I have a 3060ti TUF, and I can say that it's a generally quiet card. It uses the same cooler from the 3070 and 3080 TUF models. It also has a switch for Quiet Mode and Performance Mode, so you can adjust cooling behavior that way, if needed.
If you have it on the desk with you in performance mode, you can hear it when it's spinning up, but with normal headphone cans, I haven't found it to be particularly noticeable (unless your headphones are open-back). Quiet was a necessity for me, and this card has been great in that regard.
Also, it plays Metro Exodus on max settings (@ 1080p, 240Hz) just fine. I don't have a 1440p setup myself, but when it first came out, it was considered to be the lowest entry point for 1440p, though I think people generally agree that going up to a 3070 or above is still preferable.
Anyway, that's my two cents.
I doubt it. Portmaster has a relatively small share of users, and I bet it would be a waste of their resources to try to pin down a bug that is outside the scope of their client's normal functionality.
Best option is to try to fix it yourself and submit a pull request or hope somebody else does it.
