Creare Videogiochi - Game Developer

The Dynamic Resolution Rendering sample demonstrates a technique for dynamically adjusting the resolution of the main rendering, with graphical user interface components drawn at the native resolution. This technique can help developers achieve their quality and performance goals on a wide range of hardware and scene profiles. The sample also shows how the addition of scaling filters such as velocity aware temporal spatial anti-aliasing can enhance quality.

A view of the swinging bell with supersampling enabled and dynamic resolution control set to give 30FPS. The geometric temporal anti-aliasing uses velocity aware filtering to reduce ghosting artefacts.

With dynamic resolution parts of the scene with higher performance can have increased resolutions, yet match the chosen performance criteria. Geometric temporal anti-aliasing gives additional smoothness to the edges.
