How to Configure OBS Scale Filtering to Point

When streaming or recording retro emulation games in OBS Studio, default scaling settings often make crisp pixel art look blurry and smudged. This guide provides a direct, step-by-step walkthrough on how to change your source’s Scale Filtering to “Point” (nearest-neighbor interpolation), instantly restoring the sharp, authentic pixel-perfect look of classic games.

Step-by-Step: Set Scale Filtering to Point in OBS

To remove the blur from your emulation capture, follow these steps:

1. Open OBS Studio and navigate to your active scene.
2. Go to the Sources dock and locate the capture source for your emulator (this is usually a Window Capture, Game Capture, or Display Capture).
3. Right-click on the emulator source.
4. Hover your cursor over Scale Filtering in the context menu.
5. Click on Point from the list of options (which also includes Bilinear, Bicubic, and Lanczos).

Once selected, your emulator source will instantly update in the preview window, replacing the fuzzy edges with sharp, distinct pixels.

Why “Point” Filtering Fixes Blurry Retro Games

By default, OBS Studio uses bilinear or bicubic scaling. These algorithms are designed to smooth out edges in modern 3D games and camera feeds to prevent jagged lines. However, when applied to low-resolution retro games (such as NES, SNES, or Sega Genesis titles), this smoothing effect results in a muddy, out-of-focus image.

“Point” filtering (also known as nearest-neighbor interpolation) scales the image by simply duplicating the existing pixels without blending them. This preserves the sharp, blocky aesthetic of pixel art, ensuring your stream or recording looks exactly like it would on a native CRT or high-quality pixel display.
