Why still no dive acceleration difference?

So far you didn't provided any evidence that would suggest that there is something fundamentally wrong with the game. IIRC Your picture that shows dives is from the post war magazine article.

And you will be hard pressed to find any RL test with planes diving at 90 deg straight into the ground or any 90 deg diving test for that matter, ~45 deg maximum angle during the dive is more typical.

would you please show me the link or so, I am new here

I am not here to attack someone

acctually I will be happy if I am proved wrong coz I will not have to be
plaged by this issue anymore and can fully enjoy the Il2

However, thru my/our calculation, things are different with those shown
in Il2

acutually, I do not believe the 45 degree dive is similar to 90 degree seriously

and this is the the blank point we are trying to figure out.

Fw 190 defence action will always start with a split s followed by a certain period of almost 90 degree dive

so the veticle dive has it's meaning

letme show you some clue here

with the speed increased, the back-drag force will increase pronouncely
due to 1, deformation , 2, propeller pitch, 3, propeller tip speed,4, air wave darging force.

with this backward force increased largely.

the heavier aircraft should prevail in the diving.

roughly it is the result I got, and I am quite comfident it is meaningful
and to some extence correct.

air wave darging force

No. But you are trying to communicate in English - and failing.

sounds u r happy to find this

instead of finding some truth

mayshine, I've recommended you to do this test:

Take a Fw 190A-9 and a Spitfire IX 25lb, start at 550 km/h at 1.5km altitude and dive them to a place 15 km away. Check their speeds.

Have you done it?

I can also assure you that the issue has been brought up again and again over the years and that il-2 is fairly accurate at typical combat speeds. The limitations will be reached only when you reach very high speeds, where the effects of near sonic flight are not as strong as they are in real life.

I fairly know this, I start Il2 by 2004,

of cause spit will lag behind when it is closing to it's limit and start shaking

but

what I want to propose is fast and verticle dive

a intensive speed increasing dive, u sure they will perform in the same way?

obviously 15Km is not a steep dive
