I just saw a news about HDMI cable with integrated uhm... post-processing with enhancements in games AA/sharpening or video quality, googled a bit and found this review
So okay... Long story short - but i have an idea - maybe you should
crowdfund something like this, i mean standalone semi-hardware version of Reshade where you can upload presets or at least adjust some settings. Maybe not so advanced as injector version (no depth buffer etc) but hey, if this non-configurable "cable" got a niche then maybe it's not a bad idea overall.

Also it can work in every game not matter of rendering mode.
What do you think, guys?
