# LightAct Hardware video playback performance We thoroughly video playback performance of LightAct hardware, and the results are available on these pages. {% hint style="info" %} **Good to know**: if you are building your own hardware, please refer to [this page](/preparing-your-hardware-for-lightact/getting-your-hardware-ready-to-run-lightact.md). {% endhint %} ## Measurement methodology * All [servers ](https://lightact.com/hardware/)are measured in Base Configuration, meaning a single GPU. * 4 x 4UHD displays are connected to the GPU, one of them is used to render the GUI, the other 3 are joined together in a single 11,520 x 2,160 output with Nvidia Mosaic. LightAct is outputting to this output. * For playback at 30 and 60 fps, the output display refresh rate is set to 60 Hz, and for 25 and 50 fps playback, it is set to 50 Hz. * During the test, no other programs aside from LightAct are running. * Nvidia Control Panel is also closed. ### LightAct setup #### GUI * All windows are closed except for the Performance window. * The GUI opens and runs in Full screen. #### Project * Upon opening the project, we wait for all the thumbnails to load before starting with the test. * In the project, every 1 or 2 seconds, a new Play video node starts playing a new video. All Play video nodes are in the same layer and each Play video node is playing a unique copy of the same video file. In Performance window in Video playback section (available in 4.12) we monitored Missed frames counters. When they started to increase regularly, we knew the Max number of videos was exceeded. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
