Bug #: 32891 Summary: Counter-Strike : Global Offensive/Portal 2: Slowdowns after map loading/editing settings. Product: Wine Version: 1.5.22 Platform: x86-64 OS/Version: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: creepus0@creepus.org Classification: Unclassified
In Counter-Strike: Global Offensive and Portal 2, changing maps (or completing a test chamber in Portal 2) results in a severe slowdown. There are no errors in the developer console. There aren't any other Wine error/debug messages in the erminal window apart from the occasional WSAServiceLookupBegin error when Steam starts.
