Press play on the video. It'll jump straight to the section that answers the
title above — no need to watch the full video.
How to edit Python code and use command-line arguments to run LTX-2 on low-end hardware without crashing.
RAM vs VRAM Requirements
While you can run LTX-2 on low VRAM (3GB), the total combined amount of physical RAM + VRAM must exceed 36GB (the cumulative model size) to prevent system crashes.
The Purpose of Reserve VRAM
Using the '--reserve-vram' parameter is crucial for Windows users to prevent background applications or the Windows UI from competing for VRAM with ComfyUI, which typically causes 'Out of Memory' errors.
