 anji | By the way I've also had success when running Wayland by using GE-Proton and PROTON_ENABLE_WAYLAND=1 PROTON_ENABLE_HDR=1 ENABLE_HDR_WSI=1 %command% as command. This also seems to be the rare combination which makes HDR work on some Proton games. | 14:08:50 |
 niklaskorz | fyi you don't need ENABLE_HDR_WSI with up to date drivers anymore | 14:23:42 |
| niklaskorz | Mesa 25+ (for AMD and Intel) or Nvidia 595+ | 14:24:01 |
| anji | I needed it otherwise tonemapping in several games was wrong. Typical "washed out" colors. On NixOS stable with Plasma. | 14:26:32 |
| niklaskorz | what drivers are you on? | 14:29:30 |
| niklaskorz | if it's Nvidia then likely 580 | 14:29:42 |
| niklaskorz | 26.05 will default to 595 so you can remove the hdr layer then | 14:30:14 |
| niklaskorz | * 26.05 will default to 595 so you can remove the hdr layer when updating in two months | 14:30:44 |
| anji | I'm on AMD with whatever is current on 25.11. Mesa 25.2 or something. | 14:31:31 |
| niklaskorz | hm then you shouldn't need the layer at all | 14:31:53 |
 K900 | NixOS stable may need the layer | 14:32:20 |
| K900 | As it's a fairly old Mesa | 14:32:25 |
| K900 | And also somewhat old Plasma | 14:32:30 |
| K900 | But yes, things should be significantly better on unstable | 14:32:47 |
| K900 | (and you generally want to be running unstable if you're doing gaming anyway) | 14:33:00 |
| niklaskorz | Mesa has the required protocols since 25.1 though 🤔 | 14:33:03 |
| niklaskorz | not sure about Plasma though | 14:33:36 |
| anji | Yeah it's not "out of the box" yet but I can get HDR to work now in all games. With either the commandline above, or gamescope. Which is neat. | 14:34:22 |
| anji | With 26.05 perhaps it will work out of the box? I look forward to trying it out. | 14:35:07 |
| niklaskorz | actually that makes me wonder what happened to the drop VK HDR layer PR | 14:36:05 |
| niklaskorz | ah it's still open | 14:36:54 |
| niklaskorz | https://github.com/NixOS/nixpkgs/pull/496305 | 14:36:55 |
| anji | btw I'm on stable mostly because of power management. I suspend/resume this machine all the time and I've had really good experiences with stable. A little less so with unstable at times. And I feel like the gaming experience on stable is excellent too. Just lagging behind a bit of course | 14:40:05 |
| anji | Thanks for all the work you do btw K900. NixOS is great for KDE and gaming :) | 14:40:36 |
| K900 | That is very strange because stable and unstable have the same kernel versions | 14:41:04 |
| K900 | And suspend/resume is predominantly a kernel thing | 14:41:17 |
| anji | Oh they do? I didn't actually notice that. Another misconception of mine busted | 14:42:12 |
| K900 | Well stable defaults to whatever LTS was at time of release | 14:43:34 |
| K900 | And unstable tracks latest LTS by default | 14:43:40 |
| K900 | But if you're tracking linux_latest, and you should be if you're gaming, it will be approximately equal | 14:43:57 |
