To correctly run the game install OPF CD and do not launch OPF install Resistance CD and do not launch OPF Run 1.96 update. And now you can lunch OPF resistance or OPF.
For crossover games users if you have guild wars install you can use the same bottle the game remain playable but with most FPS than only with wine or new bottle created, probably due to the optimizations made by crossover team.
Do not set game resolution on panel but set it in game, because the resolution set is not applied in the game. All parameters in the flashpoint preference panel works, except game resolution, set it in game.
if your mouse don't work at the game start go to option menu with tab and enter. and activate the joystick in devices menu, it will work.
Remember, I don't know why but if you launch OPF before the full install of the 1.96 update, the game won't launch or launch with many graphic bugs.
