Controller Plug And Play Enabled
When ticked, vMix supports detecting when MIDI and X-Keys controllers are plugged in / unplugged while
vMix is running.
Performance
Graphics Adapter
This is for selecting the graphics card vMix will use on systems with multiple graphics cards installed.
For best performance this should match the graphics card that monitor displaying the vMix interface is
attached to.
For laptops with hybrid graphics (also known as Optimus), only the graphics card selected in the Nvidia
control panel
will be visible here. In this case, you can instead control Integrated or Dedicated graphics use in vMix from
the Nvidia control panel, or equivalent control panel
if using a different graphics card vendor.
Low Latency Capture
This will reduce the latency of Camera inputs by approximately one frame.
This will substantially increase the load on the graphics card and may lead to dropped frames under heavy
load, so it should used with caution.
High Input Performance Mode
If you plan on using a large number of cameras (typically > 8) and a large number of inputs, performance
can be improved by ticking this checkbox.
Note that this only works on graphics cards with a large amount of built in memory (3GB+) and will result in
poor performance if enabled on graphics cards with less memory, or Intel graphics.
Disable Windows Update while vMix is running
Windows Update may automatically install updates to the computer in the background at any time.
This option will disable Windows Update while vMix is running in order to avoid any potential performance
drops as a result of windows installing updates during a production.
Display Method
This option selects the method by which vMix presents video to the computer display (both for Preview/
Output windows and the Fullscreen outputs).
Note that these options do not impact the recording / stream / external outputs in any way, and only apply
to the outputs on the graphics card.
Auto Let vMix select the best option based on the current settings. This will usually be the same as
selecting Low Latency for frame rates less than 30 and Smooth otherwise.
Low Latency Displays video as fast as possible to the computer display to ensure the lowest possibly
latency. Video playback may be less than smooth as a result.
Smooth vMix will make every effort to ensure the video playback is as smooth as possible on the display
but may add a couple of frames of delay as a result.
Legacy Use the display method employed by vMix 20 and earlier.
