Tat, your feelings do not have any bearing on reality.
The projectiles in Ashes are physical objects that simulate everything from mass, drag, gravity, etc.
In addition, units have to have a firing solution before they can fire which means that they will try to avoid shooting if they think they'll hit the side of a hill or shoot the ground (though sometimes they miss).
The fact that you think visual clipping is related to physics/simulation indicates you really don't understand the topic.
Is me not having knowledge of the inner workings a disqualifying factor for the capacity to formulate an opinion on the fun of a game?
and I never said visual clipping determines the physics/simulation.
I said an effort should be put towards matching them as best as humanly possible. That's a reasonable demand is it not?
why can't we concentrate on deciding whether or not the design choice of no hitbox for self and allies is a good one or not instead?
There is constructive criticism and then there is just plain criticism. In SUpCom, units would fire endlessly into the ground. They didn't have firing solutions. Our units do have firing solutions, they do the hit detection before they fire. While I have no doubt the clipping can occur (because we are dealing with polygons) it's a relatively minor cosmetic issue.
At the same time, what disqualifies your view is that you bald faced said that we don't have physical projectiles or simulation. To play the game and say that just shows a bias that is frustrating to deal with.
Let me put it succinctly: I am intimately familiar with Forged Alliance. I've seen the source. I've spent a lot of time in it. I was a big enough fan to publish Demigod which was essentially a mod of Forged Alliance. What they did with Forge was impressive but in terms of projectile physics, it isn't in the same class as Ashes. Not because the AShes teams are better developers but because there's so much more computing power involved to model it.
When the LOD display system decides to show/hide different elements has nothing to do with the projectile system.
BTW, thanks to the OP, the Hyperion LOD bug was found! Kudos!
