Filters can also be re-ordered by dragging them up or down. Filters are applied

- *Downscaler*: Filter for downscaling the host resolution. Can be used to undo
poor upscaling on the VM to better utilize AMD FSR (see below). The filter
has a pixel-size setting that is used to set the effective downscaling ratio,
and a configurable interpolation algorithm.
- AMD FidelityFX Super Resolution (FSR): Spatial upscaling filter that works
- *AMD FidelityFX Super Resolution (FSR)*: Spatial upscaling filter that works
on low resolution frames from the guest VM and intelligently upscales to a

The DXGI capture interface also offers a feature that allows downsampling the
