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
Common in-game values: 50%, 75%, 100%. The internal render resolution as a % of native.
Result
Rendering at 75%
Native resolution1920 × 1080
Effective resolution1440 × 810
Effective pixel count1,166,400 px
Native pixel count2,073,600 px
Pixels saved vs native43.8%
Moderate GPU savings with mild quality loss.
