Black undergrowth in recorded video

[Psyko]

I'm hoping you guys can offer some advice.

I'm getting some black artifacting, in my videos. I use OBS to record, and the first few videos i did of PR were fine, but after a week of recording, the videos started to degrade.

There arent any strange effects in other games like rainbow six siege.

Please take a look and tell me what you think. You can see it on the mountains in the background. I was advised to delete my cache, but that didnt seem to change the outcome.

Might be me, but I don't see any black undergrowth.
