S.T.A.L.K.E.R. : Clear Sky Patch v1.5.06

Deep Silver has issued a new patch for S.T.A.L.K.E.R.: Clear Sky, bringing the official prequel to the survival FPS game S.T.A.L.K.E.R.: Shadow of Chernobyl to v1.5.06. The patch includes balance tweaks, bug fixes, and adds DirectX 10.1 support, for which ATI released a hotfix earlier today.

• Added MSAA for alpha-tested objects ("alpha-to-coverage" for DX10.0, custom "alpha-to-coverage" for DX10.1 for better performance, native DX10.1 implementation for better quality). 
• Added new quality level for sun-shadows (ultra) for better picture quality. 
• Added new min/max shadowmap technique (which takes advantage of DX10.1 when available) allows to speed up high quality sunshafts rendering for top video boards and high resolutions. 
• Added high quality sunshafts acceleration for DX9 renderer

Note: 1.5.04 and 1.5.05 saved games will be compatible with new patch.
