Hi all,
I have an HDR capable monitor, HDR enabled in KDE plasma, but I still can't get some games to let me switch on the HDR toggle. Every time I turn it on in the game, it says something along the lines of "your hardware must support HDR" or some shit like that. After some online searching, I was able to enable it on ONE game in the heroic games launcher with (I think) a launch command? Where I threw there a "--HDR" and some other strings in there after enabling gamescope (this is where shit starts to confuse the hell out of me), then the game let me actually toggle HDR on. I can never do that on Steam. I am trying to play Indiana Jones and the great circle and it says the same. Same with Resident evil 4.
How do you do it? Is there a guide or something to follow? Is it like per game? Like some games allow it and others don't? Also, and most importantly, how the hell does gamescope work? On heroic, there are things like "Game width, game height, upscale width and upscale height". On Lutris, there is a cleaner way with dropdown menus where you choose a "Output resolution" and a "Game resolution" resolutions. What are those? Which is which?
Sorry for the very long post, and I appreciate any help
Thank you
Thank you so much. This is what I needed. Does this enable HDR on the game in general, or does it enable the toggle for HDR in the game? Also, do I need the Wayland parameter if I'm already on Wayland?
The wayland parameter is needed yes. This runs proton natively in wayland and not in xwayland which is the default. This feature is not available in the regular proton versions at the moment but it is in Glorious Eggrolls
I have HDR enabled on my monitor but still have to enable HDR in each game where it’s supported.
From what I’ve heard the colour management is still a bit hit and miss between OS and window managers but my experience has been good so far.
Thank you. I've saved your original comment for future reference
It will just make sure Proton tells the game your display supports HDR, you'll probably still need to enable it in game, unless the game uses it by default.
The Wayland flag tells Proton to use Wayland natively instead of xwayland, so you do still need it.
Awesome. Thank you so much.
Not the original, but from my experience, I believe this enabled the toggle which tells the game that you support HDR, proton then picks up the HDR signal and displays it, the rest is on your display.
Awesome. Appreciate the reply. I've found that there is a toggle for HDR on lutris that gets enabled when I flip the gamescope switch. And it stays active even after disabling gamescope. Now heroic needs to do the same.
