From what I’ve read, this problem should be solved in 1.7.1, because it incorporates the newer cudnn versions, right?


cudnn8.0.5 ships with the updated heuristics for the 3090 and cudnn8.1.x will cover the complete 30xx series. You could try out the nightly PyTorch build, which already uses cudnn8.0.5 and check, if the performance is improved.
