FH4 PC tire smoke has distinct "straight lines" in it

Hey guys, I’ve search for a solution to this issue and nothing has helped so far.
I’ve been getting into the photography side of FH4 quite a bit lately and I really enjoy action shots (mainly dirft shots).
But I’ve noticed with the tire smoke there are lines through out it, example below

I’ve changed my video settings a few times and nothing seems to change.
I’d like to fix this issue as I want to minimise putting photos through photoshop afterwards as much as possible, it’s a simple fix in photoshop but I’m hoping to enter a few photocomps in the future once I get a good grasp on taking good quality photos, and as far as I know any editing in photoshop is prohibited.

I’m running the game on ultra if that helps at all.

Thank you in advance
