Bug Report obsnvenc.dll crashing on 1440p output

[Line40]

Not sure if this is really an OBS issue, maybe it's nvenc itself, but since the crash is in obsnvenc.dll I thought I'd report it here.

When I use nvenc, and set the resolution in OBS to 2560x1440, obsnvenc.dll crashes. The obs log and crash log are attached.

Hi

Some Info to add: It seems to really be an OBS issue, I downloaded RTSS 6.1.0RC, and could record 2560x1440 with it ok using nvenc.

I tried to reproduce this without any luck:

22:16:11: NVENC internal init finished successfully
22:16:11: NVENC supports 7 h264 presets

22:16:19: Encoder closed
22:16:19: NVENC deinitialized

Does it crash immediately or after a set amount of time? Any other hints you could give so I can reproduce this?

I tried to reproduce the crash, but it does not happen here anymore too.

Just for reference, I was using Black Mesa started from Steam, and there was MSI Afterburner 3.0.18 + RTSS 6.1.0 RC running in the background. That was also the scenario I used to try to reproduce the behaviour. I have added an Nvidia driver systeminfo report for reference.

Since I have experimented a lot with recording software lately, it may have been that it was an issue with another, DirectX hooking software or something. Although I think I changed nothing relevant :)

If I can get it to crash again, I'll report back here.
