Technical dictionary for this analysis:

- AMD FidelityFX™ Super Resolution (FSR):

FidelityFX Super Resolution (FSR) is used to upsample an input image into a higher resolution. There are two versions of FSR with distinctive upscaling technique and image quality.

FSR 1 is a spatial upscaler based on the Lanczos algorithm* requiring an anti aliased lower resolution image.

FSR 2 is a temporal upscaler based on a modified Lanczos* requiring an aliased lower resolution image and utilising the temporal data (such as motion vectors and frame history) and then applies its own anti aliasing pass which replaces the game's temporal anti-aliasing solution.

Quality Preset Scale Factor Render Scale
Performance 2.0x 50.0% (e.g. for 4k: 1080p upscale to 2160p with FSR)
Balanced 1.7x 58.8% (e.g. for 4k: 1270p upscale to 2160p with FSR)
Quality 1.5x 66.6% (e.g. for 4k: 1440p upscale to 2160p with FSR)

* The Lanczos algorithm is an iterative algorithm invented by Cornelius Lanczos that is an adaptation of power methods to find eigenvalues and eigenvectors of a square matrix or the singular value decomposition of a rectangular matrix. It is particularly useful for finding decompositions of very large sparse matrices.


- Screen Space Reflections (SSR):

Screen space reflections (SSR): a more expensive technique that traces reflection rays in screen space (as opposed to world space in e.g. ray tracing). This is done for each rendered pixel of the reflected surface, using the surface normal and scene depth.
The disadvantage is that objects not captured in the rendered frame cannot appear in the reflections, which results in unresolved intersections and incomplete reflection image.


- Soft Shadows Mapping

Soft shadows are typically rendered in games by using shadow mapping and Percentage Closer Filtering with a uniform kernel size. The Percentage-Closer Soft Shadows (PCSS) algorithm computes a variable kernel size based on the distance between the relative position of the receiver point, an approximation of the blocker, and the area light.
