--- Comment #2 from Alexey Loukianov mooroon2@mail.ru 2012-05-28 00:18:53 CDT --- Looks like in Wine 1.5.5 built-in implementation of d3dx9_XX had been fixed to a state when Limbo could start up and produce a properly rendered picture when using built-in d3dx9_43.dll and native d3dcompiler_43.dll combo.
Having both dlls set to use built-in libs no longer results in "Vertex shader error" message, instead the game starts up and seems to be working correctly but does not render anything (I can hear in-game sounds and navigating in-game menu blindly also seems to work). Logs shows a lot of fixmes, mostly related to stubbed procs in d3dcompiler_43.dll. Just the same behavior happens with native d3dx9_43.dll (or native d3dx9_36.dll) and built-in d3dcompiller_43.dll.
Having both dlls set to native works OK just as it had always been.
Dan, maybe it's time to re-test NFS:World to check if something had improved recently?
