MS Flight Simulator 2020 update should fix CPU bottleneck and increase perf (mentions DX12)
Developer Asobo is improving the Microsoft Flight Simulator engine, ensuring that the PC version delivers higher fps. Furthermore, the game relies less on the processor but more on the GPU.
In a Twitch session, asobo CEO Sebastian Wloch said that three segments of the render engine have been re-written and architecture was improved. Wloch stresses that the tests have not yet been performed; therefore, Asobo cannot say what fps increase you can expect, but 10% seems feasible. The dev also mentions that the sim works with DirectX 12 ultimately. This allows the team to perform ray tracing. However, in the pending update, this will not be implemented. An update to DirectX 12 could also improve fps.
The team also discusses briefly the Xbox game version, which will also be published on July 27th. The game runs on both consoles at 30 fps and supports variable rate refresh. The Series X version will show 4k images, the Series S version will reach a maximum of full HD. On July 27, the update will be released.

Which is truly pathetic. No excuse for that in this day and age. It didnt even push 16 threads well for me on my 2700x.

Here's an excuse, what the heck do you want so much cpu usage for a game that's basically just visual? There's not much to process in this game except for the aerodynamics of the plane.

There is quite a lot more to process than just the aerodynamics. You are right in that the default airplanes are simplistic, with rudimentary systems. However, payware third party add-on aircraft are complex and often feature very detailed avionics and systems simulation. In the past, this has always taken a heavy toll on the CPU and significantly impacted performance.

Amdahl's law (which is a true math law while Moore's is not.. the second is marketing).. But first you also need the problem can be parallelized with an amortized sync cost (which is not the case of most computer science algorithms -_-') and know how much this sync will cost in total (in most cases it costs a lot).

Too bad the game don't use 32 cpu threads. 5950x is almost idle in this game
