Yes, removing mods should be the first thing to do. Remove all of them and check if it works. If it does, add one after another.

Depending on the map, it might be useless as the light might be baked into the ground texture itself. Other than that, it's already been wished for quite a few times.

The altitude on the map shows the density altitude (with the influence of temperature). The altimeter in cockpit shows pressure altitude. So unless you fly at ISA temperature, you will always see a discrepancy between the map altitude and the altimeters in the cockpit. As the default temperature of DCS is +20, ISA +5 degrees centigrade, what you describe is the correct behaviour.

No, there is not as of now. But you can look around it... Just move the head forward/aft/up/down as necessary (No TrackIR needed).

You can fly it perfectly fine without AI, but if you are not convinced, just trial it for the 2 weeks and decide after that.

Ich hab bis vor etwa einem Monat mit DLSS gespielt, aber ein DLSS Indicator ist mir nie aufgefallen...

In DCS selber gibt es meines Wissens nach keinen DLSS Indicator, also muss das von einem anderen Programm kommen. Meine kurze Google-Suche scheint auf das Windows Registry zu deuten. Am besten kurz selber Googeln, ist am einfachsten.

Fly the mission in single player, showcase the problem and then quit the flight. In the debriefing window, you have a button at the bottom "save track" or similar. Save it somewhere where you can easily find it and upload that .trk file here.

Full fidelity modules can have several buttons for Radio/intercom. The default # key is usually for the intercom, which doesn't transmit anything by radio but uses the intercom system, to which only ground crew can listen to. There is usually a dedicated radio button that you need to use to be able to actually transmit over the radio. Additionally, make sure the radio preset frequency matches the receiver which you want to contact.

Well, the solution to your problem either way is to fly at the minimum speed (100kph) required to launch multiple rockets.

Because ED hasn't modelled it for the Mi-8. The Mi-24 being much newer received this effect, just like the new Ka-50 update. One small rocket doesn't sound right though, you got a short track of it?

That's been the default behaviour since forever.

There is no light there, the space is occupied by antennas.

You set the QNH given by the briefing on ground so your altimeter reads the elevation above mean sea level. Above the transition altitude you set QNE/Standard to get flight level. There is no real altitude, only altitude in relation to your selected reference altitude. That's either flight level, level above ground (height), altitude above MSL, density altitude or other. Temperature affects your altimeter so it reads something different than height, that's normal. You don't compensate for that normally. That's one of the main reason for the devaition you see.

Yes, you set it there. Should be in the ingame briefing. Depends on the airport, but around 5000ft is a decent altitude to switch the altimeter.

You don't have to but it helps to prevent overheating or also helps so you don't forget to turn it off when you are cruising/RTB. Set avionic language in the gameplay or misc settings to english.

Altitude in the external view should be true altitude while the one in the cockpit is pressure one. Difference between these two is temperature effect. What's the temperature in the mission? Also, don't set QFE, almost nobody flies QFE anymore. You either set QNH or QNE/standard above the transition altitude.

The map should have nothing to do with it. Check for AI wingmen in your flight.

3) That purple haze is the exhaust flame effect that didn't got rescaled with the model and is now way too big. Tagging @NineLine @Flappie just to make sure it's seen. Also probably would have been better if you posted it in the WWII Assets pack subforum, but at least you posted it...

Check your loadout (ammo count) and switch settings.

Have you made sure the historical filter is turned off? It's the clock/watch icon at the bottom in the ME.

When you select the bomb to load onto your aircraft, click on the orange triangle to see what fuzes are available.

Not that I know of. It's either the avionic language or the unit setting in the gameplay settings, I don't remember. According to the manual, the unit setting should only affect the outside measurements, but maybe worth a shot to try too.. Some may also have specific metric or imperial cockpit liveries in the special settings. For some you can download such a livery.

It's not implemented in all aircraft.

You should supply a short track so we can see more.
