OBS worked fine some time ago (aabout a week ago) then the issue started appearing from seemingly nowhere. No new programs installed, no program/windows updates, no setting changes nothing.
The problam is with the final recording. It seems to have framerate issues. Note that it's fine at the beginning of the recording the problem is noticeable from around 10 sec in and then gets progressively worse.
I fixed the problem erlier by uninstalling OBS and reinstalling it, everything seemed to be good until recently when the problem reappeared, again seemingly from nowhere.
Will probably try to fix it again by reinstalling. But I'm seeing a pattern here and it would kind of suck to have to reinstall OBS once every week.
Also there where no framerate issues in game had around 280 constantly, and yes I have a max fps limit set.
