Low frame rate issue

Hi all.
Struggling to get my graphic settings right. I’ve got a high end PC however my frame rate is really slow.
It did run very smoothly for a while but after an update the low frame rate issue began.
Anyone have any suggestions or ideas I could try to solve this issue?

Thanks lads

Low frame rate issues are frustrating and can ruin your gaming experience. Low frame rate is the frequency at which images appear on a display. To resolve this issue you can change the graphics preference for each app in Windows 10 to make sure it uses the dedicated graphics card instead of the integrated one.
