I was reading the PC FAQ and they say you cannot turn AA off, and forcing it off via GPU drovers results in visual errors. Thats pretty lame for multi-monitor usage. But i also read that the multi-mon works great.
Apparently Volumetric Lighting takes a huge hit on performance, as SSAO does. And there's already a patch.
After patch gives some folks a sweet 2 frame per second. if this happens, just set 3D video card settings back to default. I think this only happens to ATI. Amd, whatever.

Alan Wake PC Support FAQ and Known Issues FAQ
This is a copy from Remedy's forums - we will aim to keep both up to date, but the "original" version is here: http://forum.alanwake.com/showthread.php?t=7759
IF YOU HAVE PROBLEMS
We would love our games to work for everyone, and have done our best to test the game well, but the amount of PC configurations makes this a difficult goal to accomplish. We will do our best to help solve problems, but have limited capacity for direct e-mail support. We would hope that you would do as follows:
Please read this FAQ to see if your problem has been solved already. You can also try to search this forum for solutions.
Update your graphics card drivers. This solves 90% of problems typically. AMD Driver download & NVIDIA Driver Download. We have tested extensively with AMD Catalyst 12.1 and Nvidia 285.62 drivers.
Please post a forum thread to the Alan Wake Help and Issues board - we have an active community that likes to help, and have Remedy staff in hand to answer and help as well. Remember to add your computer information or attach a dxdiag text file with the forum post.
GENERAL
Command Line options
The game supports a few command line options meant mainly for troubleshooting. Warning: for advanced users only. Many of these options can be selected from in-game menus and we recommend doing that instead.
You can enter them by right clicking on Alan Wake in the Steam Library and choosing Properties. From there go to "Set launch options".
-w screen width (e.g. -w1280)
-h screen height (e.g. -h720)
-window force windowed
-novsync disables v-sync
-showfps shows a frame rate counter on screen
-forcesurround forces 5.1 speaker mode
-forcestereo forces stereo (2 channel) speaker mode
-nosound disables sound
-cleancloud deletes your save games and settings for Alan Wake from Steam Cloud
-noblur disables the in-game vector blur
-locale=xx forces a selected locale. This should not be needed as you can change it from the Game Properties in Steam. Note that you have to have the locale files downloaded from Steam and that happens only when you choose the language you want to play in from Steam.
GRAPHICS
SLI & Crossfire Support
Due to the way the graphics engine has been constructed, it does not work well with multi-GPU configurations out of the box. AMD has made Crossfile profile for Alan Wake that enables 65-75% performance boost on Crossfire, but Remedy has not been able to test this yet.
If you have problems, Remedy recommends disabling multi-GPU mode for Alan Wake.
Trees flickers after "alt-tab" to desktop and back to game on Windows XP / NVIDIA
In some rare WinXP & NVIDIA graphics configurations, trees in the game start to flicker after popping out of the game with alt-tab and then when resuming gameplay. We haven't been able to track down the cause but the should be avoidable by playing in full screen and/or dropping some settings like SSAO or shadows to medium quality.
Multi-screen support
The game supports 3x1 EyeFinity configurations. 5x1 and 3x2 configurations are not supported.
On Windows XP, we recommend disabling NVIDIA nView Span mode as the game may not start. Recommend using Windows's built in "extend desktop" feature instead. If you wish to keep Span on, you can play the game in window by using command line parameters as described above.
Stereoscopic 3D
Remedy has only tested the game on NVISION2 3D. To run smoothly we recommend a fast graphics card. We also recommend setting 3-5 bars of stereo separation for best experience. Remedy has not been able to test/confirm if we run on AMD HD3D.
AUDIO
Windows XP - IDT audio on Windows XP does not work correctly
It's possible sound is not heard from all speakers. It was noticed during testing that if the IDT control panel is used, it resets Windows speaker configuration to 7.1 - making the game think you have 7.1 speakers. This may make the sounds work incorrectly. This is a driver issue rather than a bug in the game. You can use "-forcesurround" or "-forcestereo" command line options if needed.
CHEATS
There are a few cheats built in to the game that will be revealed soon.
SAVE GAMES and SAVE DATA
Alan Wake saves data to your "My Documents" folder (e.g. C:Users<username>Documents) under RemedyAlanWake. This contains resolution.xml and if enabled possibly some debugging information. Game regenerates these if not found. Your save game is stored under your Steam profile, and mirrored into Steam Cloud if that option is enabled.
Alan Wake does not store anything in your computers' registry. Steam uses registry to keep track of first time installation information and such issues.
