Does it support Vulkan? The DirectX backend is a lot faster than OpenGL under Windows.

No. There's a profiler in the logger that shows timings, I haven't looked at them awhile. What's the difference in performance?

A lot. Using DirectX on this laptop gives me 1080p recording at 60 FPS, and doesn't clog up the UI. Using OpenGL only yields 20 FPS, and slows down the UI.

You can't really measure in FPS unfortunately. I also wouldn't use OpenGL on Windows. That said, I don't remember such a large difference though I guess it depends on what you put in your scenes. I would post on their forum with your log.

I would love to see an option to use nearest neighbor for scaling of inputs, as it would make a lot of sense when dealing with low resolution content. It seems that this feature was requested back in the OBS days, but I haven't found if anyone even requested it for obs-studio.

Recording via Xcomposite + VAAPI costs ~10% performance here. It's not great, but it's bearable for some occasions.
When encoding on Polaris, the captured video has broken performance. But probably not OBS' fault, as it works with the Skylake IGP. That being said, I'm happy that they have improved capture compatibility with this version, e.g. in Heroes of the Storm.

Though I wished the VAAPI plugin would offer more encoder options (preferably all offered by ffmpeg).
