After clicking Play Game on the launcher, Sanctus Reach proceeds to the intro.
This plays fine. However, after this has done the screen goes blank (black screen) with a blue circular loading mouse icon flashing.
If I click the mouse, press enter or esc, the screen begins to strobe flash and the programme stops responding.
I play through Steam. I have verified the files. De-installed and re-installed twice. All to no avail.
It would be greatly appreciated if you could provide some advice or ideally a fix

I have attached the dxdiag.txt file.
Again, any help you can provide is appreciated.
Kind Regards
Dale
