Neither. The NVidia 3060s are being heavily discounted at my local supplier, but STILL more expensive for worse performance than the Intel Arc 770LE. You should be able to do 4k with the Arc.
And FPS isn’t the be-all and end-all people make it out to be. Not in a flight sim. There’s a lot of fake 120fps and 240 fps panels out there using tricks like black frame insertion and interpolation to get a claimed equivalent to 240 fps out of 60 fps panels.
People still haven’t gotten in through their heads that if a pixel is the same value between “refreshes”, it simply doesn’t need to change values - there’s no need to “refresh” it, unlike the previous century’s CRT tubes. So only areas that change values need to be updated. Mostly moving edges or values when lighting changes (which doesn’t happen all over the screen even 30 times a second in many scenarios).
And of course, the higher you fly, the less rapidly the scenery changes, which is why FPS rates go up the higher you fly. Also, clouds don’t need as much GPU horsepower as the ground does, so clouds are relatively static compared to ground cover.
And if you’re using the interior view, the cabin mask that covers some of the outside scenery doesn’t need as much updating either.
So get yourself an Arc 770 LE. 16 gb of VRam, a 256 b it data bus, clock speed is within 7% of an NVidia 4090, and it can be overclocked 25% (not that you’ll need to).
It’s become a hot item, so there are some supply bottlenecks, but for the price !!! I can wait another month for a second one (but I am counting the days, for sure).
