We're very happy to introduce a slew of new improvements and additions to the game exactly a year after the last official update.

We are hoping that this patch finally makes this game worthy of the Il-2 Sturmovik name and that simulation fans will give our game another look and a new chance.

NOTE: This patch is incompatible with previous game versions when playing online.

The current version contains the following changes:

PERFORMANCE
* Performed a huge amount of work improving both average and minimum FPS in the game.
Most recommended-spec machine will see increased average FPS and a significant reduction in the micro-freezes that had previously plagued the game. Their frequency, duration, and overall FPS impact will be greatly reduced or completely removed.
* Completely rewritten rended pipeline, reducing CPU load;
* Rewritten texture manager, reducing stutter when loading new textures;
* Moved landscape geometry generator to its own CPU core, reducing stutters;
* Optimized tree code, reducing stutters when moving across landscape or rotating camera;
* Moved grass generator to its own CPU core, decreasing stutters during low-level flight;
* Moved all building and vehicle damage models to be pre-loaded, rather than dynamically loaded when they are destroyed. This increased mission loading times and memory usage, and reduced stutters when blowing things up;
* Improved multithreading in many other aspects of the code, improving minimal FPS on most multicore machines.

AIRCRAFT
* Added a Su-26 acrobatics plane.
You can toggle airshow smoke by injecting oil into the exhaust manifold. This is done with the WEP button by default. The default smoke is white. You can select other colors by selecting corresponding loadout options.
The plane also comes with four easter egg weapons that can be loaded onto the center pylon:
- Shotgun – fires explosive pellets with everyone’ sfavorite green tracers;
- Laser – fires a beam that sets an enemy plane alight. Effective distance is 700m;
- Antimatter mortar – fires anti-matter spitwads;
- Railgun – fires a shell that generates electromagnetic pulse that in turn destroys enemy subsystems, especially engines.
* Added Hurricane MkI and Spitfire MkI with constant-speed propellers and 100-octane fuel.
* Conducted a huge amount of work correcting and improving aircraft flight models as well as most engine models. All work was based on historical flight test data or flight manuals.
* Corrected negative G cut-out for carburetor engines. The effect will be noticeable at around +0.1G.
* Corrected the mixture control level on Hurricanes and Spitfires. It is now push forward for Lean, pull back for Rich. With that, moving the throttle lever to idle will return the lever to Rich.
* Corrected (increased) low-altitude speeds for most Brutish fighters (Spitfire MkI with DH and Rotol aircrews, Hurricane MkI with DH and Rotol aircrews).
* Corrected fuel flow calculations for most aircraft.
* Corrected (increased) radiator drag when it is opened.
* Corrected throttle control. The entire range is now useful.
* Corrected overspeed sound. It will now steadily increase in volume depending on airspeed.
* Made corrections to rough running on non warmed Merlin engines. Engines still require to be warmed up and won’t work properly when too cold.
Please note that engines still start with oil and water at colder temperatures. With Hurricanes, please keep throttle back until the temperature is at least 45 degrees C;
* Fixed issue that occasionally caused planes with landing gear raised to still show it in the down position;
* Corrected rough running on Merlin engines above 11,000 ft;
* Corrected control surface angles on the Hurricanes according to historical documents;
* Added drag to canopies opened in-flight on all aircraft;
* Greatly increased the effects of punctured radiators on engine temperature to make the effect more noticeable;
* Corrected boost operations on British engines;
* Fixed the inaudible hit sounds online bug;
* Fixed the issue that occasionally caused never-ending Stuka horns online;
* Corrected issue with the display of vapor trails;
* Corrected default trim tab positions on most axis aircraft;
* Disabled WEP for British fighters using 87-oct fuel;
* Bf.109
- Corrected rudder behavior.
- Corrected auto prop pitch operations. Max RPM target should now be the proper 2400 RPM;
- Corrected radiator drag;
* G.50
- Corrected temperature models for the engine. Also added +100 boost for WEP mode.
- Corrected (increased) horizontal speeds.
- Fixed engine heat balance that had previously prevented listed HP from being available at all altitudes.
- Added +100 boost that can only be used in emergency mode.
- Corrected weights;
* BR-20
- Decreased never-exceed airspeed.
* Spitfire Mk.Ia
- Fixed the top speed above 18,000 ft.
- Added pitot heat controls.
- Corrected (increased) Mk I's airspeeds at altitudes above 6K m.
- Corrected Mk II's speed performance at all altitudes.
- Corrected Mk IA 100-Oct Mixture Lever operation;
* Hurricane
- Corrected (decreased) airspeeds at all altitudes alongside Spit II.
- Corrected Hurricane boost indications. Previously shown +5.5Lbs Boost with full throttle, now properly displays +6.25 from Ground level all the way up to Full Throttle height;
- Corrected Hurricane 1 100-Oct Mixture lever operation. It no longer requires Mixture lever Forward to maintain smooth engine operation with Boost Cut out activated. Mixture Lever should now be properly held Back for Boost Cut Out operation;
- Corrected Hurricane weights. Please note that in-game weights are slightly different from those used in RAF documents, especially what the game calls empty weight. Our fuel is also slightly heavier. The weights in-game have been further finetuned to match desired performance.
- Decreased empty weight on the Hurricane improved turn rate, climb rate, and speed characteristics at all altitudes;
* Blenheim Mk.IV
- Fixed multiple issues with the engine model. The engine no longer overheats at nominal RPM.
- Decreased maximum allowed airspeed.
- Corrected the engine model.
- Corrected altitude performance.
- Decreased never-exceed airspeed.
- Corrected engine modes at all altitudes (RPM, boost, fuel flow, etc).
- Implemented smooth flap control.
- Changed the airscrew to two-speed.
- Corrected empennage values that created too much interference during take-off.
- Affixed springs to bomb bay doors.
* He-111 and Ju-88
- Corrected radio compass animations.
* Bf-109
- Corrected cockpit animations for trimmer and flap chains.
- Corrected flap model
- Corrected the flap sounds
- Corrected the pitot heat light.

VISUALS
* Added racing pylon models for air races.
* Corrected Z_Offset parameter in online missions. Mission objects will now properly offset based on mission designer’s input;
* Corrected radio beacon code online;
* Fixed rare crashes connected to improper Road or LinearObjectManager usage in custom missions.
* Fixed the plane label bug, where the label would hide behind the clouds;
* Corrected brightness for various light sources;

* Corrected the issue that sometimes disabled the country selection controls when connecting to a server;
* Corrected issues with some plane sounds online;
* Exorcised ghost planes;
* Corrected the behavior of “jumping” cars and some other vehicles;
* Fixed the issue where GamePlay.gpAirports() could return incorrect data.
* Added a new feature: user-made map labels that can be used in scripts.

PHYSICS & A.I.
* Fixed some non-working orders, removed others from the list. There are no more orders available to the player that the AI does not follow.
* Added a request for available targets;

Note about NVidia SLI:

The patch must go through official NVidia accreditation for SLI support to be officially enabled in drivers. The patch will only go through the process once it’s officially released on steam.

If you wish to bypass this process and manually enable SLI support, please go through the following steps:

1) Download a profiler utility, for example
http://nvworld.ru/utilities/sliprofiletool/

2) Export SLI profiles to a file

3) Manually edit the file by adding the following lines

must point to the actual location of the game’s executable. If you have installed the game to a different folder, please edit the line accordingly.

And now we think you’ve been waiting long enough!

The second part of our tonight’s update is the fresh beta patch.

We didn’t complete the readme in time. Please refer to previous updates to some info on what’s been done. We’ll provide a better readme next week.

Quick points:
Beta versions are incompatible online
FM work is far from over, we still have a long laundry sheet to go through.

Your mission for tonight: test all elements of the game. Especially focus on performance, any crashes, or any graphical glitches. Send all logs and crash dumps to ishevchenko@1cpublishing.eu

Have a great weekend!

Good day everyone!

The patch is ready! What we have today is a DX10-only alpha. DX9 support is specifically removed. If you are running DX9, do not apply the patch!

The main purpose of the alpha is to find and squash any remaining or new bugs, especially crash bugs. The most common of the infamous launcher crashes have been fixed, but a few very hard to catch bugs remain. On average, a full day of flying causes about 0.8 crashes, and our internal testing has not yet provided the crash logs needed to zero in on the issue.

And play!
Version number is 1.06.17582

We don’t have a complete readme at this time, but a rough list of changes is below.

Known Issues

• Not fully optimized: grass, clouds, and trees. Clouds cause constant FPS drop; grass and trees cause hick-ups. A few extra days of work for this, a few days for grass, few days for clouds, we felt that we could start open testing the patch without waiting for these changes.
• Texture cache failing to draw higher-res textures on close-up objects with lower settings on below-recommended video cards.
• Weathering textures on aircraft appear shiny in shadows.
• No damage decals on aircraft from small-caliber hits.
• The hit flash effects are temporarily turned off.
• Far and medium distance clouds are temporarily turned off.
• Text in dialogue windows in the mission builder may appear bugged with other dialogue windows underneath.
• The front line in mission builder and minimap is drawn incorrectly.

Changes and Improvements

Performance

We've performed a huge amount of work improving both average and minimum FPS in the game. Most recommended-spec machine will see a roughly double average FPS and a significant reduction in the micro-freezes that had previously plagued the game. Their frequency, duration, and overall FPS impact will be greatly reduced or completely redone.

Some of the changes include:

• Completely rewritten render pipeline, which reduced CPU load;
• Rewritten texture manager, reducing stutter when loading new textures;
• Moved landscape geometry generator to its own CPU core, reducing stutters;
• Optimized tree code, reducing stutters when moving across landscape or rotating camera;
• Moved grass generator to its own CPU core, decreasing stutters during low-level flight;
• Moved all building and vehicle damage models to be pre-loaded, rather than dynamically loaded when they are destroyed. This increased mission loading times and memory usage, and reduced stutters when blowing things up;
• Improved multithreading in many other aspects of the code, improving minimal FPS on most multicore machines.

Flight Model

We've performed a tremendous amount of work testing and improving flight models in the game, as well as improving various aircraft engines. We used actual pilot's notes and flight testing data during the process (thank you Sean!). Unfortunately some deeply-set limitations in the engine code do not allow us to minimize the margin of error at altitudes about 7 km (21,000 ft) where most aircraft begin to perform worse than their real-life counterparts. Fixing this requires more extensive code rework and will therefore only appear with the upcoming sequel. However at lower altitudes most flyables will perform much closer to real life. We also have to note that some aircraft, most notably Spitfire Mk.II, had better performance than the real thing. Others, especially their engines, had reduced performance. We've addressed these serious issues and made our planes fly much closer to the real thing.

Partial List:

G.50
Temperature models of the engine were wrong due to incorrect data. The engine could not get up to required power at all altitudes. We've also added +100 boost for WEP mode.

Spitfire Mk.II
The aircraft's speed performance was too good at all altitudes, sometimes 60 mph better than the real thing.

Spitfire Mk.I
Fixed the top speed dip above 18,000 ft.

Hurricane Mk.I
Speed performance was also too good at all altitudes, similar to the Spit II.

Blenheim Mk.IV
Had many problems with the engine model. The engine overheated at normal RPM, the plane could not get up to stated airspeed at all altitudes. Maximum allowed airspeed was too great, and the plane could get up to 560 mph in a dive. A huge amount of work was performed to improve the plane's FM and bring it up to speed.


Artificial Intelligence

Partial list:

• Fixed some non-working orders, removed others from the list. There are no more orders available to the player that the AI does not follow.
• Added a request for available targets;
• Turned off friendly fire for ground battles (improving FPS);
• Added the ability to query current waypoint for scripts;
• Told AI pilots not to commit ritual suicide when their leader crash-lands;
• Fixed out of turn take offs for AI pilots;

Sound

Partial list:

• Fixed two-engine flanger;
• Added detailed engine malfunction sounds;
• Added MG-34 and Bren Mk.II machine gun sounds;
• Added many other sounds: bomb whistle, bomb hit, atmospheric ambient, cockpit ambient, and many more;
• Improved and added engine sounds. For example, the Merlin family contains MerlinIII-RG-Hurricane, MerlinIII-RG-Spitfire, MerlinXII, and Merlin_III which all sound differently under various RPM conditions

Have a great weekend!
