75mm HE & HEAT disappear at 3000m, Panzershrek round disappear at 1000m

[parallama]

The other day on the testing server I was doing some testing and documenting of using the Panzer 4D, STUG 3B and Panzershrek for artillery using one account to shoot the rounds and another account to stand below the locations they fell. For ease I will call them the 'Fire account' and the 'Spotter account'

Panzer 4D & STUG 3B:

For the Panzer 4D and STUG 3B when HE & HEAT rounds were aimed to fall below 3km there was a visible explosion and sound on my spotter account (I documented the settings to fire them accurately up to 2920m). However all rounds that were aimed to go a bit further over 3KM had no visible explosion or sound on my spotter account. I have had my spotter account play both as axis infantry and as a axis tank (in case the settings were different for infantry) and still no visible sound or explosion. Throughout this I only used HE and HEAT rounds.

My impression was that all rounds above 20mm (barring AA guns fuses) would have their trajectories calculated up to 6km. Is this just my PC/internet performance (both of which are not good) , the 75mm on the 4D & STUG 3B being coded to disappear after 3km or a bug?

Panzershrek:

I did the same setup as above by having a fire and spotter account (spotter stayed infantry throughout). Again I was able to document using it out to 950m. However a tipping point was at the 1000m range.

I found that rounds which would of otherwise gone over 1000m did not make a visible or audible explosion on my spotter account however did make a visible and audible explosion on my fire account (aka the one firing the Panzershrek). Are Panzershrek rounds coded to have no effect on other players after 1km/after a certain flight time (which coincided with 1km)

I acknowledge long range artillery play with low velocity, mid calibre guns is pretty niche so it is understandable if these were coded to disappear after 3km and 1km respectively.

it's normal, almost every projectile disappears at 3km for performance reasons.

some are server tracked, like the mortar rounds.

very annoying for navy and some air units.
