NVIDIA GPU was working fine then i installed the latest update and it is not detected as a supported card anymore and NVENC is disabled
i am using window 10 in a Virtual machine on Proxmox with NVIDIA GRID P4-2Q vGPU card/driver (sometimes using the 4Q and other vGPU profiles) and all the other NVENC softwares installed are still working fine but after the update hybrid will not, ive tried downgrading and removing all traces but it just won't work.
is there any way to force it to load NVENC and tell it which card to use with a setting in the ini file in .hybrid or something?
Hybrid Log:
-> skipped 'Intel(R) HD Graphics 530' since it's no NVIDIA card
Detected the following cards which seem to lack NVIDIA PureVideo support: Intel(R) HD Graphics 530 Microsoft Basic Display Adapter NVIDIA GRID P4-2Q Microsoft Remote Display Adapter Red Hat VirtIO GPU DOD controller
No card found that's supported by nvenc, the CUDA encoding library. -> Removing CUDA based encoding support.
Thank you Selur for all your hard work on this software, it is my favorite encoder by far i use it for everything and it always does a better job vs others. its also the only one i can get to use both NVENC encoder and decoder at the same time to reduce CPU usage, you have done such an amazing job here. Please, read the 'Infos needed to fix&reproduce bugs,..'-sticky before you post about a problem.

No, there is no option to force Hybrid to assume card xy is compatible.
What does "NVEncC.exe --check-features" report in such a setup?
Cu Selur
Ps.: the cause isn't directly the installation of the newest release, but that after a reeinstall Hybrid checks for the gpu (triggering Config->Tools->Clear all cached tool info). My guess is the card was before reported as something else in the registry.

p.s. i think you are 100% right there i think that is exactly what has happened which not sure how but somehow it did, its just now not detecting it right, is there a key in the registry hybrid references i should change to fix it? host gpu is a tesla P4

Send you a link to a dev version which should detect the 'NVIDIA GRID P4-2Q' as a compatible card.
Try it and let me know whether it works.

i ended up getting a random QT error the first time that did not appear the second time and it detected the card perfectly and now is working just as it should, thank you for the help fixing that.

I'm experiencing similar issues too, not getting my Nvidia card ( NVIDIA RTX 3500 Ada Generation) recognized. Although I'm new to Hybrid so might be just missing something obvious...
Even forced Hybrid.exe to use the main GPU instead if Intel iGPU in the Windows 11 graphics settings (my Nvidia drivers don't have that feature in Nvidia Control Panel anymore)
Hybrid log says this:
-> skipped 'Intel(R) Iris(R) Xe Graphics' since it's no NVIDIA card
Detected the following cards which seem to lack NVIDIA PureVideo support: NVIDIA RTX 3500 Ada Generation Intel(R) Iris(R) Xe Graphics Microsoft Basic Display Adapter Microsoft Remote Display Adapter
No card found that's supported by nvenc, the CUDA encoding library. -> Removing CUDA based encoding support. Card name was compared against: https://developer.nvidia.com/cuda-gpus
and C:\Program Files\Hybrid\64bit\NVEncC.exe --check-features says this:

Uploaded a new dev version to the 'experimental'-folder of my GoogelDrive-share. (linked in the download section)
Try and let me know whether that version fixed the detection of the card.
If not, I'll look some more at it tomorrow. (on my way to bed now  )

Ps.: You didn't miss anything, Hybrid simply didn't know the card.

Got it. Now it seems to be working:
-> skipped 'Intel(R) Iris(R) Xe Graphics' since it's no NVIDIA card
Detected NVIDIA PureVideo compatible cards: NVIDIA RTX 3500
Thank you for the quick fix, and this awesome tool!
