Making character Lora for wan 2.1 on RTX 5090 - almost 24 hours straigth, still only 1400+ steps out of 4000

Hi guys, quick question. I’m not sure why, but I’ve been trying to train a LoRA for WAN 2.1 locally using AI Toolkit, and it’s taking a really long time. It already crashed twice because my GPU ran out of VRAM (even though the low VRAM option is enabled). Now it says it needs 10 hours lol. I’m not even sure it’ll finish if it crashes again. Maybe you can help me out - I need to create a few character LoRAs from real people’s photos for my project. I also want to try WAN 2.2 and LTX 2.3. Any tips on this would be really appreciated.
