As I already answered on SETI main, no changes in VLAR (kill) situation.
You will process all other tasks just faster.

For only CUDA crunching and best performance, PhysX ON/OFF ?
Over the system tray icon from nVIDIA.. right click -> performance and quality setting / system performance -> I can choose:
* high performance
* performance
* quality
* high quality
Stock is 'quality'.
How should be the setting for best CUDA performance?

I'm not one of the team but...
PhysX doesn't affect crunching... leave it on or off it doesn't matter for performance however with it on you shouldn't need to put a load (monitor or dummy plug) on a video card to use it (in theory)
High performance may give a very small boost but the best bet is to not have the screen displaying anything at all (in other words use the blank screen saver and not using the PC)

Now that the task list is turned on again...
They are valid!
So looking at the improvements I'm seeing about 10 credits a minute. (8.8 for a 92 credit task and 12.46 for a 29.08 credit task)
So 14000 RAC possible with a single GTX260core216

Strange is that they are in Completed, waiting for validation state, not invalid ?!¿¡

Drat! I put them in the BOINC folder. It's fixed now. I wasn't paying attention again :)
