What are the disadvantages of that program?
Latency, the fact that you must manually drop injection dll's into the game folder and the fact you have to manually configure every game with a text file. dll injection like this is seen by some game DRM as a false positive to cheat injections. If you play a game that you're always multiplayer with and it has anti-cheat detection for the game, be prepared for the possibility that you'll have a false positive ban. Also the compatibility is problematic. It's very much a case by case basis for compatibility. This isn't a solution that is universal, you have to manually configure everything in order for it to function.
On the positive side, you can set up any exotic display configuration you want to. duniek misses the real advantage of SoftTH by only showing wide spans and video walls. SoftTH can slice up the layouts to any thing you want. Configure the displays in a + or an H layout if you want to. This is huge potential for simulator games. You can even do nonlinear and non-adjacent display configurations with SoftTH by assigning the display content to be a slice from anywhere in the original rendered 3d artboard. You can also span any video ports out available on all cards. You can even use it to force fake resolutions and FOV onto displays like pushing 8192x1080 to a single 1920x1080 screen.
Some of these advantages introduce latency, sync and tear issues into the configuration. You can do anything you want to with SoftTH and exotic layouts, but it comes with a price of bottlenecks if you're spanning video cards and pushing absurd pixel size.
duniek needs to recall I was using SoftTH to do exotic things even back in 2007, so I do know what I'm talking about. Problem is, he threadjacks totally off-topic around here with SoftTH in Matrox TH2G, NVIDIA Surround and AMD Eyefinity subforums. :wink:
My suggestions from 2007 that eventually turned into SoftTH 2.0:

Here is a pic of the first 5x1 gaming setup I did in 2007. TH2G Analog and SoftTH. Talk about old-school 5x1. This was the first documented example of SoftTH ever using more than 3 displays. duniek has an advantage that SoftTH finally implemented all my old suggestions and enabled as many displays as you want now.
There are those that actively seek to have new capabilities implemented and there are those that merely enjoy their use. I like to believe that I'm the former, not the latter.
None of this remotely has anything to do with the original topic though.
