IL-2 Developer Diary update

IL-2 Project Manager Han has posted Developer Diary #131 to the IL-2 forums today with a summary of work that the team has been busy doing all summer.

Included in the massive list are a shorter list of changes coming in a future update (Update 2.004).

Changes we’re testing now (they are likely to be included in 2.004 update)
80. REVI-12 display reticle corrected (its angular size increased by 12%);
81. Lift force loss and drag increase of a remaining wing after fragmentation of a wing corrected;
82. First optimization task completed: AI controlled aircraft on the ground can be doubled;
83. ‘Jumpy landing gear’ issue fixed thanks to improved shock strut model;
84. Bumpiness of concrete runways and taxiways reduced;
85. He-111 won’t rotate after an emergency landing;
86. Powered temperature gauges won’t work when engine is off;
87. Engine heat model corrected for Ju-87;
88. Oxygen deprivation model corrected (its effects are felt at higher altitudes than before);
89. German breathing devices are engaged at higher altitudes (by German flight manuals);
90. Pe-2 fuel gauge is backlit now;
91. La-5 cylinder head temperature gauge is backlit as well;
92. Pe-2 trimmer neutral position indicators work now;
93. Bf 109 E-7 mass correctly decreases with ammo spending;
94. New technochat message added telling pilot that an engine is deselected.
Han’s list is pretty extensive so if you want to check out what they have been doing or have already implemented – read it on the forum!

AI Optimization

Another reveal from Han was the work being done by Andrey Solomykin, the author of the flight model system in IL-2, on AI flight optimization.

One of our main goals at this stage of development is a significant increase in an amount of AI controlled aircraft acting simultaneously without a noticeable decrease in modeling quality, keeping realistic aircraft characteristics. The idea is to keep the physics modeling accuracy of an AI controlled plane the same as player controlled plane has and optimize only those modules which impact is only noticeable when you pilot a plane yourself.

Even on the most powerful systems, IL-2 can get bogged down by large numbers of aircraft and the cause of it is not the aircraft models themselves but all of the AI that are attached to those aircraft.

Apparently the worst of that comes from aircraft taxiing on the ground and optimizations here has allowed the team to do some further work with the actual physics implementation.

Read the Dev Diary for the whole explanation. They left us a cool video showing the impact of the updates and anyone who has experienced a very bumpy and springy landing should take note of this impending improvement.

The pace of news for the series is ramping up and I’ll be doing my best to keep on top of it!
