[@peter brooke] your recommendation of Resade.me, presumably a competitive offering, does absolutely nothing … as with most open source projects, it has no purpose but the uncommunicatable imagination of the programmers, who are unable to present any features, any benefits, any function.
Reshade is probably one of the best post-processing injectors out there, i guess you never really wanted to dive in into the subject, so you don’t know anything about it. But gamers actually do. Checking the forums would be a first start and reading about it, to make an informed decision.
