IL-2 Sturmovik: Battle of Stalingrad News

Dear friends,

We're glad to present you with another update of the sim - 5.204. It brings the new Collector Plane, the very late war Ta 152 H-1. This unique machine was a pinnacle of German piston engine technology of its time, designed to be able to engage Allied bomber formations at very high altitudes and prevail over Mustangs and Spitfires. You could say it was over-engineered with its three-stage (!) supercharger and two simultaneous boost systems (MW-50 water-methanol for altitudes up to 10 km and GM-1 nitrous oxide for 11+ km). Yes, this is not a typo - this piston-engine aircraft could not only climb above the modern airliners (its ceiling was 13 km), but also be able to dogfight there.

Like most late-war German war machines, there were too few of them to make a difference. By the spring of 1945, when it was too late to intercept Allied bomber formations - Allied ground forces were advancing into the Reich from both the east and the west - only about two dozen aircraft were combat-ready. The few planes were used in the usual fighter roles and, ironically, much closer to the ground than they were built for - covering the takeoffs and landings of the new jet-powered aircraft (see below). This is similar to the story of the Allied P-47 Thunderbolts, which were designed for high-altitude combat and had special systems for it, but ended up spending a good part of their flying time close to the ground because they proved to be the best ground attack fighters of the US Air Army Air Forces. The Ta 152 Pilot's Career mode is only available on the Rhineland map (I./JG 11 since March 1st, 1945), but for player convenience, it is also available in the Scenario Quick Mission (AQM) mode on the Normandy map, and of course on every map in the game in simple Quick Missions.

There is a new mission type available for the late war German Career Mode - Jet Airfield Cover, where you should prevent the Allied fighters from shooting down jet aircraft near the airfields where they were stationed. New jet aircraft such as the Me 262 and the Arado 234 were hunted by the Allies when they were most vulnerable - during takeoff, when their speed was still low, or during landing, when their speed was already low. One such episode is shown in our promo video.

The Jet Airfield Cover mission type is available not only to Ta 152, but also the Fw 190 D-9 and several Bf 109 squadrons that were flying it historically.

Another important change is the increase of the maximum amount of buttons and axes on a controller from 64 to 128 - modern joystick and throttle combinations could exceed the old limit when connected to one another. This shouldn't be a problem anymore.

Last but not least - please check out the new section on our website, Museum. We have been preparing it for some time, here you can find the historical information about the aircraft and ground vehicles modeled in our sim.

Dear Friends,

Today we'd like to start this dev blog in an unusual way - with a retrospective. Over the years of work on IL-2 Great Battles we have created many aircraft, and for each of them we could write a whole article about how we searched for information, solved contradictions in documentation and drawings, built a visual model and designed a physical model and FM. But sometimes you can just show it - as they say, sometimes a picture is worth a thousand words.



With studio-quality lighting, rather than a real-time renderer, you can really see how much work and love went into recreating each of our aircraft. The Hawker Hurricane Mk.II, a collector's aircraft we built three and a half years ago, is still a model of excellence in both visual modeling and physical model perfection.



As for the latest news, the new update 5.204 will be released soon, in two weeks; its testing is almost finished. It will include the new Ta 152 H-1 Collector Plane from the end of the war, which we described in detail in Dev Blog #358, as well as a number of important improvements and changes.

Modern controllers have many buttons and encoders, and their total number may exceed the limit of 64 buttons or axes if multiple devices are connected at the same time. Therefore, to support such configurations, the maximum number of buttons supported by the game will be increased to 128.

Several bugs in the career mode will also be fixed, such as friendly aircraft attacking the player group, and a new type of combat sortie will be added for the Luftwaffe on the Western Front - covering the takeoff and landing of the jet aircraft. Since Allied piston fighters usually could not catch up with them in the air, they used the tactic of shooting them down on takeoff when they had not yet gained much speed, or on landing when they had already dropped it. To protect the jet-powered Me 262s and Ar 234s from such attacks, they were covered near the airfield by German piston fighters, including Ta 152s.

Dear friends,

Today we would like to show you the first screenshots of the new map under development - Odessa. In addition to the city itself, it includes almost all of modern Moldova and small parts of Ukraine and Romania. At the moment, about half of the work is done. It's a big task because more than 400 settlements and at least 30 airfields are planned. Odessa, Tiraspol, Beltsy, Bolgrad, and Kilia are finished, while work is still going on with Chisinau, Kotovsk, Izmail, Voznesensk, Rybnitsa, Galati, and others.


Odessa in the 1940s is modeled with a good level of accuracy; it is correct to a point where one can learn its layout and landmarks: in the city there are the famous monument to the Duke, the cannon of the frigate "Tiger" monument, the opera house, the railway station, Kulikovo Field, Potemkin Stairs, "Chernomorets" stadium, the prison building, the artillery school, cathedrals, and monasteries, the old Vorontsov lighthouse (it was blown up during the war and rebuilt in the early 1950s) and others.

We would like to repeat our appeal to contact us if your ancestors fought in the war in aircraft and ground vehicles you can control in our sim - if you have the photos of your loved ones taken during the war in your family archives, we can add them to the virtual cockpits as default photos instead of the generic ones, with your permission.

The idea is to have a photo that the pilot or tanker would have placed there himself, so a photo of his girlfriend, wife, children, or parents is needed, not a picture of him. For example, this is what the family photo of Squadron Leader Jack Collins looks like in the cockpit of the Typhoon, as shared by his son (the Growling Sidewinder video tells more of his story).

Dear friends,

We have released a new update 5.203, which includes a new ground combat generator mode for Tank Crew owners, which we told you about in one of the previous editions of the Dev Blog, new mission types for the scenario generator and career mode, updated descriptions of all WWII aircraft, added popular campaigns created by enthusiasts AEthelraedUnraed and Juri_JS, and much more (the full list of changes is below).


One of the most important innovations in this version is the introduction of a new dynamic battlefield system in the pilot's career mode to create the most interesting and varied scenarios and to optimize the CPU load (usually, the graphics card's performance limits the saturation of the battleground to a lesser extent because the objects are far apart and they are not rendered with high detail all at once). Since this system directly affects your gaming experience, let's learn more about it.


[h2]DYNAMIC RESOURCE ALLOCATION SYSTEM[/h2]
The new system now works in WWII career mode escort scenarios, where the player's fighter escorts AI-controlled attack, bomber, or transport planes - there are several unique variations, from escorting Ju-52s flying out of the Stalingrad cauldron, or bombers on their way to V-1 launchers in Normandy, to escorting transports with paratroopers during Operation Varsity at the end of the war.

It is based on a dynamic resource accounting mechanism. Both individual combat vehicles and groups of them are assigned a certain performance cost - for example, a truck requires very few CPU resources, while a group of heavy aircraft requires many - and request permission to appear in the game world from the resource controller. The resource controller first checks the amount of resources required, and then, in the case of an aircraft group, the probability of its appearance. The only exceptions to this general rule are such key elements of the scenario as the player's unit, its cover or other groups covered by it, and a group of the player's air targets - they will appear in the mission anyway.

If a unit or group is destroyed, crash-landed, just landed, or otherwise removed from the game world, the controller will use the freed-up resources to create a new group. A bonus effect of introducing this mechanism is that it virtually eliminates the problem of many objects appearing at the same time for ground vehicles, which can cause a noticeable "stutter".

[h3]Early warning posts[/h3]
Enemy interceptors appear in the air for a reason - they are summoned by observation posts located along the front and rear lines. They are organized into three large interception zones along the front line - each zone is assigned its own group of interceptors. The posts request the appearance of interceptor groups from the Resource Controller and then direct them to the group of aircraft to be intercepted: interceptors can either appear in the air at a sufficient distance or take off from their home airfield. In the current implementation, Airborne Warning Posts do not initiate intercepts of single aircraft or groups of fighters that don't cover strike aircraft.

[h3]Additional Events[/h3]
When generating the next day in Pilot Career mode, additional events are selected that may occur on the player's route that day if a friendly aircraft is passing nearby. For example, there could be a pair of enemy fighters on a free hunt or a group of friendly fighters, an enemy reconnaissance plane at high altitude, a group of transport planes flying to the rear, an airfield cover flight of 4 fighters, and so on. They will not suddenly disappear into nowhere - if you follow them, they will fly their full route and land on their airfield, and to save resources, if they are far enough away from enemy planes or the player's plane, they will be removed.

[h3]Other changes[/h3]
Player squadron aircraft are limited to two flights of 4 aircraft each and the second flight if covers the first by default. Large-caliber anti-aircraft guns will stop firing when friendly aircraft are nearby and will not distinguish the player's aircraft from other available targets. Ground vehicle firing modes have been optimized (they pause between bursts of fire).

[h3]Effect of career settings on performance[/h3]

The "Air Forces and AAA" setting has the greatest impact on performance because aircraft consume the most CPU time - it limits the appearance of air groups (other than the player's link) and anti-aircraft artillery units on both sides in the scenario. The higher this setting is, the more aircraft there will be in air groups, the more anti-aircraft artillery units will be operating simultaneously, and the higher the chance of a random event being triggered (and the higher the CPU load).

The "Ground Forces" setting controls the number of ground vehicles to which resources are allocated, independent of the "Air Forces" and "AAA" settings. For example, you can set "Air Forces and AAA" to the minimum and "Ground Forces" to the maximum. By combining these settings, you can find a setting that will allow you to play comfortably in Pilot Career mode on your computer.

As for the "Power Balance" setting, as you can see from its variants "enemy inferiority - parity - enemy superiority", it makes the enemy forces weaker or stronger than the forces of the player's allies, both quantitatively and qualitatively (experience level of pilots, marksmanship, etc.). For example, at the first setting, the chance of a group of enemy interceptors arriving is so low that they may not appear at all, at the equal setting this chance is about 50%, and at the enemy superiority setting they will almost certainly appear.

The new battleground system will be extended to other types of career missions if it receives positive feedback from the community.
