1. The version of Windows you are running has a limitation which causes performance issues in hardware accelerated applications (such as games) if multiple monitors with different refresh rates are present. Your system's monitors have 2 different refresh rates, so you are affected by this limitation.
To fix this issue, we recommend updating to the Windows 10 May 2020 Update. Follow
these instructions if you're not sure how to update.
2. Display and Game Capture Sources interfere with each other. Never put them in the same scene.
3. Multiple Game Capture sources are usually not needed, and can sometimes interfere with each other. You can use the same Game Capture for all your games! If you change games often, try out the hotkey mode, which lets you press a key to select your active game. If you play games in fullscreen, use 'Capture any fullscreen application' mode.
4. In Windows 10 versions 1809 and newer, we recommend that "Game Mode" be enabled for maximum gaming performance. Game Mode can be enabled via the Windows 10 "Settings" app, under Gaming > Game Mode
