Supported games and engines
Second Screen Gaming works on a game while it runs, so what it can do depends on how the game was built.
By engine
What each engine gets
| Engine | Fix | Notes |
|---|---|---|
| Source and Source 2 | Configuration | Background audio and simulation are console variables, written to autoexec.cfg. The most reliable case. |
| Unreal Engine 4 and 5 | Configuration, usually | Settings in the game's Engine.ini. Unreal asks Windows which window is in front instead of believing activation messages, so the focus assist cannot stand in for it. |
| Unity | Focus assist | Run In Background is compiled into the game, so the focus assist answers focus changes instead. |
| SDL2 | First-click fix | Makes the click that focuses the game count. Steam needs one restart to pass the setting to its games. |
| Godot | Rarely needed | Godot does not mute or pause on focus loss by default. |
| Any other game | Runtime assists | The borderless fit and the throttle exemption work on any game with a normal window. The focus assist works on engines that believe the activation messages Windows sends. |
Anti-cheat
Games with anti-cheat
When Second Screen Gaming detects anti-cheat in a game, it switches off the runtime assists, and it never tries to disable or get around anti-cheat. The borderless fit only moves and resizes the game's window, the way Windows itself does, so it stays available, and so do configuration fixes.
Detection is not a guarantee. Before using any tool with an online game, check that game's terms.
By game
Tested games
Each game gets its own page once it has been tested: every fix that was tried, whether it worked, and the date and game version of the test. Nothing is listed on a guess.
Until a game has its page, the table above is the best guide. The app shows which fixes a running game can take before you turn anything on, and says why when one cannot work.
