What is your OS? And what graphics card do you have?

Windows 10 x64 rs5 17655 / GTX 760

That's a Kepler so theoretically OK with 397.31.

Not in real life

So it seems.

I'm having one issue so far. VirtualDub(2) crashes on exit in a cuda module.

Gonna revert the driver.

EDIT: 391.35 does not crash.

Give them a spin.

P.S: Just discovered that Windows + CTRL + Shift + B restart video driver.

Does that hotfix driver fix the original issue you had, i.e., crashing on exit in some apps?

Nope, just tried and same error when using DGSource.

Thanks for the testing. Fixed in slipstream 147.

You are always welcome.

What did they change, at the end?

It was my bug and a change in the driver exposed it. I was freeing some CUDA host memory in a thread without setting the correct CUDA context. Previously it apparently didn't matter. One might think that the address is sufficient, but it is not now true.

Still, nVidia should return a proper error and not crash.
