Blurry/Grainy graphics and lag on every setting

[TheMorgzilla]

I've played the first episode and I'm on the second one now, but throughout the whole thing the graphics look really grainy and there will be facial glitches (especially on max) no matter what settings I have it on. I've also noticed some parts (mainly bright area cutscenes) there will be quite a bit of lag. It seems really tempermental, like one minute the game will look and run incredibly and then the next minute it will look horrific.

I've adjusted the resolution scale to just over half way, I've changed the secondary scale to 100.
I've turned vertical synchronization off but that makes things look worse.
Turned motion blur off and I've put post process quality to low and I've had the rest of my settings on either medium or high but even on low the problems still exist.

I'm confused as I understand my computer isn't anything spectacular but I am able to play a lot of other games on highest quality, especially the other life is strange games.

Any suggestions??
