Hi Imusrt!
Thank you very much for your help! I have been through your blogposts and details and they are fantastic! Thank you very much! They got me started on this thing since I had kind of given up when I found out PLP eyefinity was not supported.
I have not tried out SoftTH since I read it only works with DirectX 9 and most of my recent games are newer. ShiftWindow I first tried the original version then found the version you point to for Windows 10 (I am on Windows 10). It works quite well.
WinShift and ShiftWindow is the only solution I have gotten to work so far successfully (I know depending on game engine). The games that work will react to WinShift's resizing of the window and change the in-game resolution to fit the new window. Successful games I have gotten to work using this method are
Star Wars Battlefront (works perfect borderless window)
GTA V (will only work in non-borderless window - if I use borderless window it will not be affected by the trigger from WinShift)
Star Wars The Old Repucblic (non-borderless window)
Might and Magic Heroes VII (new game reacts perfectly in borderless window - resizes and even say in options that it runs 4960x1600)
So to the games that I have no success with, where your details of the game describes that it works perfect just by changing the ini file:
Crysis 3When using WinShift it will resize the window, but the game engine does not change the resolution so it will stretch a 2560x1600 to the 4960x1600 window.
When I modify the ini file as per the instructions, Crysis will open a black 4960x1600 window that fills all 3 screens, then before it starts rending the intro/menu it will change the window to a 2560x1600 window that only fits the center screen. Then I am back to point 1.
I have tried read-only on the file but the result is the same. Without read-only Crysis 3 will change the ini file upon exit, when read-only it of course cant so the file will stay as I changed it, but it will still resize window.
EDIT: I just found that I can change the width resolution in-game through the console and make it work! It will still launch-switch to 2560, but once in-game I can change it back through the console.
Assassin's Creed SyndicateI haven't tried the older DirectX9 versions of AC as I am playing the latest installment.
The window will resize, but content will stretch and resolution does not change.
Changing AC.ini does not matter, same with read-only. It will detect the screen being used and adapt to it. Even changing to smaller resolutions will still auto-switch the window to a 2560x1600 window.
World of WarcraftI have seen on the net people making it work with SoftTH, but the engine has changed to DirectX11, so I tried without
WinShift will resize the window, but engine keeps resolution and stretches
Changing config.wtf does not matter.
EDIT: I found out that putting a lower resolution (2480x800) in window will allow it to boot up the right aspect ratio, which can then later be pulled out to fill all screens. I can't see if it switches to 4960x1600 or still run the lower resolution.
I know it is different engines, but so far I have had no luck getting a game to work just by changing its config file. The game will detect the max resolution and switch to it upon launch. That was why I wrote the question because according to your blog and other posts it seems that people can get their games to spread just by changing game parameters, but I haven't had any luck trying that. The only thing I have had success with is WinShift.
