Work out resolution scaling instantly with clear inputs, formula shown and shareable results.
Render scale multiplies both dimensions, so total pixels and therefore GPU load scale with the square of the percentage. A 150% render scale means 2.25 times the pixels, which is why supersampling costs far more performance than the percentage suggests.
Scaled dimensions
new dimension = base dimension x render scale
Pixel load
pixel ratio = render scale squared
new dimension = base dimension x render scale. Render scale multiplies both dimensions, so total pixels and therefore GPU load scale with the square of the percentage.
A 150% render scale means 2.25 times the pixels, which is why supersampling costs far more performance than the percentage suggests.
Enter base width, base height, render scale. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
