NVENC / VCENC

[Selur]

Whats the equivalent of step 2 on windows?

Those two tools are Windows only,.... so that is already what you do on a Windows machine.
Open a Windows Command Prompt and call something like:

"C:\Program Files\Hybrid\64bit\NVEncC.exe" --check-features

(with adjusted path and tool name)

for NVEncC:
-------------------
Starting with NVEncC 4.51:

Update to NVENC SDK 9.1, now NVIDIA graphics driver 436.15 or later is required.

see: https://github.com/rigaya/NVEnc/releases/tag/4.51

If your card is too old to have 436.15 or later drivers your only ways out are:
a. switch to a newer card
b. download an older version of NVEncC (download NVEncC_XXX_x64.7z) extract it in the 64bit folder of Hybrid and rename the NVEncC64.exe to NVEncC.exe .
c. don't use NVEnc
