On launching obduction I get a message saying " The global shader cache file /GlobalShaderCache-PCD3D_SM4 is missing"

and goes on to say Your application is built to load COOKED content. No COOKED content was found

I built my own tower it has:-
I FM4350 AMD 4 core 4.2Ghz processor
1 ssd 500Gb hard drive
1 sshd 1Tb hard drive
16Gb ram memmory
Asus strix Gtx 970 graphics card (not over clocked)
Corsair cx 750 psu
and a Asus M5A97 PLUS motherboard
Windows 8.1 pro os
an AOC 24" 144hz refresh gamimg moniter on a display port, AND logitech gaming mouse and keyboard

I must add i did use to play obduction when I first purchased it about a month ago but then disaster happened and i caught the zepto virus and had to format my drives and start again

This comes up if something is wrong with DX11 or you are missing DX11. I would uninstall/reinstall DX11 and hopefully that should fix your issue.

...and, as always, reinstalling the game as well, may solve your problem...

This error message indicates your system may not support the necessary graphics technology to run Obduction.
