Generally the same app that that has been mentioned here on the forum.
I will look into re installing separate cuda driver.
If any ideas please just shoot.
(OT:Also i made my own custom Y cable if enyone is interested i can put up picture of it.)
