  • Direct3D with YUV (default): This option offers optimal performance with reduced CPU load. When used alongside the Windows Streamer "Hardware" Captor, it can potentially enhance session FPS.
  • Direct3D with RGB: This alternative employs the RGB data format but may result in higher CPU usage than YUV.
  • SDL with YUV: If DirectX/Direct3D is disabled or not functioning correctly on your local machine, you can utilize this option. It also improves session performance during Session Recording.
  • Software: In case you encounter any issues with the other rendering options, you can select this alternative. It utilizes more CPU resources but tends to be compatible across multiple platforms.
