I tend to see the cup half full, not empty.. Probably MSFS in the near future will be the leading platform.
I see it for what it is (from experience with it), I don't really subscribe to 1/2 full 1/2 empty debates. If Asobo can work some performance miracles "soon" it will stand a much better chance, but we're still doing the same process of "reduce graphic settings to hit 30 FPS" then I don't think that will bring in a much bigger audience, certainly not hold up to the gamer crowd and XBOX primary users.
With that said, 30 FPS works for me (and others) and is usually my target and I've gone to no ends of detail helping folks hit that 30 FPS target over the decades. But I don't ignore the feedback I get from those same folks wanting 60 FPS. I do get why so many use 60 FPS as the standard, many monitors default to 60hz, eye/brain works well at 60 FPS, many 3D shooters will do well over 60 FPS, and to be honest, if I could do 60 FPS and retain the visual detail I would too as 60 FPS is better than 30 FPS.
I don't know about how "evolving" will cure the performance issues, adding more complexity and features usually has a negative impact to performance. Maybe if they move to DX12 and do some optimizations, but the GPU is already the bottleneck with the Render Scaling above 100. Capping out a Titan RTX at 100% utilization takes some work
I consider the August 18th product to still be a Beta product or "early access" product.
I get why DLC providers are trying to promote MSFS, sales for P3D/FSX/XP have most likely come to a trickle ... not much option as the PR campaign was very successful.
