Bug Report OBS video stutters after Windows 10 upgrade

[rakgitarmen]

Hello everyone,

I recently made the switch to Windows 10, but I'm having a lot of problems with OBS after doing so. I'm on a laptop with an Nvidia 840M and Intel 4600 working in tandem. I was using OBS Studio without any problems on Windows 8.1 before, with the same settings.

My problem is that my local video captures turn out to be very stuttery with a lot of duplicated frames in the files. I just can't get a smooth video, whereas I'm getting great FPS in my games. I'm using Quicksync but X264 makes no difference either.

Here's my log: https://gist.github.com/anonymous/ce71b6b75c645605eed1

The ONLY solution is enabling Multiple Adapter Compatibility in the source settings, but I lose a lot of FPS while doing so and it makes the game unplayable.

To my surprise, I installed MSI Afterburner to cross-check and it captures perfectly using the Quicksync encoder without any noticeable FPS loss. Here's a comparison:

MSI Afterburner: https://www.youtube.com/watch?v=4Yv6kPNOEYk
OBS without multi-adapter: https://www.youtube.com/watch?v=06YWUQ9VjGg

What I've tried so far:

1. Updating my drivers to latest (especially Nvidia and Intel)
2. Running games in Windows 8 compatibility mode
3. Running OBS in Windows 8 compatibility mode.
4. Trying different encoders.
5. Obviously OBS and the game is running on the same adapter.

I don't mind using MSI Afterburner instead of OBS, but I'd also like to be able to stream games occasionally and I like OBS a lot more.

Any help is appreciated. I think I've tried everything I can think of.

Try setting the priority of OBS higher in task manager, and also check to make sure you're using the 64 bit version

OBS uses the Quicksync implementation of Microsoft's Media Foundation, which isn't all that great.
What were the results with NVENC?
