In the quest for more clarity of image in Oculus Rift VC1 I did some google sleuthing and found this:
Long story short, the debug tool is already installed per the ed forum thread post, so don't bother trying to install any SDK's, it's unnecessary.
Change the "Pixels Per Display Pixel Override" parameter from 0 to 2 and hit enter (you know it's set when your 2 changes to 2.000000)
I recycled the Oculus software that starts up automatically, and rechecked the debugger to confirm it was set to 2.
I did immediately notice improvement in E:D and the A-10C. Much less fuzzy.
I will test some more after GoT.
