Here's a snipit of the config file for SoftTH. Might be worth looking into the multiple methods it uses.

Code:
[Direct3D]
   ; ** Advanced setting for Direct3D games **
   ; lensCorrection: Lens correction, set to 1 to enable support. >1 to enable by default
   ; lensCorrectionEdge: Lens correction edge offset
   ; hideNondefaultDevices: Hides all but the default adapter from the game
   ; forceHorizontalFOV: Forces horizontal FOV to be three times as wide
   ; forceResolutionWidth/Height: Forces device to be created with this resolution
   ; force16bitDepth: Force game to use 16bit depth buffer, can improve performance and reduce memory use
   ; sleepBeforeRead: Time in ms to sleep before reading back buffer data from video card
   ; useMultihead: Uses multihead features of primary card if available, can increase performance and reduce memory use
   ; delayedPresent: When useMultihead enabled, delay primary monitor present to sync with secondary head
   ; d3d8dll: Path to D3D8.dll/D3D9.dll to use or auto for automatic (system32 dir)
   ; altResetBehaviour: Do not reset lost main device after secondary device initialization (WDDM crash workaround)
   lensCorrection=0
   lensCorrectionEdge=0
   hideNondefaultDevices=0
   forceHorizontalFOV=0
   forceResolutionWidth=0
   forceResolutionHeight=0
   force16bitDepth=0
   sleepBeforeRead=2
   useMultihead=1
   delayedPresent=0
   autoSquash=0
   altResetBehaviour=0
   d3d8dll=auto


My curiousity is the methods used for lensCorrection, lensCorrectionEdge, forceHorizontalFOV, autoSquash?

forceHorizontalFOV attempts to force a games FOV to expand by 3 times. Better do use a games own settings if at all possible.

autoSquash attempts to detect when only 2D elements are on screen (like menus), and if it does, squishes the output to the center monitor. This helps with stretched menus in games like Bioshock.

Lens correction is the one you want. It can do pretty much what Racer_S has done in photoshop, but with one important difference. It can do it without stretching the HUD. The effect is only applied to 3D rendered elements.

Sure, if you want to throw your your TripleHead2Go and join the SoftTH club :wink:

it was an easier setup and is compatible with more games. =P

"Easier to set up" is debatable. Look at all the problems some people are having with the TH2G and specific drivers, and the fact that you have to make sure your screens support 57Hz if you want to run 5040x1050.

SoftTH doesn't have these hardware and driver compatibility issues, and supports resolutions upwards of 7680x1600, but it only works with DirectX8 and DirtectX9 applications (OpenGL version pending).

There's always a catch, no matter what solution you use.

I thought it was common knowledge SoftTH did this. I was playing with it before I got my TH2G 6mths ago. The Lens Correction works (though like Racer-S's solution it zooms the image) and IRC it can be adjusted on the fly to allow some compromise.

It wasnt enough for me to put up with lower colour depth and obviously laggy sidescreens as well as obscure per game INI settings to keep it over a hardware solution like TH2G. I would however be interested in something that added Lens Correction to TH2G!

The side screens have never been laggy with SoftTH as long as you have enough bandwidth for your two video cards to communicate with one another. You're also not forced to run lower bit-depth on your side screens, you can set it to 32bit color if you want. I'm using a PCIe 16x 8400GS to run one of my side screens, which seems to do the trick just fine.

There's also the CUDA based frame copy method inroduced in the latest version for Nvidia cards, which pretty much eliminates the possibility of any side screen lag and boosts performance hugely.
