In3625207801I attempted to add non-breaking spaces to a filepath so it would stay on one line. Before this I had accidentally deleted my work but found it saved in my sphinx build cache, so I copied my changes from that cache. Unfortunately the cached version replaced non-breaking spaces with real spaces and3625207801was made reverted. This commit re-adds the non-breaking spaces.

|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
By default, Looking Glass uses the :kbd:`ScrLk` key as the escape key

.. _client_config_options_file:
|
|
|
|
Configuration files
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
By default, Looking Glass will load config files from
|
|
the following locations:
|
|
|
|
- ``/etc/looking-glass-client.ini``
|
|
- ``~/.looking-glass-client.ini``
|
|
- ``$XDG_CONFIG_HOME/looking-glass/client.ini`` (usually ``~/.config/looking-glass/client.ini``)
|
|
|
|
All config files are loaded in order. Duplicate entries override earlier ones.
|
|
This means you can set a system-wide configuration in
|
|
``/etc/looking-glass-client.ini``, and override specific options for just
|
|
your user in ``~/.looking-glass-client.ini``, which is overlayed on top of
|
|
the system-wide configuration.
|
|
|
|
When first launched, the Looking-Glass client will create the folder
|
|
``$XDG_CONFIG_HOME/looking-glass/`` if it does not yet exist.
|
|
|
|
The format of config files is the commonly known INI format, for example:
|
|
|
|
.. code-block:: ini
|
|
|
|
[win]
|
|
fullScreen=yes
|
|
|
|
[egl]
|
|
nvGain=1
|
|
|
|
; this is a comment
|
|
|
|
Command line arguments will override any options loaded from config
|
|
files.
|
|
|
|
.. _client_overlay_mode:
|
|
|
|
Overlay mode
|
|
~~~~~~~~~~~~
|
|
|
|
The Overlay Mode lets you configure various runtime options for Looking Glass.
|
|
These include:
|
|
|
|
- EGL filters
|
|
- Performance metrics options
|
|
- Debug frame damage display
|
|
|
|
(see :ref:`client_config_widget`)
|
|
|
|
You can also reposition and resize enabled widgets, like the FPS/UPS display,
|
|
and performance metrics.
|
|
|
|
Enter and exit Overlay Mode with :kbd:`ScrLk` + :kbd:`O`.
|
|
:kbd:`ESC` can also be used to exit. (see :ref:`client_key_bindings`)
|
|
|
|
Modifications done to widgets in overlay mode are stored in
|
|
``$XDG_CONFIG_HOME/looking-glass/imgui.ini``.
|
|
Please do not manually edit this file while Looking Glass is running,
|
|
as your changes may be discarded.
|
|
|
|
.. _client_config_widget:
|
|
|
|
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 Looking Glass at runtime.
|
|
|
|
Settings tab
|
|
^^^^^^^^^^^^
|
|
|
|
- *Performance Metrics*: A toggle for the performance metrics widget.
|
|
Multiple graphs are available, and they will stack vertically.
|
|
- *EGL*: Modify EGL settings, such as the algorithm used for scaling, and
|
|
night vision mode.
|
|
|
|
Changes in the settings tab are not persistent, and will be reset back to
|
|
their default values when the client is restarted.
|
|
|
|
EGL filters tab
|
|
^^^^^^^^^^^^^^^
|
|
|
|
The EGL filters tab contains options for toggling, configuring, and ordering
|
|
post-processing filters. Each filter can be expanded to open its settings.
|
|
Filters can also be re-ordered by dragging them up or down. Filters are applied
|
|
from top to bottom. Keep this in mind when ordering them -- for example,
|
|
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 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
|
|
on low resolution frames from the guest VM and intelligently upscales to a
|
|
higher resolution. The filter sharpness is tunable, and displays the
|
|
equivalent AMD quality mode based on the resolution difference.
|
|
|
|
- *AMD FidelityFX Contrast Adaptive Sharpening (CAS)*: Filter that
|
|
increases visual quality by applying a sharpening algorithm to the
|
|
video. CAS can sometimes restore detail lost in a typical upscaling
|
|
application. Has adjustable sharpness setting.
|
|
|
|
The filter settings and order can be saved to presets so that it can be restored
|
|
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 loaded 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.

Host usage
|
|
----------
|
|
|
|
By default the host application will simply work however there are some
|
|
configurable options available. While the host application will accept command
|
|
line arguments, it is more convenient to create a ``looking-glass-host.ini``
|
|
config file for persistent configuration changes.
|
|
|
|
This file must be placed in the same directory as the Looking Glass host, by
|
|
default ``C:\Program Files\Looking Glass (host)\``.
|
|
|
|
.. _host_capture:
|
|
|
|
Capture interface
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
.. note::
|
|
Currently we only provide support for the Windows host application, Linux
|
|
options are not currently documented.
|
|
|
|
Currently under windows there are two capture interfaces available for use,
|
|
by default the most compatible and commonly supported interface is selected
|
|
however this can be changed via the ini file with the following configuration:
|
|
|
|
.. code:: ini
|
|
|
|
[app]
|
|
capture=<INTERFACE>
|
|
|
|
Where ``<INTERFACE>`` is one of ``dxgi`` or ``nvfbc``
|
|
|
|
.. _host_capture_dxgi:
|
|
|
|
Microsoft DXGI Desktop Duplication
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
This interface (DXGI) is the default and most compatible capture interface for
|
|
windows, unfortunately though it does suffer from several drawbacks over other
|
|
options. DXGI capture can operate in two modes, DirectX 11 (default) or the
|
|
experimental and unofficial DirectX 12 mode.
|
|
|
|
Due to the design of Microsoft's DXGI API and the decision made to roll
|
|
hardware cursor updates into the capture stream this interface can suffer from
|
|
microstutters when the mouse is being moved/updated. This issue only affects
|
|
guest applications that make use of the hardware cursor instead of compositing
|
|
the cursor directly, as such titles that do not use a mouse (most FPV games)
|
|
are not affected.
|
|
|
|
The other drawback of this API is the overall system overhead, however this can
|
|
be mitigated by using the DirectX 12 backend. Please be aware though that this
|
|
backend is not experimental because its new, but rather it's a slight
|
|
abuse/misuse of the DXGI API and allows us to bypass some Windows internals.
|
|
|
|
To enable the DirectX 12 backend the following configuration needs to be added
|
|
to the ``looking-glass-host.ini`` configuration:
|
|
|
|
.. code:: ini
|
|
|
|
[app]
|
|
capture=dxgi
|
|
|
|
[dxgi]
|
|
copyBackend=d3d12
|
|
d3d12CopySleep=5
|
|
disableDamage=false
|
|
|
|
The option ``d3d12CopySleep`` is to work around the lack of locking this misuse
|
|
of the API allows and you will need to tune this value to what suits your
|
|
hardware best. The default value is 5ms as this should work for most, lowing
|
|
it below 2ms is doubtful to be of practical use to anyone. If this value is too
|
|
low you may see screen corruption which is usually most evident while dragging
|
|
a window around on the Windows desktop.
|
|
|
|
.. note::
|
|
Lowering d3d12CopySleep can improve the UPS however the UPS metric makes
|
|
little sense when using the d3d12 backend as if this value is too low
|
|
unchanged frames will be doubled up.
|
|

The ``disableDamage`` option may be needed to avoid screen corruption. Note
|
|
that this will increase the bandwidth required and in turn the overall load on
|
|
your system.
|
|
|
|
The DXGI capture interface also offers a feature that allows downsampling the
|
|
captured frames in the guest GPU before transferring them to shared memory.
|
|
This feature is very useful if you are super scaling for better picture quality
|
|
and wish to reduce system memory pressure.
|
|
|
|
The configuration for this is fairly straightforward and is defined as set of
|
|
rules to determine when to perform this downsampling. The format is as follows:
|
|
|
|
.. code:: ini
|
|
|
|
[dxgi]
|
|
downsample=RULE1,RULE2,RULE3
|
|
|
|
The rules are written as follows:
|
|
|
|
.. code::
|
|
|
|
(>|>=)(WIDTH)x(HEIGHT):(LEVEL)
|
|
|
|
The ``LEVEL`` is the fractional scale level where 1 = 50%, 2 = 25%, 3 = 12.5%.
|
|
|
|
**Examples:**
|
|
|
|
.. code:: ini
|
|
|
|
[dxgi]
|
|
; Downsample anything greater then 1920x1080 to 50% of its original size
|
|
downsample=>1920:1080:1
|
|
|
|
; Downsample exactly 1920x1080 to 25% of its original size, and anything greater
|
|
; then 1920x1080 to 50% of its original size.
|
|
downsample=1920x1080:1,>1920x1080:2
|
|
|
|
; Downsample anything greater or equal to 1920x1080 to 50% of its original size
|
|
downsample=>=1920x1080:1

NVIDIA Frame Buffer Capture
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Due to the NVIDIA SDK License agreement this GPU feature is only available on
|
|
professional/workstation GPUs such as the Quadro series. It is known however
|
|
that **all** NVIDIA GPUs are capable of this as both GeForce Experience and
|
|
Steam are able to make use of it.
|
|
|
|
If you are able to make use/enable this this feature it offers lower overall
|
|
system load and lower latency capture, and does not suffer from the mouse
|
|
motion stutter issues that DXGI suffers from.
|
|
|
|
To enable its usage use the following configuration in the
|
|
``looking-glass-host.ini`` file:
|
|
|
|
.. code:: ini
|
|
|
|
[app]
|
|
capture=nvfbc
|
|
|
|
If this feature is unavailable to you the host application will fail to start
|
|
and the host log will contain an error stating that the feature is not
|
|
available.
|
|
|
|
The NVFBC capture interface also offers a feature much like DXGI to allow
|
|
downsampling the captured frames in the guest GPU before transferring them to
|
|
shared memory. However unlike DXGI which is limited to fractional scaling,
|
|
NvFBC is able to scale to any arbitrary resolution.
|
|
|
|
The configuration for this is fairly straight forward and is defined as set of
|
|
rules to determine when to perform this downsampling. The format is as follows:
|
|
|
|
.. code:: ini
|
|
|
|
[nvfbc]
|
|
downsample=RULE1,RULE2,RULE3
|
|
|
|
The rules are written as follows:
|
|
|
|
.. code::
|
|
|
|
(>|>=)(WIDTH)x(HEIGHT):(TARGET WIDTH)x(TARGET HEIGHT)
|
|
|
|
**Examples:**
|
|
|
|
.. code:: ini
|
|
|
|
[nvfbc]
|
|
; Downsample exactly 3840x2160 to 1920x1080
|
|
downsample=3840x2160:1920x1080
|
|
|
|
; Downsample anything greater then 1920x1080 to 1920x1080
|
|
downsample=>1920x1080:1920x1080
|
|
|
|
; Downsample 3840x2160 to 1920x1080, or 3840x2400 to 1920x1200
|
|
downsample=3840x2160:1920x1080,3840x2400:1920x1200
|
|
|
|
This capture interface also looks for and reads the value of the system
|
|
environment variable ``NVFBC_PRIV_DATA`` if it has been set, documentation on
|
|
its usage however is unavailable.

Selecting an IVSHMEM device
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
For those attaching multiple IVSHMEM devices to their Virtual Machines, you must
|
|
configure the Looking Glass host to use the correct device. By default the first
|
|
device is selected.
|
|
|
|
The ``os:shmDevice`` option configures which device is used. These are ordered
|
|
by PCI slot and count up from 0 (default), with 0 being the first IVSHMEM device
|
|
in the lowest slot.
|
|
|
|
.. code:: ini
|
|
|
|
[os]
|
|
; Select the second IVSHMEM device
|
|
shmDevice=1
|
|
|
|
.. note::
|
|
``os:shmDevice`` ignores the actual PCI slot number, instead selecting the
|
|
*N*\th slot occupied by an IVSHMEM device. For example: with only two IVSHMEM
|
|
devices in slots 0x03 and 0x05, the device in slot 0x03 will be referred to
|
|
by *0* (first shm device), and the device in 0x05 by *1* (second shm device).
|
|
|
|
PCI slot numbers are visible in Device Manager:
|
|
|
|
1. Double-click any "IVSHMEM device" in Device Manager (``devmgmt.msc``)
|
|
2. Find the slot number in the "Location:" field. (e.g. PCI slot 5)
|
|
|
|
You can also find a listing of IVSHMEM devices in the ``looking-glass-host.txt``
|
|
log file, with slot numbers shown next to "device" (asterisk indicates currently
|
|
selected device)::
|
|
|
|
[I] 19989544 … IVSHMEM 0 on bus 0x6, device 0x3, function 0x0
|
|
[I] 19990438 … IVSHMEM 1* on bus 0x6, device 0x5, function 0x0
