with RTX 5090 200GB RAM - ltx 2.3 is broken; it runs out of memory (OOM) when I increase the frame count, but even when I drop it to 120 frames, it still OOMs—despite working perfectly before. I’ve tested it on multiple instances across VAST and RunPod

The traceback runs from latent_tiled_sampler.py (sample_tiled, line 923) through comfy/samplers.py into comfy/ldm/lightricks/av_model.py (_process_transformer_blocks). Start by reproducing with the attached workflow at 120 frames and comparing the reported allocations with the model load log. Done means either a reproduction that fits in the 32 GB card or a documented memory limit. The issue has no comments yet, so ask the maintainers which tiling setting they expect before changing anything.
