Here are my specs:
CPU: 7800X3D
GPU: RX 7900 GRE
RAM: 32GB DDR5 6000mhz
Monitor: Alienware AW3423DWF OLED
OS: Fedora 40
DE: GNOME 46

Just wanted to share my experience: This is the first time I played through a game on Linux, and it worked better than on Windows (not even fanboying Linux, it’s just the truth).

I played the entire Elden Ring DLC on Linux with working HDR in Fedora GNOME 46 without gamescope. I thought gamescope was needed because I had tested HDR gaming on Plasma. But on GNOME, I just needed the DXVK_HDR=1 launch parameter and set up HDR by doing the following:

  1. Press ALT + F2
  2. Type lg and press enter
  3. Enter the following command to activate HDR: global.compositor.backend.get_monitor_manager().experimental_hdr = 'on'

Then, I just start Elden Ring and activate HDR in the in-game settings, and it works.

On Windows, while playing in HDR, tabbing out is really annoying because it takes 2 to 3 seconds to switch out when I want to use the browser or Discord for something. But on GNOME/Linux, I just press Super and navigate with the mouse or use Super + Mouse wheel or any other shortcut.

HDR gaming on Linux doesn’t work with an Nvidia GPU, though. I had an RTX 4070 Ti Super before, and it didn’t work at all, not even in a standalone gamescope session.

So, I am ready to use Linux full-time since I am also a software engineer and only keep Windows on a fourth SSD for games like League or Valorant or other games my friends are playing.

Soon, I will switch to Arch Linux with KDE Plasma 6. Finally, my dream came true.
