Performance Tweaking Guide

This guide explains which settings can greatly impact the playout performance of PIXERA.


Output Settings

One of the biggest influences on performance is the output settings. Specifying 30 fps on the actual GPU output brings a massive performance gain compared to 60 fps.

It is important that these are actually applied to the GPU output in Nvidia, otherwise we will not achieve most of the gain here. Even if 30 fps content is used on a 60 fps output, there is still a massive performance loss.

Tip

In some cases the EDID from the Output device will not give you a for example 30 fps option, in many cases you can still use 30 fps for the output if you create a custom resolution inside the Nvidia settings. EDID Management 

 

Video Codec

The codec has a significant impact on hardware performance. We generally recommend Notch LC as codec, as it offers the best balance between quality and performance.
More details: Supported File Formats - Codecs 

The worst performing codecs are usually those which are compressed the most. H264, H265.


Video FPS

When a 60 fps video is played back at 30 fps output, this generates unnecessary compute overhead, resulting in unnecessary loss of performance.

Try to stick to the defined output frame rate.
In some cases, it can improve performance if you deactivate the “Blend Frames” option. Clip Speed and Blend Frames 


Screen Groups and “Render only on Home Screen”

Screen groups and render only on home screen have a major impact as they determine which client has to render which content. The default settings in Pixera ensure that everything ends up in one screen group and all layers are rendered on all screens. In a multi-client setup, this means that they are distributed to all clients and loaded there even if they are not displayed if not handled correctly.

Read more about Screen Groups here.

Here, it is recommended to separate the screen groups cleanly. For example, a soft edge blending of three projectors also needs the content of the other areas due to the overlap, but it does not need content from the other screens that are still used in the project. Here, it is recommended to separate the screen groups cleanly or, as a quick and dirty solution, to set all layers to “Render only on home screen.”
 


Sync

If possible, it is best to use the sync board options. To do this, apply the sync to the relevant monitors in the Nvidia control panel.
Synchronize Outputs - Genlock and Framelock Setup 

To ensure that the sync is applied, you can use the on-screen overlay to see whether it is activated. The correct status would be “Swap Group,” which means that the sync of the Quadro sync card is applied.
On-Screen Statistic

Even if sync is not theoretically necessary because the displays are not arranged in a way that would make it noticeable, it is better to use it anyway from a performance perspective. Although this improvement often only results in a very slight performance gain, it often provides greater stability.
