Yup,checked the instructions several times. It took a while to get it to successfully run, thanks to my AV being a pain. Got that sorted, and can either use the injector exe or GUI and the game runs. I've ensured that motion blur is
on, Chromatic Abomination is
off, and SMAA is to T1x. The game runs and it's still like a flea circus, even at 3440x1440.
Now, I do have some things set in nvidia inspector, and is to force Max performance, GSync, Fast Sync, and ambient occlusion. I also have a few tweaks to the engine XML file to get higer LOD, better planar reflections, and better shadows. I'll reset everything and try again tonight.
Looking forward to trying the Unpredictable Alien mod and telling the girlfriend to have a go
