Modern games let you set a render scale or resolution scale below or above your display resolution to trade sharpness for frame rate, and this calculator shows exactly what that percentage does to the pixels your GPU must draw. Enter your native width and height and a scale percentage, and it returns the actual internal render width and height, the total pixels at both native and scaled resolution, and the percentage change in pixel workload. Since GPU cost roughly tracks pixel count, dropping from 100 to 80 percent scale can cut the pixel load by more than a third, which explains the frame rate boost. Going above 100 percent supersamples for extra clarity at a steep cost. Seeing the real numbers helps you pick a scale that balances image quality and performance for your hardware. All math runs locally in your browser with nothing sent anywhere, so dial in the render scale that fits your rig.
