IL-2 Sturmovik Forgotten Battles 1.11 to 1.21 Patch

The current version (1.21) is not compatible with the previous versions of the game when playing via network. Both the server and client must have appropriate versions of the game (1.21) in order to connect.

Notes on the Patch Installation

This patch (1.21) may be installed over the previous versions 1.0 or 1.11.

New Positions

New Aircraft

Flyable:

- P-51D-5
- Ki-84-1a
- A6M5a

AI:

- C-47
- B-17G

Notes:
- The first production series P-51D-5 were delivered without the dorsal fin fillet. However, most aircraft had the fillet retro-fitted with a field modification kit. We have modelled the aircraft with the fillet. This will ensure skin compatibility with other D model variants. Also, in FB source code current limitation prevents us from replicating the real world P-51 fuel system.
- National markings on the fuselage of the Boeing B-17 needed to be moved forward due to position of the gun windows and due to the present aircraft coding system.
- A6M5 - the game models the version for the land-based runways.

New ships

Destroyer type 7/1944
M-Boat

Note:
These ships are made for the use on European maps for creation of new missions. Ex.: Destroyer type 7/1944 is intended to be used for the allied forces and M-Boat - for Germany.

New Maps:

Normandy1 - Large historical map based on the Normandy coast and Northern France. Pre-Invasion state.
Normandy2 - Large map based on Normandy and Northern France, with a non-historical Allied base off the French coast.
Normandy3 - Large historical map based on the Normandy coast and Northern France. Post-Invasion state with 18 temporary Allied strips.
Ardennes Summer - Non-historical medium sized summer map for online and offline play, loosely based on the Ardennes region.
Ardennes Winter - Non-historical medium sized winter map for online and offline play, loosely based on the Ardennes region.
Online8Islands - non-historical map featuring a "Pacific Theater" locale for online gameplay. Can also be used for user-made single missions and short campaigns.

Modifications

Changes and fixes in graphics: Perfect mode

- More realistic render of the water.
- Tuned the shades of the sea water.
- Eliminated chroma error of the water on ATI video cards (with disabled subtitles).
- Removed sun reflection artifacts on NVidia video cards with S3TC enabled.
- Improved visual appearance of the trees.
- Added an option to place better looking 3D trees in the towns and villages.

Notes:
For the new trees to render it is required that: you video card has no less than 128 Mb of RAM, and BIOS AGP memory (Aperture Size) set to no less than 128 Mb. Recommeded video cards for the option are GeForce 4, GeForce 5600 and newer, ATI Radeon 9700 and newer.
To see the new trees in towns:
Make sure you're running the game in 'Perfect' mode. In the 'conf.ini' file, in the section '[Render_OpenGL]' change the following line:
Forest = 2
to
Forest = 3
To disable the trees and return back to normal appearance, change the parameter back to 2.
NB:
The option is released in test mode. We're expecting video drivers update from the video card vendors to obtain full functionality of the mode. If you have less than 128 Mb of RAM on your video card, expect blinking triangle artifacts to appear on NVidia cards; on ATI cards you may see trees rapidly change their color shade and/or shape as you approach them.

Hints and Tips: How to Improve the Framerate
- Do not set the screen resolution to larger than 1024x768.
- Disable full-screen antialiasing.
- If you suspecting trees or forests to cause the framerate drop, try lowering the Forest parameter in the 'conr.ini' to 1, or even to 0 (that would make forest to appear in less detail, but faster render).
- Lower the objects visibility distance.

Il-2:FB list of recommended drivers

1C:Maddox Games recommends the following video card drivers to be used with IL-2:Forgotten Battles with the best graphics options. The sim may not function properly with other driver versions due to issues outside our control.

NVIDIA
Display Driver Version: 45.33
Release Date: October 9, 2003
WHQL Certified
http://www.nvidia.com/object/pc_winxp-2k_45.33.html

ATI
CATALYST 3.7
Driver Build 6.14.10.63787-93-030812a1-010735c

Tracks

- Corrected incorrect repeated playback error.

Sound

Corrected 3D sound engine by request of users, to prevent online sound cheating.

Users with a Sound Blaster Extigy card may need to deactivate the [Enables Extensions] from the Sound Setup of IL2:FB. When activated, some jerky sound may be heard when firing and changing views.

Users with the motherboard Asus A7N8X using the onboard audio card NVIDIA MCP2 (Chipset nForce2 SPP) may also experience these kind of sound problems, in that case turn OFF [Enables Extentions] in Sound Setup.

FM and other tunes of aircraft

Further tuning is performed on a line of aircraft:
- All Bf-109s.
- Me-262. Be aware that aircraft should accelerate slowly to maximal speed.
- La-5/7 series climb rate.
- Increased critical dive speeds for some aircraft.
- Increased roll rate of P-40 series.
- Corrected radiator-induced drag program module.
- Decreased damage durability of I-16, FW-190A-F series and some others.
- Modified the appearance of the metal-finished aircraft to appear more shining.
- Increased torque effect on a number of aircraft. Still not enough, but currently we have a limit for the greater and precise torque effect tunings.
- Fixed bug with automatic fuel mixture of P-47 series

AI

All types of aircraft keep better formation in wayponts with decreasing of altitude.

Weapons

- Added underwing payload variants for the P-51.
- Added ability to set up fuse timer for the Wfr.Gr. 21. To make the rocket operate as it was intended in real life, set the delay to 5.0 seconds.

Network

Added new types of messages in «eventlog».

1. When users switch On or Off wingtip smokes:
...:... turned wingtip smokes on at ... ...
...:... turned wingtip smokes off at ... ...

2. When users turn on landing lights:
...:... turned landing lights on at ... ...
...:... turned landing lights off at ... ...

3. When user changes the weapon or amount of fuel before take off:
...:... loaded weapons '' fuel %

4. When pilot successfully landed after bail out:
...:... (N) successefully bailed out at ... ...

5. Modified message 'was killed'.
Instead of:
...:... (N) was killed at ... ...
the new message is:
...:... (N) was killed by at ... ...
However, if the situation was generated by the aircraft itself (e.g., the pilot was burned) or bailed out pilot was killed with the hit from the ground, then the message will be in old format:
...:... (N) was killed at ... ...

6. When the aircraft was damaged but not exploded after landing:
...:... damaged at ... ...
This message is issued only once when the aircraft is on the ground (or not yet in air, or just landed).

7. At the moment of player disconnection:
...:... disconnected
The time of disconnection in the messages of client and server may be different due to naturally allowed timeouts for the connection loss situations.

Changes in Dgen and code of campaign, single and coop mode

When bailing out or crash landing over enemy territory, the player can now sometimes escape capture. It depends on the location of the front line and the closest enemy troops formation.

Other fixes and features

- Large custom skins (1024x1024) can now be used with the P.11c.
- Fixed a line of issues with incorrect radiator flap animations.
- Damaged MC 202 will no longer turn transparent.
- Added a line of USA and Great Britain regiments to use with the B-17.
- Added Japan to the list of available countries to use with added Japanese planes. 2-letter code for the custom regiment files is “ja”.
