Navigational lights turned off during flight by AI planes
Pylon/bomb racks weight fixed -> better climb and takeoff performance for planes armed with external ordnance
Corrections in Flight Models (by Maddox Games)
MC-200 increased airframe drag-> reduced speed
P-11c corrected rudder roll response. Previously left rudder was inducing right roll and vice versa.
Ta-152C wing area corrected from Fw 190D-9 values (~1.2m²) -> slightly improved turn performance
DB-603L critical altitude increased from 9200m to 10200m.
Changes in Graphics (by Maddox Games)
Increased buffer size for stationary objects (buildings etc.) to prevent freezes under some circumstances.
Colors of water corrected for Water=2,3,4 modes. Now when looking down it is no more black/dark blue.
Optimized Shaders for Nvidia 8X00 series video cards.
Added a new mode for increased visibility distance. Visibility increased from 36 km to 72km under "Clear" and
"Good" weather conditions.
Note: This mode is not optimized for performance: (freezes and low fps are possible on low-end systems).
This new feature is available only in "Perfect" game graphics mode.
Also, there is a possibility to have problems with clouds and their shadows at far distances, due to some engine limitations.
Modify your conf.ini string in the [Render_OpenGL] section to use this mode:
LandGeom=3 (new mode is ON)
LandGeom=2 (back to normal mode)
Daidalos Team would like to thank all external beta testers from the following virtual squadrons for their hard work: Letka 13, 6° Stormo Virtuale, 102nd-YU, 352nd VFG, Kraken, and Sean
