This is the only LTX 2.3 video workflow so far I that I can run on my NVIDIA GeForce RTX 3050 4GB vram GPU and 8GB ram laptop.It's not fast on 4GB and probably much faster on 6GB and 8GB machines.I recommend having these settings in your run_nvidia_gpu.bat file:--windows-standalone-build --lowvram --force-fp16 --use-split-cross-attentionSo change the first line to something like this:.\python_embeded\python.exe -s ComfyUI\<a target="_blank" rel="ugc" href="http://main.py">main.py</a> --windows-standalone-build --lowvram --force-fp16 --use-split-cross-attentionHere are the filenames and where to Place them.
