Best I can tell, MSFS 2020 had that inherent flaw built into it from the get go. It tried to do the whole Main Theread or as much as possible on one core. The rest of the stuff was divvied out to the other cores as needed. This throttled low to mid spec PCs and greatly limited Xbox.
This made the already CPU intensive sim extra CPU intensive because one core was always being throttled by its clock speed. So the speed of the cores mattered most, even though only one core needed to be fast.
My understanding is they would have needed to basically rebuild their engine to fix this.
Now, keep in mind Asobo is mainly a game engine company. Sure they make games too, but they have all been made, often for different companies or producers, with the same Asobo engine and it has evolved and grown through the decades with each new game. Without their engine, folks wouldnât hire them to develop their games. That Asobo engine also gives us in house graphical feasts like A Plagueâs Tale 2. So, to Asobo, reworking the game engine is no big deal. It is what they do. But it takes a HUGE portion of their team to do it, and then they have to re build the sim on top of it. This is how they make THEIR money.
They know what was holding the MSFS 2020 engine up and I expect they set out to fix it. Once fixed, the sim should be able to do so many more things at once, they could add a whole bunch of new features and graphical wonders and still run on a Series S.
At that point it just makes sense to call it a sequel. Bills need to be paid after that much work. Theyâve rebuilt the entire game to run and look differently on a new updated engine they also made. Sure some parts of MSFS will remain basically the same. Like Forza titles. This is an incremental sequel not an entire ground up reworking and rebuilding. But the whole thing had to be built around an updated graphics and game engine, so it is a new game.
Asobo better understands the hardware limitations of the Xbox. This will now be their third Xbox Seies generation title.
I know, I keep talking Xbox but it is a low-mid PC at best, and if the sim better scales to that hardware it will also scale up far better than 2020 ever did. An Xbox or a mid tier PC will benefit FAR more from core optimization than a top tier PC. It will potentially allow for a lot more to be calculated at once than 2020 did.
2020 was always flawed to the literal core.
Asobo seems to think they have fixed that flaw with this sequel. The Xbox isnât getting any faster so it would seem to be a top priority to better optimize their engine for systems of that spec. Not just for MSFS but for other games they develop or are developing.
They know what they had to fix to get more out of a flight sim this generation. Theyâre getting a second chance. Last time they had no experience making flight sims.
So yeah, I think they will have to improve the whole multi threading issue. That seems to be the only way they could add more features to a seriously limited system like the Series S.
