The game is GpU bound. Nothing wrong with that, most games are these days. 75 degrees is not frying your GPU, you can infsct leave your GPU on 75 degrees for one week straight and it will be fine.

What gpu do you have? Because I have a pretty lower end gtx1650 GDDR6 and it doesn’t go over 59 degrees, with 65+ FPS at 1080P

there is absolutely no solution on our end (the players). optimization and polishing the game is something that will come last from the devs.
