Under Windows this is an option in the AMD control panel. Not sure how to enable it.
Specifically, this is for a non-native Proton game with FSR support built in. I am not using GE as I need the latest code in Proton experimental to run this game.
Game is Hunt Showdown and they don’t have sharpening as an in game option.
I will take a look at vkBasalt. Little worried that could trigger a ban from their anti-cheat.
Yeah, don’t do that. You’re asking for the game to shut off at best. They probably won’t have the anticheat configured to outright ban you for that but, as a general rule: do not tamper with multiplayer anti-cheat protected games.
My recommendation would be to go to their discord and request the option.
EDIT: I will say this is overly cautious advice, I’ve never seen Crytek in general or any other developer ban people for using render alternating software that wasn’t specifically designed to be a cheat.
The game doesn’t even realise gamescope is there. That’s the beauty of it. As the game sees it, it’s just a regular monitor with the specs you gave it via commands
You can use gamescope. There are keyboard shortcuts to modify sharpen filter.
