Simulation or Shoot-em-up?

[DogTailRed2]

I've been a fan of IL2 and waiting for this game for sooo long.
Being playing for about a month and I can't decide if COD is a genuine sim or a glorified Shoot-em-up.
To be a simulation you need to accurately depict the scenario, environment you are trying to model. I can't fly successfully over land due to FPS issues so I air-start over the channel. I'm in an aircraft that doesn't sound or fly like a front line fighter. I'm presented with radio chatter which sounds like a bad rap recording while I watch my AI steam into a bomber formation (with hyper-drive) and expend all their ammo in a single pass. I love the way 1-11's do snap wing overs when attacked. That's if they don't collide with their wingmen that is.
Then it's my turn to try and I find, due to control lag, I'm porpoising all over the sky and at the critical moment when I've actually got the hun in my sights I get the most almighty stutter and then he's gone.
So this is why, to me, COD is a Shoot-em-up because more and more I'm just setting up scenarios where I can fur-ball for a bit of fun rather than trying to immerse myself in an epic battle. In fact, sad though I say it, I'm flying COD less and less.
COD has no immersion or atmosphere. The Battle of Britain sim it aint.
