Image to video template workflow processing very slowly and crashing. Advice needed for optimization.
User reports LTX 2.3 ComfyUI image-to-video OOM and severe generation latency on RTX 3090, requesting optimization guidance and baseline settings.
This is a workflow-friction signal: even on high-VRAM consumer hardware, users are still hitting memory and throughput limits in LTX 2.3 i2v templates, suggesting continued need for clearer baseline profiles and lightweight graph variants.
