Question / Help GTX 660 no NVENC capable devices found

[Nardella]

I used to be able to record lossless with NVENC on my PC with a GTX 660, but it doesn't work anymore. Please help!

fatal: No NVENC capable devices found
[NVENC encoder: 'recording_h264'] Failed to open NVENC codec: Generic error in an external library

Your card doesn't support lossless. https://developer.nvidia.com/video-encode-decode-gpu-support-matrix

Do you happen to know what the indistinguishable settings are, I need some of the advanced settings but everything I can think to try ends up with encoding lag despite indistinguishable working in simple mode.

Take a logfile with a session you created in simple mode/indistinguishable settings and scroll to the entries that correspond to the session start. You will see the actual encoder settings OBS was using in this mode.

Not all the settings appear to be there, or they have names I don't understand, could you please help me interpret the log file, my best interpretation fails.

From your logfile:
16:36:38.402: [jim-nvenc: 'simple_h264_recording'] settings: 16:36:38.402: rate_control: CQP 16:36:38.402: bitrate: 0 16:36:38.402: cqp: 16 16:36:38.402: keyint: 250 16:36:38.402: preset: hq 16:36:38.402: profile: high 16:36:38.402: width: 1920 16:36:38.402: height: 1080 16:36:38.402: 2-pass: false 16:36:38.402: b-frames: 2 16:36:38.402: lookahead: false 16:36:38.402: psycho_aq: true
How it should look like if you copy this to advanced recording mode:

Thanks! Turns out that simple was recording to C and advanced was recording to an external drive on USB 2.0.
