None, I have not come across any issues at all, extensive testing has yet to be performed but it seems that this performs much better than the original Shadow of Chernobyl.

Have you ever dreamt about playing the old, forgotten S.T.A.L.K.E.R. ? We were amazed by GSC's work when they released the first S.T.A.L.K.E.R. screenshots in 2002. The old design, and atmosphere was stunning and we couldn't believe our eyes. Later in 2005 things has changed. They redesigned almost all old levels. Some of them became smaller, simpler (still nice, but different), and some levels were removed. After the release in 2007 we played the game a lot, and quickly noticed that some areas are missing. We opened forums, and talked countless nights about those for almost a year. Nowdays we could say, we have a full vision about GSC's old levels, due to the collected materials, videos and forgotten screenshots. We decided to remake those stunning areas, maybe they won't be the same, but we will try everything to make them look really nice, as we always wanted to see them. In early 2009, GSC released a build from 2004, which contained many old materials. We used some of the sdk objects for the level remakes, but adjusted (and bugfixed) them for our liking, also we didn't throw out our own levels. So expect to see our own Darkscape, Dead City, Rostok Factory and some more in Lost AlphaAlso need to say, Lost Alpha addon is not just about levels and levels. We will try to make a somewhat, but not fully restricted alife, and deliver a lot of new, never seen features, among with some old ones, which many people wanted to see for long. If you are interested in, check the Features menu for FAQ, Interview, Features List, and many more. Also do not forget to check the gallery, and the movies. All comments are welcome, also we are glad to see suggestions too, however at this stage those won't be considered.Thanks for your understanding!Finally, we would like to thank to the old Stalker Team this wonderful game. Without them, S.T.A.L.K.E.R. wouldn't be a "dream-game".

Site header image and icon foreground by Jeremiah Humphries.Thanks to Stephen Shannon fort finding the post with directions to extract the correct msvcr.DLL from the vcrun2012 package to make this port possible. I extracted the files necessary from the vcredist_x86.exe and placed them in the drive_c/windows/system32. I did not perform any overrides on any of the .dll files placed in the folder.Version 1.1 of the wrapper is much more comprehensive port for Lost Alpha. I compiled a Wine 1.7.19 engine that utilizes a wined3 patch written specifically for 1.7.19. I added many changes to the user.reg file which significantly improved the performance, I am now able to run this game at native resolution, although I choose to reduce image size for image quality, the game can be run on full dynamic lighting [dx9] with minimum settings on my Macbook 5,2 (sys hrdwr in sidebar) which is actually pretty surprising considering the detail in the maps. The loading time for the game has also been vastly reduced with this engine.Sometimes the sound will stop, simply pause and then un-pause the game to restart the sounds (ambient, musical and otherwise) Sometimes voices will not continue when trying this method.*wrpr_v1.1WInetricks used - d3dx10, d3dx9, remove_monoAdded Registry changes:[Software\\Wine\\Direct3D]"AlwaysOffscreen"="enabled""CSMT"="enabled""DirectDrawRenderer"="OpenGL""MaxShaderModelGS"=dword:00000003"MaxShaderModelPS"=dword:00000003"MaxShaderModelVS"=dword:00000003"OffscreenRenderingMode"="fbo""StrictDrawOrdering"="disabled""UseGLSL"="enabled""VertexShaders"="hardware""VertexShadersConstant"="256"[Software\\Wine\\DllOverrides]"*d3dx9_34"="builtin""*d3dx9_35"="builtin""*d3dx9_36"="builtin""*msvcp120"="native""*msvcr120"="native"*wrpr_v1.0WS9Wine1.7.17_WGL_surface_ext engineWinetricks used - d3dx9Click on the link above and download the GSC/Dezowave S.T.A.L.K.E.R.

It is highly suggested that you remove the redistributable folder completely. All the components necessary to play the game are already installed into the wrapper. If you decide to move the folder out it will cause an error at the end but it will not impact the already completed install.
