How can I install Xformers in Comfy UI? I am using the standalone package. I've tried to install it via pip install but it still doesn't use it. Help would be appreciated. |

I made a simple benchmark test for the two gpus on my computers. Hope this can help anyone who is interested.
7900XTX is about 57% of RTX4090 at low resolution and batchsize (512x512x1),
yet only achieves 33% at higher resolution and batchsize (768x768x4).
would get even lower to 29% if RTX4090 uses xformers (tested but not listed below).
And so I wonder what would be the cause? Would anyone have any ideas?
Here are some details.
