Configuration Widget
~~~~~~~~~~~~~~~~~~~~
The Configuration Widget is accessible through the Overlay mode. The
widget has multiple tabs that allow setting a variety of modes and
parameters for the application.
Settings tab
^^^^^^^^^^^^
- Performance Metrics: Enabling this will turn on the Metrics Graphs
Widget. Multiple graphs can be enabled and they will stack vertically.
- EGL: Modify EGL features such as the algorithm used for scaling and
enabling night vision mode.
Changes in the Settings tab are not persistent and will change back to
their default values when the client is restarted.
EGL Filters tab
^^^^^^^^^^^^^^^
The EGL Filters tab is a GUI for enabling, configuring and ordering
the post-processing filter stack. Each filter can be expanded to open
its settings. Filters can also be re-ordered by dragging them up or down.
Filters application is cumulative, and order is important (e.g. applying CAS
before FSR might have different results than the reverse). Users are
encouraged to experiment with the order and parameters to achieve optimal
results. The currently available filters include:
- Downscaler: Filter for downscaling resolution. Can be used to undo the
poor upscaling that some games implement such that it can then
be better upscaled using FSR (see below). The filter has a pixel-size setting
that is used to set the effective downscaling ratio and can be set to use
different downscaling algorithms.
- AMD FidelityFX Super Resolution (FSR): Filter implementing a rendering
technique for upscaling resolution. FSR works by accepting the original
frames (on the guest) at lower resolution, then applying a spatial upscaling
algorithm in the client to make the final result look as though it is
rendered in high-resolution. The FSR filter interface allows for fine
tuning the sharpness factor of the algorithm and shows the equivalent
quality mode based on the ratio between the original frame resolution
and the client resolution.
- AMD FidelityFX Contrast Adaptive Sharpening (CAS): Filter that
increases visual quality by applying a sharpening algorithm to the
frame. CAS can sometimes restore detail lost in a typical upscaling
application. The CAS filter interface has an adjustable sharpness
control.
The filter stack settings and order can be saved to presets so that it
can be conveniently recalled at a later time. As filter settings are
usually application specific, multiple presets can be defined for each
case scenario. To save a preset, click on "Save preset as..." and enter
a preset name. Presets are recalled by selecting them in the "Preset name"
pull down. Presets are persistent and are stored on disk at
``$XDG_CONFIG_HOME/looking-glass/presets``.
.. warning::
Please refrain from modifying any files under the ``presets`` folder.
Those files are meant to be modified only by the Looking-Glass client.
.. note::
Although presets are persistent, the client will not remember which
preset was used last session, so a preset needs to be recalled once
the client starts.
