Poor performance in Synthetik 2

Hi all,

I'm having very poor performance in both menus (~24fps) and game (~15fps),

Changing graphics settings and resolutions does nothing to improve the frame rate,

Has anyone else had a similar issue or has any advice?

System: i7-8086K CPU @ 4.00GHz, GTX 1080ti, 32GB RAM, game is installed on an M.2
