ATI HD 4830 in perfect mode - landscape missing (black)

[CRO_Ante]

Thank you guys for helping me. This is my current setup that is working.

a) Catalyst 9.2 (with 9.4 I got problems in IL2 and other games too)
Best procedure for installing drivers is to uninstall previous drivers, restart in safe mode and than use DriverSweeper_1.5.5 to remove all graphic drivers.

AAx4 Box
AFx2
A.I disabled
Mipmap - Qualtiy
Vertical refresh - Quality
Adaptive AA - Quality
Open GL Settings - Triple Buffering

b) IL-2 Core DLLs - overwrite files in game dir with files from 02272008_core_dll.rar

c) conf.ini
