Finishing the game.
It requires native override for d3dx9_36.dll, otherwise the game will not run.
You still need to add the registry key to get 360º movement, or else the cursor will be constrained, making you unable to turn around:
I also noticed that the cursor's movement is extremely choppy, it was already not perfect on windows, but here, even though the game runs smoothly at high FPS, it feels like the cursor is moving at a very low refresh rate, this can be really annoying and it was able to give me headache.
Some fog/bubble effects are displayed wrongly, like the bubbles when you first get into the bathysphere, however this may be a problem with my graphics drivers as I have noticed that this issue isn't present for other people.
Physics look like they are running at a lower framerate from the rest of the game, again, this issue was present for me on windows, but on wine it is a lot more noticeable.
Loading times can be extremely long, maybe some other overrides will fix this, but I haven't got around to testing that.
My GPU is an AMD Radeon HD 6770, currently using the opensource drivers.
