I went from a 3060ti to a 4070 Super recently… def saw improvements and was able to increase quite a few of the settings. Things like complex scenery and aircraft are still taxing, as well it does not eliminate all of the other little issues when the software just doesn’t run efficiently. However, overall I’m pleased with the increases in performance but they are not massive by any means.
That said if I had it to do over, I would really consider the 4070ti Super and spend the extra money for the additional vram. These cards Nvidia is selling really should have more vram. I definitely found that the sim just eats it up and 16gb would improve things quite a bit.
