Dynamic Resolution Rendering
DRR is an algorithm that aims to increase and smoothen
game performance by trying to keep a fixed displayed render target resolution, but dynamically
varies the resolution that is driving the engine shading.
One of the primary issues inhibiting adoption of DRR is the modification to post-processing
pipelines that it requires. With the introduction of DirectX 12 and placed resources we are
introducing an updated algorithm implementation that removes the need for most, if not all,
post-processing pipeline modifications at the cost of increasing your memory requirements with
an additional dynamic resolution render target buffer.
