yes yes, I know what you meant 
… I only want to mention, thats also in other flight-sims this kind of optimizations are “beta” ( or more exact in dcs a preview of a beta ). We all hope allways for optimizations, but that takes time. If I remember back to ages for C64, where at the end was more possible than the original hardware can do ( e.g. 256 colors instead 16 )… so long ago…
And whats much better in DCS community ? - the community know and accept what “BETA” mean. There is constructive feedback in case users use the “Beta” branch and all know that problem can happen. If we read some reports here, where users joined the Beta, it sounds often , at least feelt, ‘a bit different’. You can imagine what happen if we get such a beta-Beta feature within MSFS, the topics might explode if somewhat goes wrong 
I own a 13900K ( doing video stuff ) and with to high TLOD I can also run into CPU limits, but usually the 4080 limits the fps ( near 4K ). In DCS its similar currently, my 4080 runs most of the time in 100%. But like in MSFS, it depends on amount of objects, and so in DCS at kind of missions. What DCS do is , it use much more RAM ( may be because it not need run on different platforms and so there are not ‘man-made / synthetic’ limits for the PC version ).
And don’t forget… the CPU load these days needs to exact interpreted. The new CPU have P-cores and E-cores. Normaly we not want to use E-Cores in games, or just only for Tasks which not need highest performance ( so far I understood, the new DCS model also manage that P- E- core distribution ). What needs to avoided are threads which needs Single-Core-Performance ( which can not split or need to split into more tasks ). But thats just not an easy doing…
