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.
