Hello. It seems like you don't have dx12 installed? Try updating your graphics driver, if you have Nvidia.

Hmm.. I'm pretty sure the video memory isn't enough.
Go to: C:\Users\"your name"\AppData\Local\FracturedMind\Saved\Config\Windows and open Settings.ini
Change the following settings:
sg.ResolutionQuality=from 100 to something like 65 for start
sg.ViewDistanceQuality= from 3 to 1
sg.ShadowQuality= from 3 to 1
sg.TextureQuality= from 3 to 1
sg.EffectsQuality= from 3 to 1
sg.FoliageQuality= from 3 to 1
r.setres= from 1920x1080f to 1360x768f
Give that a try. I'm not guaranteeing it will work, but it's worth a shot.
