Resolution Scaling Calculator

What does a 75% (or any %) render scale actually look like in pixels?

Render scaling draws the frame at a lower internal resolution, then upscales to your screen. Lower scaling = fewer pixels = more FPS, at some sharpness cost.

Inputs

Native resolution

Render scale (%)Common in-game values: 50%, 75%, 100%. The internal render resolution as a % of native.
