once the game installs you have to edit the launcher: add the -dsound flag to it, otherwise you won't hear any sound.
Do NOT set Wine to emulate WIN98, this will cause Operation Flashpoint crash upon loading.
Apply these registry settings in your Wine instance. Verify them, as you may need to set these manually within the regedit of wine.
Start the game with "wine FLASHPOINTBETA.EXE -nosplash [-mod=@YourMod] .."
Once the game started, start a wine task manager with: "wine taskmgr" and set the CPU affinity for the flashpoint process to a single CPU. Other wise there will be massive lag in multiplayer after a few minutes.
