Some realistic expectation is the key to success. This sim was not released by the developers with any intention for users to run at 4K and every single setting cranked up to Ultra. In fact no sim I have bought has ever been behind the hardware curve in terms of performance, its always the other way around and hardware has catching up to do to enable the sim to run smoothly at max settings.
When I tune a sim I switch on a frame rate counter (developer mode in FS), start low and work up until the frame rate is around 35FPS in London or New York and then I have got about as much performance out of the sim that my hardware is currently capable of delivering. That is what the OP should be doing in my opinion.
Indeed, but it is far easier on the gpu to push out 2k pixels than 4k pixels at 60fps, thats not rocket science
But I will test later at 2560x1440, 3440x1440 and 5120x1440 and see what differences, my 49" is just below 4k but not much so will be interesting to see what difference Res makes on the fps in this sim
I stand corrected, just tested at 5120x1440, 3440x1440 and 2560x1440 and on my sys the difference between the top and bottom Res was only +30% fps, the bottom Res only had 22% less gpu utilisation, I guess this sim needs DX12 and DLSS and just better utilisation for cpu and gpu alike
