Greetings,
I am playing MSFS SU10 in 2D on Windows 10, CPU i7 6700k (hyperthreading on), 16 Gb ram 2666 Ghz ddr4
GPU is GTX 1080 Ti, Nvidia Studio Driver 517.40
LG monitor g-sync compatible (v-sync off) @ 1920x1080
In sim settings are: render scaling 120, TAA, graphic settings all on Ultra except TLOD and OLOD @ 150
AI traffic 25%, live traffic off, all other traffic settings 50%
In Developer mode, the CPU and GPU are shown having almost the same timing for main thread and render thread, sign of good balance between the two (noted I have upped the render scale to load more the GPU and improving the antialiasing). I learned to pay attention at CPU and GPU balance by reading several threads in this forum.
I reckon VR and higher monitor / TV resolution are much more demanding on the GPU, requiring more powerful systems and different settings
In flight, even above dense photogrammetry cities, fps are averaging 45 and the g-sync paired with LG monitor LFC (low frame compensation) yelds very smooth motion (I tried v-sync on and fps lock at 30 fps but got results noticeably less smooth)
On airliners in busy airports, frame rate drops around 20-25 but the sim is very playable because the ‘stutter’ effect due to the low fps is regular and apparent only when turning the aircraft or panning around the view (I have the motion blur effect turned on as this helps to smooth the in-cockpit and external changes of view direction)
Yeah, I don have have the latest and fastest pc on earth, still with the settings I use the sim is very smooth with no stutters, showing gorgeous, believeble graphics
Hope this helps - Cheers
