--- Comment #48 from Jan Havran havran.jan@email.cz --- Still an issue with Wine 4.0 rc2 while it is fixed in Wine staging (but since staging 3.9 there are some rendering issues, see bug #45278).
For those interested in testing the game with Wine testing (no staging), here is a list of missions playable without Wine-staging or VC-Starter:
Vietcong campaign missions: -Swamped -Briefing for Twisty Track Drive -Twisty Track Drive -Briefing for Po Tlong Karai -Flight to the Po Tlong Karai -Briefing for Under siege
Vietcong Fist Alpha campaign missions: -NuiPek after attack
Quick fight is working for VC side only.
