Resolution Scaling Calculator
This static example shows what the calculator evaluates before you enter your own hardware.
Example inputs
2560×1440 · 75% render scale · 1920×1080 comparison
Calculated reading
1920×1080 internal render, about 2.07 million pixels—43.8% fewer pixels than native 1440p.
How to use it
Pixel ratio is not an FPS multiplier. Geometry shows the change in shaded pixels, while CPU limits, memory bandwidth, upscaler cost and game behavior affect the real frame-rate change.
Both dimensions are multiplied by the scale fraction. Their product gives rendered pixels; the result is compared with native and target pixel counts.
How to interpret the result
Pixel ratio is not an FPS multiplier. Geometry shows the change in shaded pixels, while CPU limits, memory bandwidth, upscaler cost and game behavior affect the real frame-rate change.
Calculation methodology
Both dimensions are multiplied by the scale fraction. Their product gives rendered pixels; the result is compared with native and target pixel counts.
The calculator runs in your browser from the values you select. Estimates use transparent planning rules and the site’s normalized hardware data; they are not lab benchmarks.
Formula or model used
Rendered pixels = width x height x (scale / 100)^2
Calculation steps
- Multiply width and height by the scale fraction.
- Calculate rendered and target pixel totals.
- Report percentage workload differences.
Assumptions and limitations
- Dynamic resolution and non-uniform upscalers can use different internal sizes.
- Pixel count alone does not model CPU work, ray tracing or memory bandwidth.
