gamescope's Introduction

gamescope: the micro-compositor formerly known as steamcompmgr

In an embedded session usecase, gamescope does the same thing as steamcompmgr, but with less extra copies and latency:

It's getting game frames through Wayland by way of Xwayland, so there's no copy within X itself before it gets the frame.
It can use DRM/KMS to directly flip game frames to the screen, even when stretching or when notifications are up, removing another copy.
When it does need to composite with the GPU, it does so with async Vulkan compute, meaning you get to see your frame quick even if the game already has the GPU busy with the next frame.

It also runs on top of a regular desktop, the 'nested' usecase steamcompmgr didn't support.

Because the game is running in its own personal Xwayland sandbox desktop, it can't interfere with your desktop and your desktop can't interfere with it.
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. This can be useful in exotic display configurations like ultrawide or multi-monitor setups that involve rotation.

It runs on Mesa + AMD or Intel, and could be made to run on other Mesa/DRM drivers with minimal work. AMD requires Mesa 20.3+, Intel requires Mesa 21.2+. For NVIDIA's proprietary driver, version 515.43.04+ is required (make sure the nvidia-drm.modeset=1 kernel parameter is set).

If running RadeonSI clients with older cards (GFX8 and below), currently have to set R600_DEBUG=nodcc, or corruption will be observed until the stack picks up DRM modifiers support.

Building

git submodule update --init
meson build/
ninja -C build/
build/gamescope -- <game>

Install with:

meson install -C build/ --skip-subprojects

Keyboard shortcuts

Super + F : Toggle fullscreen
Super + N : Toggle nearest neighbour filtering
Super + U : Toggle FSR upscaling
Super + Y : Toggle NIS upscaling
Super + I : Increase FSR sharpness by 1
Super + O : Decrease FSR sharpness by 1
Super + S : Take screenshot (currently goes to /tmp/gamescope_$DATE.png)

Examples

On any X11 or Wayland desktop, you can set the Steam launch arguments of your game as follows:

# Upscale a 720p game to 1440p with integer scaling
gamescope -h 720 -H 1440 -S integer -- %command%

# Limit a vsynced game to 30 FPS
gamescope -r 30 -- %command%

# Run the game at 1080p, but scale output to a fullscreen 3440×1440 pillarboxed ultrawide window
gamescope -w 1920 -h 1080 -W 3440 -H 1440 -b -- %command%

Options

See gamescope --help for a full list of options.

-W, -H: set the resolution used by gamescope. Resizing the gamescope window will update these settings. Ignored in embedded mode. If -H is specified but -W isn't, a 16:9 aspect ratio is assumed. Defaults to 1280×720.
-w, -h: set the resolution used by the game. If -h is specified but -w isn't, a 16:9 aspect ratio is assumed. Defaults to the values specified in -W and -H.
-r: set a frame-rate limit for the game. Specified in frames per second. Defaults to unlimited.
-o: set a frame-rate limit for the game when unfocused. Specified in frames per second. Defaults to unlimited.
-F fsr: use AMD FidelityFX™ Super Resolution 1.0 for upscaling
-F nis: use NVIDIA Image Scaling v1.0.3 for upscaling
-S integer: use integer scaling.
-S stretch: use stretch scaling, the game will fill the window. (e.g. 4:3 to 16:9)
-b: create a border-less window.
-f: create a full-screen window.

Reshade support

Gamescope supports a subset of Reshade effects/shaders using the --reshade-effect [path] and --reshade-technique-idx [idx] command line parameters.

This provides an easy way to do shader effects (ie. CRT shader, film grain, debugging HDR with histograms, etc) on top of whatever is being displayed in Gamescope without having to hook into the underlying process.

There is currently no way to set the value of uniforms/options, they will just be their initializer values currently.

Using Reshade effects will increase latency as there will be work performed on the general gfx + compute queue as opposed to only using the realtime async compute queue which can run in tandem with the game's gfx work.

Using Reshade effects is highly discouraged for doing simple transformations which can be achieved with LUTs/CTMs which are possible to do in the DC (Display Core) on AMDGPU at scanout time, or with the current regular async compute composite path. The looks system where you can specify your own 3D LUTs would be a better alternative for such transformations.

Pull requests for improving Reshade compatibility support are appreciated.

gamescope's Issues

Use host cursor in nested case

Hide nested cursor, go 1:1, etc.

exiting 'duke nukem 3d megaton edition (classic)' crashes xwayland

Steam Controller Wayland pointer input

Steam Controller can be used in two modes basically:

Mouse/keyboard emulation going through libinput (check libnput --list-devices)
Higher-level logic internal to the Steam-client.

Current issues:

In mode 1

Works in X11 sessions, but not in desktop Wayland sessions at the moment, tested on KWin Wayland, see for GNOME [1] and [2]. Apparently has worked in the past though (sure?). Interestingly a short test showed that it works in sway. Maybe the other compositors just don't support multiple pointer devices with different characteristic (i.e. different device groups etc.)?

In mode 2

Is activated once the Steam client starts up. Mode 1 gets deactivated at that point in time. Has some more gimmicks. But it uses XTestFakeRelativeMotionEvent for sending pointer motions to the OS. Changing the cursor position by that is currently not supported in XWayland (warping pointers is).

So even if problem of mode 1 is solved as soon as mode 2 is activated, i.e. the Steam compositor starts up, the pointer input should be broken in any current Wayland desktop session again.

In gamescope currently the compositor itself listens into the X11 connection to get the XTest induced cursor position. That blocks us from going Wayland-determined cursor-position only at the moment and leads to corner-case issues when the synchronization lags behind (mouse position only updated after first move, returns to last position where it was moved with mouse before controller etc.).

Solution ideas

Without changing the Steam-client internal code solutions could be:

For (2): support XTestFakeRelativeMotionEvent in XWayland.
...

Sometimes clients going away still take down the compositor

Not sure what's up yet

Assertion failed in page_flip_handler

Just ran gamescope -l -d -- xterm and kept the Enter key pressed. Likely caused by a race condition.

Get rid of EGL and GBM inside wlroots

We just want the dma-bufs, we hsould be able to bypass all that stuff with some wlroots work.

Get layers working consistently

libliftoff is hooked up with -l, and Roman has done some fixes already, but doesn't seem to work reliably still. Would be really nice to get that 100% robust on amdgpu so we could have the FPS meter or notifications up without killing perf.

Fix texel sampling locations for real

There's a 0.5 bias kludge in right now, but it won't do the exact right thing.

[Crusader Kings 2]Very slow in fullscreen mode with upscaling

Hi,
I launch CK2 on my second screen with 1440p upscaling with this command :
gamescope -w 2560 -h 1440 -W 1280 -H 720 -- %command%

The game works and it's fully playable if i stay in window mode. But if you enable fullscreen mode with Win+F, the game is really slow when a new game is loaded and during a party.

vainfo crashes if gamescope is running

it somehow detects a wayland compositor is running and tries connecting to it, even though i'm running it from a completely separate context without WAYLAND_DISPLAY set. how come?

SUMMARY: ThreadSanitizer: data race ../src/steamcompmgr.cpp:2277 in operator()
==================

`-r 30` stopped working

It used to be that passing -r 30 properly got vsynced clients like glxgears to meter themselves to 30fps, etc.

we still make the wlr_output_set_custom_mode() call with the nested refresh and nested xrandr still reports it, so how come it's getting ignored?

Screen 0: minimum 16 x 16, current 1280 x 720, maximum 32767 x 32767
XWAYLAND0 connected 1280x720+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1280x720      29.93*+

Add support for wp_viewporter

With swaywm/wlroots#2092 merged, gamescope can easily add support for the wp_viewporter protocol, allowing old games that expect to be able to perform modesets to work correctly.

Requires Xwayland master.

SUMMARY: ThreadSanitizer: data race ../src/steamcompmgr.cpp:2582 in steamcompmgr_main
==================

Plus a bunch of other races when cleaning up, but we're segfaulting anyway on shutdown.

GEM handles aren't closed

We call drmPrimeFDToHandle but we never close them. We should perform a DRM_IOCTL_GEM_CLOSE ioctl to do so.

However we need to implement some kind of refcounting: two DMA-BUF imports may yield the same GEM handle.

Tearing in embedded mode

On DC at least, sometimes there's crazy tearing. We know we need to import a fence, so not too unexpected, but you'd think implicit sync would take care of it.

touch position doesn't match when scaled

when using a touchscreen in embedded mode

Stuck in "performing first time setup"

Install Mirror's Edge
Run it from the first time in the embedded session
Installer is stuck on "performing first time setup"

The first time setup actually installs NVIDIA PhysX, which requires user interaction to accept the license. The embedded session doesn't show the license window and gets stuck forever.

Recent modifier-related activity in Mesa breaks us (further)

Usually we'd just have to set R600_DEBUG=nodcc to avoid format mismatch for OpenGL clients, but Vulkan clients would be fine. As of recent Mesa this is no longer the case and this commit has to be reverted for Vulkan clients to work:

https://gitlab.freedesktop.org/mesa/mesa/-/issues/2801

https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/4298

X-side synthetic input broken with latest commits

can be reproduced in nested:

./gamescope -e -- steam -tenfoot -steamos

Connect a Steam controller or any controller, launch Factorio or any game that uses the normal OS cursor, configure a mouse mode on the trackpad, observe that cursor doesn't move when mouse input is issues despite the game properly reacting to the X-side cursor position.

Get rid of forked wlroots subproject

Need to implement xwm-less wlroots for real and then we can just use upstream

Change README example for integer scaling to include -n flag

Looking at the code, and by visually inspecting, I see that -n flag is needed to enable integer scaling. But, this isn't included in the example command with integer scaling.

Implement vt-switching in the embedded case

Looks easy, get xkb_keysym_t from input, then if it XKB_KEY_XF86Switch_VT_* call wlr_session_change_vt(). xkb handles the Ctrl-Alt-F* chording for us.

Completely plumb modifiers across the stack and clean everything up

So we get optimal compression/performance across the board and stop having to disable RadeonSI DCC.

Mouse input in embedded doesn't work when grabbed

See Dragon Dogma

Zero copy when nested

Avoid copying buffers when running nested: directly hand over the game's DMA-BUF to the parent compositor.

Xwayland is delaying commits for vsynced clients

Looking at gpuvis captures for vsynced games running is xwayland, unwanted things are happening. Xwayland is decoupled from the thing actually handling the output, so I'm not sure it ought having a say. Ideally Xwayland would just forward whether the client wants vsync to the compositor, and the compositor could pass back enough information to have the right behavior instead.

Use high-priority compute

Right now if there's concurrenct graphics work our copy is significantly worse in terms of latency. Throughput might be better due to concurrency.

Fix frame cadence interaction with cursor repainting

We want to note we want to repaint next vblank, but not actually trigger a new frame just by moving the cursor. We just need to defer the decision until as close to vblank as possible, right now we're emitting twice the frames and getting behind if you're moving the cursor a bunch.

Commandline argument to start in fullscreen

-F probably?

Make it exit if/when nested command completes

Probably easy to track with spawn()?

Figure out why we're not always 'flipping' in Xwayland

Dragon Dogma has Xwayland rendering in the gfx pipe. Why? It needs to go.

DOOM Eternal black buffers in embedded

But is consistently fine for me on a desktop or nested. DOOM 2016 is fine too. Maybe Vega vs. Raven? Haven't tried nested on Raven, maybe good next step.

Get rid of Mesa hacks

We currently use private Mesa APIs:

https://github.com/Plagman/gamescope/blob/fc72bda2cfa1a9ee59147d69ed714b620a0c2e7d/src/rendervulkan.cpp#L112

Instead we should implement VK_EXT_image_drm_format_modifier in Mesa and use it in gamescope:

https://www.khronos.org/registry/vulkan/specs/1.2-extensions/man/html/VK_EXT_image_drm_format_modifier.html

Failed to find physical device on Intel

I'm trying to start gamescope (e.g. gamescope command without params), but then I get segfault with the following errors:

Any ideas?

In nested, imitate the client window more

Auto-size with their size, auto-fullscreen if they ask for it, etc. all optional

Maybe mirror the cursor and window title as well.

Starting XCOM Chimera Squad often crashes after the splash screen

Crash inside of the linked list for wlr_send_frame_done - weird.

Vulkan fence syncobj export is failing

Currently all commented out. Why is it failing? We need a sync fd to give DRM

Use wrap-git instead of submodules

https://mesonbuild.com/Wrap-dependency-system-manual.html#specific-to-vcsbased-wraps

Using *.wrap files would mean meson doesn't mysteriously fail if you didn't init the submodules. meson would just check them out for you. It also means if you only need one of them, you don't end up git submodule init/update'ing both.

You can use wrap-git to pin a commit or track master.

map_fbid_inflightflips race condition

drm->map_fbid_inflightflips is accessed from both steamcompmgr and page_flip_handler.

Gracefully handle drmModeAddFB failures

If the display engine doesn't support a buffer format, drmModeAddFB may fail. We need to properly fallback to composition in this case. Right now we have an assert( commit.fb_id != 0 ).

Stop using ALLOW_MODESET unconditionally

ALLOW_MODESET allows the driver to apply the new state with a visual glitch (e.g. black screen during 5 seconds). This isn't great while in the middle of a gaming session.

https://github.com/Plagman/gamescope/blob/453caf76728bd4bed9b3f293f97cdef173e3a2d3/src/drm.cpp#L796

Allow shortcuts to be configurable

Allow shortcuts to be configurable through a config file or something, as I have discovered to my dismay that my new keyboard doesn't have a Meta key. :(

Using system libraries for wlroots and libliftoff

Is it possible?

for emersion/libliftoff#40 I also asked for a release

Pointer constraints not working in embedded mode

Start any FPS in embedded mode
Camera goes crazy on any pointer move

Move to xres pid querying

Right now we're getting appids through the atom set by gameoverlayrenderer. It's not super robust and there's a bunch of cases where the current hooks don't set the Atom (like Dead Cells native) - getting the pid through xres 1.2 should be robust (see keithp recent commit in xrestop), and then we can walk up /proc/ until we find the SteamChildMontior, which would give us the appid reliably
