Hi,
Last month I was able to capture BioShock Infinite without any problems, but testing it again today the game stutters when OBS is capturing the game (Game Capture). If OBS is closed it runs perfectly smooth but the second I open OBS and it hooks the game (even if I'm not recording, just previewing) the game starts stuttering.
This is on a clean install of Windows 10 (Creators Update), I had the same problem with DX9 games but OBS 18.0.2 fixed that.
Any ideas what might be causing this?
EDIT: here's a longer recording log if it's helpful:

The stuttering doesn't happen when capturing with alternative software, it does seem to be being caused by OBS.
