IL-2 Great Battles Updates 2021

You are making me feel afraid to go for a fun Il2 quick mission before going to bed, @Troll
Cuz I hate going to sleep frustrated :neutral_face: :smiley:

Yeah, I had that on random.

I think it’s mostly me being out of training… :wink:

But what’s the verdict on the reduced pilot fatigue model…?

Update 4.701

Hello Everyone!

Today is a Big Day for our project and our community - update 4.701 is now available! And with it comes a new game world technology – cloud rendering based on hypertextures. This technology, in comparison with the previous one, carries a number of improvements, such as:

  • Increased variety of cloud cover;
  • A new level of scale of cloud formations;
  • Higher level (macro level) of cloud structures;
  • Greater realism of structures and forms of cloud formations;
  • Improved lighting model of clouds, and objects under and in the clouds;
  • Diverse structure of overcast clouds (including “windows” and cloudless areas);
  • Localization of precipitation under significant cloud formations and, as a consequence, localization of precipitation on the map;
  • New visualization of precipitation at a distance;
  • New rainfall lighting model;
  • Lack of repeatability of the cloud distribution map on the scale of the game map;
  • Reduced number of “compromise” solutions such as “object outlines” “mountain intersection aliasing”, etc.;
  • Increased performance of the graphics subsystem.





The mission format was changed, so third-party missions and campaigns need to be re-saved using Mission Editor or Mission Re-saver utility. Old track records can be played by deleting the .msnbin file from their folder. We have taken great care in mimicking the current cloud selection options for mission builders, so all your older missions are technically compatible with the new clouds. However, the clouds will look quite different and you may need to adjust your mission design to get the desired result. The new clouds are much larger on average than the current ones so visuals will be quite a bit different. We apologize if the new clouds inconveniences mission makers. We hope that the improvements outweigh any problems and we also hope to add some additional cloud patterns in the coming months.

Overall, we hope the new clouds will significantly increase the visual realism of our simulator, as well as bring a new greater simming and gaming experience.

Another great addition in this update is for Flying Circus – Vol. II. Included is the versatile two-seater - the German DFW C.V. It was the most common aircraft of this type on the German side from 1917 until the end of the First World War. This small aircraft is capable of carrying up to 200 kilograms of 12- and 50-kilogram bombs. Additionally, it is armed with a Spandau machine gun and a defensive Parabellum. Various modifications are provided for the installation of a camera, radio, defensive turret with a Parabellum coaxial machine gun or a Becker 20mm automatic cannon. The placement of the Benz Bz.IV engine is a peculiar one, in which the pilot has significant difficulties in looking ahead. However, this motor is quite powerful at 200hp. Quite an accomplishment in 1917.




In addition, this update brings a long-awaited development goal - all planes are converted to 4K skins texturing. This was done in coordination with a few super dedicated community members! The last aircraft to be converted from 2K to 4K texturing in update 4.701 is the Yak-1b series 127. In addition, the Battle of Normandy development plan is moving along, and in this update, all map building objects planned for Normandy are available in the Mission Editor. Also in 4.701, all ground vehicles, which were planned for the Flying Circus – Vol. II were added to the project. Finally, there are many other changes and improvements, a complete list of which you can find below:

Aircraft changes
36. P-51D-15 engine model was fine-tuned and its speeds increased slightly (by about 5-8 miles per hour with a boost of 67 inches) as the result;
37. P-51D-15 handling at high speeds was improved. Controls are a little less stiff within the envelope;
38. P-51D-15 behavior at high Mach numbers was tweaked, Shaking and loss of control at the edge of envelope more severe; More likely to suffer airframe damage if trim used too liberally at high Mach.
39. P-51D-15 autopilot has been improved - the level flight assist more accurately maintains the altitude with different amounts of fuel remaining;
40. The excessive water spattering on the P-51D-15 canopy during the rain has been reduced;
41. Fixed shaking of both SPAD VII.C1 150 hp and 180 hp in the absence of a control signal at high (but lower than buffeting) speeds;
42. The issue of the absence of US pilots in B-25 and A-20 aircraft during Winter has been fixed;
43. The texture of the smoke generators in the hangar was corrected;
44. Fixed the “lagging” of the ammo explosion effect from the aircraft;
45. Reduced the likelihood of cases when a high-speed frontal collision won’t cause aircraft destruction;
46. Ju 87 D-3 brake flaps won’t visually disappear at a distance;
47. The AI pilots try to not hit allies in the line of fire (functionality restored);
48. Fuel tanks and aircraft structure are correctly damaged by AP projectiles fired by simple (non-detailed) AI-controlled objects;
49. Fokker D.VIII: the anemometer is correctly visible from the cockpit;

Ground vehicle changes
50. KV-1s and T-34 mod. 43: the interior visual model of the gun in the mantle area has been improved;
51. KV-1s machine gun ammunition corrected (coaxial MG 25 magazines, rear MG 9 magazines, bow MG 15 magazines);
52. The overestimated combat survivability of guns, guidance mechanisms, electrical systems and radio stations has been reduced on all tanks, both detailed and simple. Tank guns can be disabled by an AP round hit of a similar caliber or multiple hits of .50 and larger caliber AP bullets;
53. MG firing sound correctly stops when a detailed tank is destroyed;
54. AI-controlled tank and aircraft turret MGs sounds corrected;
55. Some AI-controlled tanks and AFVs will fire their coaxial MGs (Humber, SdKfz-222);
56. A game and dedicated server crash bug that could happen randomly in multiplayer missions with A LOT of ground vehicles has been found and fixed;

Career and Quick Mission changes
57. In Сareer mode the UK and US crews have the correct crew visual models and paint schemes depending on their country;
58. Random encounters with high-altitude interceptors (including Me 262) added to AQMG;
59. In AQMG, the behavior of AI bombers in Intercept Bombers type missions has been changed (they may panic, drop the bombs and run away when the flight leader is shot down);
60. UK and US callsigns of ground observation posts have been corrected in AQMG;
61. Correct paint schemes are assigned to aircraft covering the airfield in Attack Airfield type missions in AQMG;
62. The cruise speed of P-47D-22 and P-47D-28 in Career mode missions is adjusted to the historical 250 mph;
63. Two previously AI-only squadrons in the Career mode on the Rhineland map can be joined by the player: No. 322 (Dutch) Squadron RAF and No. 329 (Free French) Squadron RAF.
64. The redeployment mission from Migalovo to Dugino on 22.10.1941 for the German II./LG 2 squadron (Bf 109 E-7) has been restored;

Mission Editor changes
65. Location of the toolbars are saved correctly, system toolbars and sections are removed;
66. It is now possible to set a block of buildings state to ‘destroyed’ by not entering all the individual IDs of the blocks, but only one ID = -1 with a damage level of 1. This should greatly save time for adding a destroyed block of buildings, reduce the size of missions created, mission loading time, and slightly increase performance.
67. Setting the value of block damage with ID = -1 between 0.1 and 0.9 will result in random destruction of the corresponding percentage of buildings in the block (the fewer buildings are in the block the more random it becomes). The random destruction of specific buildings is tied to the coordinates of the block on the map.


Lots to like with this update. :sunglasses:



That reads as a fantastic update! Will try some flying in it tonight.

109 AI is bugged a little, it tended to push the stick, pushing negative G far too long and hard to be realistic. Level was set to random.

Clouds are amazing.



Dear Pilots!

Happy Holidays to everyone in the IL-2 Sturmovik community! May it be filled with good health, family, friends and lots of time to play your favorite virtual air combat simulation!

Today’s Developer Diary is a showcase of the beautiful P-51B which we are working very hard to finish for you by the end of the month. Just some minor bugs are left along with still finishing the tricky Malcolm Hood.

So after Normandy, is the next title going to be Battle of Development?


Battle of Guadalcanal I hope :wink:

Update 4.702


I don’t fly much anymore. And my old squad has disbanded and moved on. But we still chat and joke about current events and old times. A favorite quote from the IL2 forum that we use for nearly any subject that holds potential for disagreement is, “Were you there!?” It just might replace “Two Weeks” in sim quote folklore.


@B12, have a look in this thread and maybe continue the debate there?

My dudes, check this answer I got over a bug report I filed in the official zoo:

Anybody else notice the AI pushing negative G in a rather unrealistic fashion? I had it set to “Random” skill in the QMB, and the 109 kept showing his belly, trying to push away. I rolled and followed easily, so it didn’t exactly work for him, but it looked hella silly tbh.

Yes, we know about this “feature” of artificial intelligence, everything will be fixed in a complete revision of artificial intelligence.


I noticed this myself a couple of weeks back and also felt it a silly move on the AI’s part. Glad they are aware and working it.

@B12’s thread immediately above was “hidden”. This might mean he wants it deleted and so I don’t wish to quote him against his wishes. But I agree almost completely. Having said that, I like Jason. @B12 probably does too. What Jason did to turn RoF around was alone worth a Lifetime Sim Achievement Award (what? you’ve never heard of the “Elsa’s”?). The purchase of IL2 was a risky leap and he and the Russians pulled it off. Douchy people abound on that forum. But intermixed with the haters are the lovers. And Jason is either incapable of telling them apart or he sees them as two sides of the exact same coin. Here’s what I have learned in my far-too-long “career” in this hobby starting with FalconAT and MiG-29: The dedicated sim types want to feel like they are part of the team. The often make the mistake in believing that they are more “invested” than they really are. They also often make a similar mistake of thinking they are more informed than they really are. But those two traits come with the typical passionate combat sim customer. And for every one who takes it way too far and only succeeds in being a domineering asshat, there are five who really do have something meaningful to add to the experience for everyone else.

Responding below. I agree that the words we choose is important and that no individual who hasn’t harmed a child or dumped toxic waste into a river deserves a personal attack, whether a member of this forum or not. I might suggest that this is the perfect time to put “…Updates 2021” to bed and start with a fresh year.


I’ll be the bad guy, of course. We think @b12’s post can be reworded and we’re giving him the chance to do that. It reads, even if not intended to be so, as a direct and personal attack on Jason’s character (a member here btw). It’s fine to say pretty much anything about a company or even a role, and it’s not hard to de-personify it to make the same points. There is a difference, however daft/petty it might sound.


Would love to, but I have no IL-2 news. Someone find something and I’ll do the deed.
