init_cuda_ctx....... invalid device ordinal

[Calamon]

To be honest I may have broke something for changed a setting unintentionally yesterday. Trying to improve a games performance. This morning while trying to stream live I got this error. I have been streaming fine for 2 months and this error seems familiar or one close to it but I can recall how to fix it.

init_cuda_ctx: CUDA call "cu->cuDeviceGet(&device, gpu)" failed with CUDA_ERROR_INVALID_DEVICE (101): invalid device ordinal

Now trying to find a fix I did see it was asked for a log report so I will attach it here. Can anyone see what I missed? I even updated my Navidia drivers again.

The logs ends & the encode settings are missing but the wrong GPU is selected. It appears you are using the Advanced Mode, look at your encoder settings & make sure GPU is set to 0 & not 1 or something else.

I just started getting this same error. It doesn't matter if my device is set to 0 or 1. I have two graphics cards, and for the past 2 weeks, it has been working just fine with the 2nd graphics card. Now I can't go live at all.

Just started getting this error again and I'm on OBS 31.0.3 and there is no longer any setting for selecting the GPU.

Have you found a solution? Maybe the difference is in the stable/unstable version obs?

I have 5080 + 5060 Ti and have same issue, but I can’t reproduce an error, it occurs by accident. I know that on Windows 11 when using streaming + record, GPU load goes 100% and encode 60 - 80. On windows 10 gpu load 0% (encode 60%). This error occurred when I recorded the video, without stream. Maybe the question is in vendors?
