Game suffers lag spikes if it was NOT started before starting OBS (everything works perfect if started the other way round)

So this is not related to streaming or recording itself. Those things work just fine.
But I have very bad lag spikes in games if the game was started after launching OBS. If I start the game first and OBS afterwards, everything works just fine.
And before you anyone asks. DVR, Shadowplay, Game Bar etc is all disabled. I am running out of ideas what the root cause could be.
I can stable reproduce this just by launching OBS. No streaming, no recording.
Has anyone seen this behavior before and maybe got a hint what I could check for?
