Thanks for your reply Dan,
Actually my interest in this game goes back to when you created a reddit page for the Hit a year or so ago, and posted on there with suggestions etc and after a while it seemed the game was dead, so was glad to know you are still working on it as its a great idea and the scope you are going for. I believe you are a one man band on this project so understandable there are somethings that you haven't had a lot of time to catch up on.
My PC Specs:
CPU: AMD 8320 8 Core @3.5ghz , 64bit, Win 10, 8 gb Ram, Nvidia Geforce 1060 graphics card.
This is what it looks like. Also notice the skybox looks fine. It flickers as you move.
On a side note, i think your game could have some graphic modes, like Black and White (like a b&w movie style- maybe some film grain texture filter layer on top like Mass Effect did in their early games) and a mode where it looks neon cyberpunk just for something different or someone mods the game with a cyberpunk flavour..
