Noticed this a bit on reddit etc recently so wanted a topic where we could play with it. Reshade takes presets and injects them into a running game, allowing you to do all sorts of effects and improvements. It’s the sort of thing that makes games like GTA look like photos.
Here’s a link to an OpenVR Sharpener shader, to help with clarity.
So you just download the zip, and then unzip the contents in the game run location to try, so something like
DCS World OpenBeta\bin should might work. Reshade uses the End key by default to toggle it on or off. The theory is it might be ok to go down in resolution (and get better performance in VR) but use something like this to make it clear again. The ReShadePreset.ini lets you play with brightness, color contrast, amount to sharpen etc as well. The algorithm is the well known AMD CAS (which is usually used with TAA) but I guess it’s all good. If there’s one thing we probably learnt from VR is that the proof is in the pudding and not the algorithm.
EDIT: It is IC friendly.
If you are going to give a go, then check out Reshade in VR - #53 by fearlessfrog for a set of updated shader files that run nicer.
