Slower CUDA performance with the latest nVidia drivers 353.62

[Zakkorn]

After the issue with the FallOff I use this list more often.
Thanks though

I checked the latest nvidia drivers 355.60 and the CUDA performance became slower.
From 1:31 (353.62) -> 1:39 (355.60) on a Titan X
I reverted back to 353.62 and the score returned to 1:31 as well
I don't understand, are they trying to make the non Quadro cards, perform worse on professional applications?

No, I just think they are tinkering with the drivers a lot in the past few months. We've never seen so many issues and peformance differences as we've had lately. They are changing something in the drivers, but I don't know what.

Among other things I'm sure, I know they are adding the support of the oculus straight into the driver so oculus can bye pass all the software layer between the apps and the OS/hardware.

That's why when they will release 0.7 sdk, non of the previous coded apps will no longer be supported as they change radically the way the oculus is supported by the OS.

Maybe this has nothing to do, but we never know

Maybe they start working on the pascal integration as well, that will change a lot how GC are linked on the MB as they will introduce 8 x SLI and NVLink...
