| 30 | + | Creating a gamescope window on the terminal and attaching the game to it will work, but HDR will be broken. | |
| 30 | 31 | ||
| 31 | 32 | First I run this on a terminal: | |
| 32 | 33 | ||
| 33 | 34 | ```sh | |
| 34 | - | gamescope -W 3840 -H 2160 -r 165 --hdr-enabled --hdr-itm-enable --hdr-itm-sdr-nits 300 -f --mangoapp | |

| 38 | 40 | ||
| 39 | 41 | ```sh | |
| 40 | 42 | DISPLAY=:x gamemoderun %command% | |
| 41 | 43 | ``` | |
| 42 | 44 | ||
| 43 | - | Where `x` is the display number, shown on the gamescope terminal output, example: | |
| 44 | - | ||
| 45 | - | `wlserver: [xwayland/server.c:107] Starting Xwayland on :2` | |
| 46 | - | ||
| 47 | - | In this case, the launch option would be `DISPLAY=:2` | |
| 48 | - | ||
| 49 | - | The game might take a while to open up and also to completely exit, but it works just fine. | |
| 50 | - | ||
| 51 | - | ### mangohud and --mangoapp | |
| 52 | - | ||
| 53 | - | Running it as `mangohud` before `%command%` will show GPU info but not gamemode, and apparently there are issues running it this way. | |
| 54 | - | ||
| 55 | - | I have to investigate if I have these supposed issues, and if they are related to any config about vsync and/or framerate locks on mangohud. | |

| 57 | - | ### Game freezing | |
| 45 | + | Where `x` is the display number. The game might take a while to open up and also to completely exit, | |
| 46 | + | but it works just fine, except for HDR. | |
| 58 | 47 | ||
| 59 | - | Possibly due to HDR flags but I'm not certain. Needs a reboot for the game to open again. | |
| 48 | + | Apparently this is needed for HDR to work this way: https://github.com/Zamundaaa/VK_hdr_layer, | |
| 49 | + | and adding `ENABLE_GAMESCOPE_WSI=1 DXVK_HDR=1` on the game's launch parameters, before `gamemoderun` | |
| 60 | 50 | ||
| 61 | - | I haven't had this issue in a while, might've been fixed in an update, might've been something I did. | |
| 51 | + | ### mangohud and --mangoapp | |
| 62 | 52 | ||
| 63 | - | ### Performance | |
| 53 | + | It is recommended to run `--mangoapp` if using gamescope, however it won't display any GPU info. | |
| 54 | + | Running it as `mangohud` before `%command%` will show GPU info, but might have some other issues down the line. | |
| 55 | + | On both ways, information like HDR, FSR, gamemoderun status won't be displayed at all. | |
| 64 | 56 | ||
| 65 | - | Have to set the niceness of gamescope. Run: | |
| 57 | + | ### Crashes and freezes | |
| 66 | 58 | ||
| 67 | - | ```sh | |
| 68 | - | sudo setcap 'CAP_SYS_NICE=eip' $(which gamescope)` | |
| 69 | - | ``` | |
| 59 | + | From time to time xwayland will crash in many ways. | |
| 60 | + | When there's a lot going on in my games and performance might be taking a hit, the game and Steam will simply close immediately. | |
| 61 | + | This is the softest of the crashes because I can simply reopen Steam and the game without issues. | |
| 70 | 62 | ||
| 71 | - | It seems that after a while it loses its niceness, so I made a systemd service that runs on login | |
| 63 | + | Sometimes the game will freeze or my entire desktop will freeze (this one also happens randomly when I'm dragging a window or starting a game). | |
| 64 | + | I have to restart my PC in this case. | |
| 72 | 65 | ||
| 73 | - | checking if the niceness is set, and setting it if it's not. Check the [gamescope-niceness.service](gamescope-niceness.service) gist | |
| 66 | + | There are some bug reports about these issues on bugs.kde.org, gamescope GitHub, NVIDIA drivers GitHub and forums, | |
| 67 | + | but no one knows why or how it happens, and many times it's hard to get logs. If you happen to have these issues and can provide logs or useful information, | |
| 68 | + | please do so on the proper channels. | |
| 74 | 69 | ||
| 75 | - | ### Placebo flags | |
| 76 | - | ||
| 77 | - | `-W -H -w -h -f -b` don't have any effect. I can freely change my resolution and fullscreen settings ingame and it'll work just fine. | |
| 70 | + | ### Performance | |
| 78 | 71 | ||
| 79 | - | Reading gamescope's readme, it mentions: | |
| 72 | + | When you run gamescope, you might notice on the terminal something like | |
| 73 | + | ||
| 74 | + | `No CAP_SYS_NICE, falling back to regular-priority compute and threads. Performance will be affected.` | |
| 80 | 75 | ||
| 81 | - | > You can spoof a virtual screen with a desired resolution and refresh rate as the only thing the game sees, and control/resize the output as needed. | |
| 82 | - | > | |
| 83 | - | > This can be useful in exotic display configurations like ultrawide or multi-monitor setups that involve rotation. | |
| 76 | + | Performance WILL be affected. After a while, your game will look like a slideshow, but your frame counter will still display the FPS as normal. | |
| 77 | + | ||
| 78 | + | That means you have to set the niceness of gamescope. Run, as *sudo*: | |
| 84 | 79 | ||
| 85 | - | Probably I can run the game on a lower resolution without impacting my desktop's resolution and use the FSR flags to upscale it. Maybe I can even downscale the game? | |
| 80 | + | ```sh | |
| 81 | + | setcap 'CAP_SYS_NICE=eip' $(which gamescope)` | |
| 82 | + | ``` | |
| 86 | 83 | ||
| 87 | - | `-r` seems funky though. Sometimes not setting it will lock the game to 60FPS, sometimes it has no effect at all. | |
| 84 | + | It seems that after a while it loses its niceness, so I made a systemd service that runs on login, | |
| 85 | + | checking if the niceness is set, and setting it if it's not. Check the `01.gamescope-niceness.service` | |
| 88 | 86 | ||
| 89 | - | There's also a flag to limit the max FPS but it doesn't do anything, or a setting on mangohud might be conflicting with both flags. | |
| 87 | + | ### VRR | |
| 88 | + | ||
| 89 | + | VRR (adaptive sync, GSYNC) will **not** work on NVIDIA cards if you have more than one monitor enabled. There are no solutions, no workarounds, | |
| 90 | + | and I don't think NVIDIA has even recognised this issue. | |
| 91 | + | ||
| 92 | + | While this is not a problem related to gamescope, mangohud or gamemoderun, I've added this section because it might come in handy. | |
| 93 | + | ||
| 94 | + | By disabling any extra monitor, VRR will work again. I've made the `02.start-gamescope.sh` script to be run as a launch parameter on the game, | |
| 95 | + | it'll start a gamescope window, turn off my extra display and start the game with gamemoderun and connecting it to the window. | |
| 96 | + | When quitting the game, the script turns the extra monitor back on and properly disposes of the gamescope window. | |

| 24 | + | ||
| 25 | + | [GitHub issue](https://github.com/ValveSoftware/gamescope/issues/835) | |
| 26 | + | ||
| 27 | + | Creating a gamescope window on the terminal and attaching the game to it will work. | |
| 28 | + | ||
| 29 | + | First I run this on a terminal: | |

| 34 | + | ||
| 35 | + | Then set the game's launch options: | |
| 36 | + | ||
| 37 | + | ```sh | |
| 38 | + | DISPLAY=:x gamemoderun %command% | |
| 39 | + | ``` | |
| 40 | + | ||
| 41 | + | Where `x` is the display number, shown on the gamescope terminal output. | |
| 42 | + | ||
| 43 | + | The game might take a while to open up and also to completely exit, but it works just fine. | |
| 44 | + | ||
| 45 | + | ### mangohud and --mangoapp | |

| 54 | + | ||
| 55 | + | I haven't had this issue in a while, might've been fixed in an update, might've been something I did. | |
| 56 | + | ||
| 57 | + | ### Performance | |
| 58 | + | ||
| 59 | + | Have to set the niceness of gamescope. Run: | |
