Ralackk: In the advanced options ingame try turing off HW vertex processing.

K_Dub: I can't find the advanced options ingame. I can only get to regular options via the main menu and ingame pause menu.

Namur: EDIT:
I edited out my answer as it was the same answer given by Ralackk.
The boards froze on me again so when i posted, Ralackk's post 'wasn't' here.
Using the boards it's getting silly...

Ralackk: I hope it has something to do with increased traffic to the site over christmas and will go back to normal soon. Pretty much have to answer something and then come back much later to see if it came up at all and if anyones replyed. As it is you will have a new message post but won't beable to find it until this goes through :P

Ralackk: For the hoover craft lag turn the water settings down to lowest. I don't know what it is but they lag way worse then they should, they brought my 6800 ultra to its knees. Once on lowest its normally fine though.
As for sounds, I have a few sugestions. If on windows xp run dxdiag and change sound hardware acceleration or if you have a dual/quad core system run the game on a single core. You can do that by ctrl-alt-del to bring up task manager, find the games process in the processes tab and right click it. Then set the affinity setting to core0.
If neither of those solutions work could you post your system information and OS please?
Edit:
Just figured out what HNY stands for, man do I feel stupid, that took me hours. Eitherway Happy New Year Namur

K_Dub: Dude! Really appreciate the help! Game's runnin' great now! Sure the water may kinda look like crumpled paper now, but who cares!? This game's fun as hell! Again man, thanks for the help!

Unfather: Just wanted to contribute my two cents. I'm very careful to edit my graphics settings for performance without exchanging much visual fidelity and this was the best route for me on a Toshiba Satellite C855-S5111 in Windows 8 (this also fixed the terrible graphic flickering and tearing I had initially):

- Go into Advanced Settings of Beyond Good & Evil Settings panel
- Check Manual compatibility settings
- UNcheck HW Vertex Processing
- UNcheck W buffer

That should fix the graphics problems as well as make the game playable. For the slowdown I experienced in heavily lit areas like the Main City and Slaughterhouse:

- UNcheck Multi Vertex Stream

For overall increased performance, lower the anti-aliasing slider.

NOTE: Those familiar with tweaking graphics settings know that typically there's a pretty big performance payoff for lowering general Water detail settings and Shadows quality. HOWEVER, I found that to be untrue for this game with my setup. Despite some pretty good reflection quality in the water, I received almost NO noticeable framerate increase from dropping these settings even to their LOW and OFF settings, respectively. Same with Flare, but that wasn't a surprise.

thebream: Thanks a lot!
I unchecked HW Vertex Processing which fixed all the flickering graphics.

And by unchecking Multi Vertex Stream, this fixed the huge lag I suffered when I entered the city. Now I don't have to lower the water detail to fix the lag.
