Hi @invalid,
in-game experience while using spacedesk depends on a lot of factors such as network connection, game settings, and your machine’s hardware/software specs.
there are a few things you can check and try.
1. Wi-Fi connections can be sensitive to various factors, such as distance or the number of connected devices, which can affect their performance. you might want to try using a wired connection for a much better performance.
please check the chapters under PERFORMANCE TUNING -> Use Direct Cable Connection on our user manual –

2. recalibrate your in-game settings and spacedesk viewer settings
3. make sure spacedesk driver and viewer are updated to the latest version
4. make sure your Graphics adapter is updated.
