Graphics Adapter


This displays the graphics card vMix is using 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 NVIDIA Optimus), the graphics card shown here can only be changed from the NVIDIA control panel. It cannot be selected or changed from within vMix directly.


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.
