protontricks vcrun2005 physx win7; disable openal portaudio backend and force it to use alsa

Missing textures occur, if openal is used with portaudio backend, which defaults to Jack as audio device. This leads to _DN_FLUSH to be set, which will remove all textures in the menu except the player and plains in menu and everything including the player in-game. Also singleplayer startup will stop with a blackscreen. This has been tracked by Wine Bug #52393 and introduced in commit f99d307a3e1f9beb7fd9dc8892b5cfabbabf816b (5.0-rc3-23), which did unhide the bug from openal.

Without a virtual desktop, the game may lead to missing video signal to X on Nvidia drivers.

The game crashes with any proton/wine version on game start (after main menu), until it is started with 1080p resolution. Afterwards it will run in higher resolutions. Occasionally the game might crash on area changes.
