I'm on Windows 10 pro with a GeForce 1070 Ti and latest 436.48 drivers.

NVEncC 4.52 and DGIndexNV 2053.0.0.189 both work fine, but since the NVEncC 4.51 stated 'Update to NVENC SDK 9.1, now NVIDIA graphics driver 436.15 or later is required' I wonder if this is a driver vs. API issue.


-> Anyone else experiencing this? Or is this just my machine?
Any idea how to fix this?

I tried the latest build from zeranoe (20191013-4f4334b) and a build I compiled on my machine using MBAS.
I deinstalled and reinstalled the NVIDIA drivers.

I didn't look too closely but it probably has to do with the syntax change regarding -refs 3

see this
