This issue affects mainly those who prefer the simulated flight in a multiplayer environment, but it can affect even those who do not use multiplayer, better models are in their interests also
In multiplayer there are at least two important aspects:
- The performance in terms of FPS
- Consistency of the multiplayer environment
Unfortunately neither of the two aspects seems to be considered enough by most manufacturers which in most cases are oriented predominantly if not exclusively to the graphics, driven by legitimate commercial considerations.
Good performance cannot be at no cost, models made of more than 200000 polygons with bumps and specs are beautiful to see but cannot be suitable for the MP on the average hardware used by simmers since they have a significant FPS drop with more than 2-3 players.
We should also define the standard for "good performances", imho a "good performance" means to have and mantain a FPS of 30 without flickering, stuttering or FPS oscillation, what we call "stable and smooth 30 FPS".
This "stable and smooth 30 FPS" should be mantained into a MP session with at least 10 players.
Another neglected aspect is that of "coherence" of the environment, in other words means that all players should see and hear the same things. Consistency means that all players should have same meshes, same sceneries and same meteorological conditions.
As far as models is concerned all players should see other players airplane loadout and configuration as it really is, if i have uploaded a MK82 on a particular station is necessary that my partner sees it consistently, if i release the MK82 my partner should not see more it on that station.
Same applies to external tanks and all other animations not handled by default.
FSX limitations prevent to apply above standards to the maximum extent, however several thing can be done in order to improve the situation even if some limitations must be accepted.
Unfortunately above aspect are partially or not at all covered by most of models that are claimed to work flawlessly in multiplayer, instead I think it's time that users begin to demand it.
