I got a 4x generation speed drop after updating ComfyUI to version 0.11.0

Hello everyone. I ran into a generation speed degradation issue after updating ComfyUI from version 0.10.0 to 0.11.0. I have a very potato GPU, an RTX 2060 with 6 GB of VRAM, and I use Z-Image Turbo for image generation. On version 0.10.0 my usual generation speed was around 14 to 15 seconds per step. After updating to version 0.11.0, each step now takes 62 seconds. I tried switching to a different sampler, but it did not help and the speed stayed the same.

I assume that together with ComfyUI, PyTorch, xformers, and triton were also updated, which may have caused the performance drop on my hardware. Is there any safe way to downgrade back to version 0.10.0? I do not want to reinstall ComfyUI from scratch, because reinstalling all dependencies and nodes would be a real nightmare for me. Maybe there is a way to roll back PyTorch, xformers, or triton to previous versions?

Has anyone else encountered the same issue after updating? In any case, I would appreciate any advice from someone who understands this better than I do.
