RTX 3090 is very slow on convs net compared to 1080ti

Hi guys, I know you are aware of it. I am wondering when this is going to be fixed and what caused it? It looks crazy to me that my 6 year old 1080ti with 3 times less CUDA cora is almost 8 times faster with 3x3 conv nets than my new 3090. I feel a little scammed :)
