The attempts to explain lag are to address the idea that Single-Plane collisions are an injustice created by choice by HiTech. That lag 'exists' is not the explanation or the answer, but rather what choices HiTech has made to include a collition model that is as fair as possible. Is the amount of "un-fairness" remaining in how HiTech models collisions worse than not having collisions at all?
Let's examine some alternatives...
It's true that if your FE desides you collided, it could send a hit packet to the opponents front end that damages his plane too. But I think most feel that more un-fair to the pilot that never saw a collision, and more confusing.
Current scenario:
I see a collison. My plane is broken. Hey wait...how come his plane isn't broken...that's not fair!
Alternate Scenario:
I don't see a collision. My Plane is Broken. What the Hell?!! I never hit anything!! That's Bull Blah blah blah blah.
Alternate Scenario 2:
Planes Fly through each other. Every HO is blamed on the fact that there are no collisions. The ACM is this game is completely different from real life because there's no collisions. This game is no real. Blah Blah blah
I vote for the current scenario.
there may be others that are better...perhaps you can post and discuss.
Scenario 3:
I am in a fight with someone else, p51 dives in for the kill, overshoots, I get collision message even though I never saw the guy coming and he did manage to avoid me. I understand that my FE did see the collision and it was me the person that didn't because I was bz dealing with another threat, but what was the benefit provided to game play from that?
Scenario 4:
I am in a bomber, guy makes an intentional pass in front of my nose. I explode, he flies away laughing. Benefit to the game play?
Unfortunately, I don't have a better solution other than to turn them off. Again, I base my opinion in 6 years of playing this game. From my experience, it does not prevent people from flying through you anyway. I am not saying that everyone does that. The people that don't do it are not doing it because of the way they choose to play the game (looking for a realistic experience, dog fights, furballing, winning the war, survivalists, playing for score, etc). Those guys would not do it anyway (collisions or not)
Really, all we accomplish with collisions on is that instead if flying through you, the guy has to fly in front of you.
