## Summary
Automatic controller assignment for Eden, aimed at couch co-op and handheld PCs (Steam Deck,
Legion Go, ROG Ally, AYN Odin), plus a set of fixes for running Eden in Steam's Game Mode
(gamescope) and under Steam Input.
## Controller Assignment Handler
Settings > Controls gains a **Controllers** tab. The handler is a segmented choice:
| Handler | Behaviour |
|---|---|
| **Modern Console** | Automatic: each controller that connects becomes the next player (up to 8). |
| **Manual** (default) | Players are set in each player's tab, as before. Its Controller Applet choice: **Disabled**, **Custom Frontend** or **Real Hardware** (the console's own applet, LLE). |
Under Modern Console, **Portable Handheld Gaming Device with Built-in Controller** (on/off)
makes external controllers take the players first, with the handheld's own controls used only
when none is connected.
In the automatic modes:
- Players follow their controllers across reconnects: a controller that leaves keeps its player
for 45 seconds and takes it back when it returns. Each controller keeps its own mappings when
it changes player, for the session.
- At most eight players; a ninth controller waits until a player is free.
- The user's saved controller setup is never rewritten; remaps made in the Controls tab last for
the session, and input profiles are what persist.
- Input profiles can be picked or removed per player, from the Controllers tab or each player tab.
- A controller whose player has no controller mappings (a fresh setup) gets its default mapping.
A DSU (cemuhook) motion binding from the manual setup is kept, for handhelds whose own gyro
needs it.
## Gameplay options
- **Pause When a Controller Disconnects** (on by default): the game pauses when a player's
controller is turned off, or has been gone for 3 seconds, and resumes when a controller takes
that player again. Pressing + on another controller goes on without it.
- **Use Any Controller as Joy-Cons**: a game that only takes Joy-Cons gets them automatically
(dual, or a single sideways one with the buttons arranged to fit).
- **Button Layout**: By Position or By Label, for Xbox and PlayStation style controllers.
- **Player Lights**: controllers that have them show their player number.
## Controllers tab and player tabs
- Connected Players: each player with its controller and battery, profile picker, Swap, Config,
Turn Off (Bluetooth), reorder arrows, drag to swap, and click to rumble. Controllers can be
given a name for the session.
- Assign Handheld Controller: auto-detect, or pick/Identify the handheld's own pad.
- P1-P8 tabs show each player's battery and can be dragged or moved with arrows to change the
player order.
- In Modern Console the Controllers and player tabs use a modern card layout that follows the
light and dark themes, including the system's dark mode (macOS).
## On-screen display
- **Controller Overlay** (View menu, Ctrl+Shift+V): players, their controllers and batteries,
and each player's recent buttons, including stick moves (LS/RS) and clicks (L3/R3). How many
inputs are kept and for how long can be set.
- **Controller Hints**: names a controller in the bottom-left corner when it joins or leaves
a player, and says when the game pauses for a disconnected one. Works without the overlay.
Both are drawn into the presented frame as crisp overlay panels (not scaled with the game, not
in screenshots), so they show inside gamescope.
## Steam Input and gamescope fixes
- **Native gyro under Steam Input.** Steam's virtual pads carry no motion sensors. Eden now opens
the real motion-capable controller behind each virtual pad for its sensors only (Steam Deck,
Steam Controller incl. the 2026 model, Sony, Nintendo), and turns on the Deck's IMU, which
Steam keeps off unless the layout uses the gyro. No DSU server or Steam layout change needed.
- **Bypass Steam Input** (Controllers tab, shown when launched through Steam): Eden opens the
real controllers itself instead of Steam's virtual pads.
- **Controller identity under Steam.** All virtual pads share one GUID and Steam moves physical
controllers between them; controllers are tracked by their Steam handle and slot instead.
- **Handheld detection under Steam.** The Deck's own controls are recognised behind Steam Input
without mistaking standalone controllers (e.g. the Steam Controller) for them.
- **Windows no longer rescale on hover in Game Mode.** gamescope scales a window to fit the
screen together with any tooltip reaching past it, so the main window and Settings grew and
shrank on hover. Under gamescope they now fill the screen.
- **VSync modes in Game Mode.** gamescope offers only some present modes, so Immediate and FIFO
Relaxed vanished silently. They are now listed greyed out with a tooltip pointing to Steam's
Disable Frame Limit and Allow Tearing settings.
- **Stick range testers on small screens.** The controller drawing scales down to fit on
800-pixel screens instead of cutting off the stick range circles.
- **Midnight Blue themes.** A hovered menu-bar item is readable again, and hovered tabs no longer
change size (which made the Settings tabs shake).
## Fixes
- Crash when HID received a controller update before NPad's applet resource was set up.
## Testing
Tested on a Steam Deck (Desktop and Game Mode, direct and Steam launches) with Xbox
controllers, plus a stress test with up to 10 virtual controllers connecting, disconnecting and
pressing at random in both automatic modes (no assignment errors, never more than 8 players,
disconnect pauses resume as expected).
## AI disclosure
Developed with Claude Opus 5.5 (implementation and debugging). I reviewed, tested and can

-------------------
Small good simplification to nuke a toggle which costed me almost an entire day of work when fixing controller applet issues:
There were two settings related to Controller applet:
-"disable controller applet", which is a boolean toggle;
-"controller configuration" applet mode, which is a "Real"/"Custom" picker;
All i did was to nuke the toggle and add a third option "Disabled" to the picker.
Users which used the disable toggle will have to pick Disabled;
Real/Custom settings wont be affected since their indexes remains.
All options tested against diablo 3. All working as intended.

This insufferable work tries to cover some holes on previous threading implementation from yuzu's team, starting with Windows and Linux reordering of priorities (NICE), reworks previous Android's threading and cpu affinity with adpf, adjust emulated clocks/gpu for better "accuracy" with their work, bumps android minSDK for all flavors, legacy will now work with AP 29 to cover A10 - A12, standard will reach A13 as base and finally the optimized build will come with API 35, mostly targeted on devices with A15 support and newer, NDK and AGP wasn't upgraded yet. The performance cost efficiency have been improved based on device power configuration; preventing overheating if certain devices tended to fall into NICE0 (not allocated threads priority, all task ran with higher priority, 11 tasks running within the limited 2 - 7 threads available on the most common configuration 1x3x4 or 1x4x3).

This simplifies the GPU accuracy setting by removing the intermediate Balanced mode and setting High as the default on desktop platforms.
It introduces a dedicated setting for GPU fence behavior, allowing the synchronization policy to be configured independently of GPU accuracy.
The Vulkan buffer cache now tracks GPU recording timeline ticks and waits only when necessary, reducing unnecessary synchronization while maintaining correctness for hard-to-trace graphical bugs.
GPU buffer readback has also been refined to synchronize only the affected upload regions when needed, and default DMA behavior has been updated to align with the new GPU accuracy model.
### TL;DR
The fix for particles freezing and unfreezing in mid-air in `Super Mario Odyssey` has been improved, resulting in less of a performance hit.
This game requires the new `Enable GPU Buffer Readback` option to be enabled to fix this issue.
The vertex explosions that occurred in `Super Mario Bros. Wonder`, especially in World 4, have been completely eliminated. You can now enjoy a smooth experience without graphical glitches exploding across the screen.
This game requires the new `GPU Fence Behavior` option to be set to `Strict` to fully fix this issue.
The flickering issue inside certain Shrines in `The Legend of Zelda: Tears of the Kingdom` has also been fixed.
For now, this game requires the new `GPU Fence Behavior` option to be set to `Accurate` to fully fix this issue.
These options are intended to fix graphical bugs in games that require better synchronization behavior between CPU and GPU, so other games may be affected as well.

Since the launch of the steam controller I think it's only best to push towards updating to SDL3 allowing for a wider range of controller support
I went ahead and started on getting it working. Everything here should be functional, I've personally tested it all on Arch Linux. Still untested on windows, so looking for feedback on that
Any feedback and help would be appreciated!
Main changes:
- Bump everything to SDL3
- Handle SDL3 audio and input
- Add steam controller support, including HD Rumble
- Improved battery reporting via the status icon by using real % rather than state alone

Closes#3344
Adds slow and turbo modes with configurable speeds that can then be
toggled by the user. Behavior is:
- Standard/slow limit, toggle turbo = turbo
- Turbo limit, toggle turbo = standard
- Standard/turbo limit, toggle slow = slow
- Slow limit, toggle slow = standard
Enabling the turbo/slow mode enables the frame limiter unconditionally.
This has some conflicts with VSync. For example when I set my refresh
rate to 60hz and enable vsync, turbo mode does nothing. Not sure how to
go about fixing this, @MaranBr probably knows better the proper
solution.

Basic impl of a grid view on the game list. The ideal solution here
would be to use QSortFilterProxyModel and abstract the game list model
out to a QStandardItemModel, but that is too much effort for me rn.
Adapted the "card" design from QML, can 1000% be improved but QPainter
is just such a pain to deal with. Implanting a Qt Quick scene into there
would legitimately be easier.
Anyways, margins and text sizes lgtm at all sizes, though please give
feedback on both that and the general card design.
Future TODOs:
- [ ] Auto size mode
- [ ] Refactor to use models

Since Android is a pain when it comes to checking GPU logs in more depth, this is a better way to see what's going on, especially for testers...
This should be expanded to Mali, Xclipse, and Tensor in the future. Since I don't own any of these devices, it's up to developers with similar capabilities to add support for this system.
~~The GPU log sharing button should also be added in the future... For now, they are available in the same location as the traditional logs.~~ Added on 572810e022

The GPU Accuracy level is now divided into Performance, Balanced and Accurate.
1. Performance prioritizes speed at all costs. It's faster, but it can be unstable and may have some bugs (which is expected).
2. Balanced maintains excellent performance and is safer against bugs and shader corruption.
3. Accurate is the most precise and the most expensive in terms of hardware. Only a few games still need this level to work properly.
The Release Early Fences toggle has also been removed by @PavelBARABANOV, as it's not needed anymore.
