Video Settings in RetroArch

Video settings in RetroArch can be found under the Settings / Video section.

Here are some settings that may be helpful when using DOSBox Pure:

  • Scaling
    • Integer Scaling — It’s best to set this to ON to ensure sharp, clean pixels.
    • Aspect Ratio — Select Core Provided. This allows DBP to use the aspect ratio most suitable for the game being run.
  • Fullscreen Mode
    • Start in Fullscreen Mode — Enabling this will make RetroArch start in fullscreen mode by default.
  • Windowed Mode
    • Windowed Scale — Specify the scaling factor for windowed mode.
    • Maximum Window Width / Height — Set the maximum window size. When auto-scaling is used, the window will not exceed these dimensions.

Note on Scaling

The scaling settings in RetroArch (Windowed Scale) work together with the 3D scaling settings in DOSBox Pure. For example, if you set scaling to 2x in RetroArch and 3x in DOSBox Pure, the image will ultimately be scaled by 6x — DOSBox renders the 3D scene at a higher resolution, and RetroArch further scales the resulting image.

This concludes the overview of RetroArch settings. Next, proceed to installing DOSBox Pure.
