Can't record with NVENC after the new update. Any fix?

[PossibleTango]

After the new update I can't record with Shadowplay or OBS with NVENC. I have a 3090. Is there a fix for this? With shadowplay it just instantly stops recording.

I tried reverting all my drivers but unfortuately it's permanently broken, is there any fix?

Most likely a driver issue... looks like old drivers. If you can't update your driver, you may need to use DDU to completely remove your GPU driver installation. Be sure to follow the directions carefully.

Considering shadowplay also doesn't work, this is not an OBS issue but a problem to be brought up with Nvidia support.

I tried that but it unfortuntely did not work. I contact nvidia support, hopefully they help but there customer support in my experience has been lacking.

The maximum resolution with Nvenc is 4096x4096. You try to encode a video with 5120x1440.
This is no OBS limit, it's a limit of the nvenc circuit on the GPU.
Lower the output resolution and it will work fine.

It works, thanks. But why would it allow me to record in 5120x1440 before the new update is what's got me curious. Whatever. Thanks.

If you're really curious, try to look into older logfiles with actual recording sessions, from before the update. Do you have older logfiles laying around? OBS keeps the last 10 logfiles, so they might be already gone, if you started OBS frequently since the update. Do Help->Logfiles->Show Logfiles and look through the logfiles starting with the oldest. Near the top you see the OBS version, and somewhere in the middle you will find any recording sessions you made, including the encoder that was used.

I suspect you either used a different encoder or didn't use 5120x1440 as output resolution. You might have used this as canvas resolution (which isn't relevant for nvenc), but perhaps not as output resolution (which is relevant for nvenc).
