I did some work on getting triple-head going properly in DCS: World 1.2.4 (7680x1440 with three 2560x1440 monitors). I’ve tested that everything seems to work fine with the A-10C Module. Also looks fine with the F-15 (so probably everything in Flaming Cliffs 3), and the Ka-50 Black Shark. The Ka-50 viewpoint is a little buggy and will try and zoom out a LONG way when you enter, so just press * to zoom in until it looks normal.
In order to set up, you’ll need to do the following;
- Apply the diff file from here to your DCS World setup. It’ll go and change a couple of files in minor ways. You can also get a ZIP of these files already changed suitable for DCS World 22.214.171.12413.167 from this link: TripleheadFOV-126.96.36.19913.zip
- Copy autoexec.cfg from here into your
- Copy SnapViews.lua from here into your
The diff allows use of customized snap views, and sets the default external viewing angle to 120 degrees (maths as to why this is right can be found at this link). It also hardcodes the screen width for some UI elements to 2560x1440, and pushes the radio chatter windows across one screen so that they render on the middle screen and not on the right. And lastly, it modifies Server.lua to allow the widened FOV for the Ka-50.
The autoexec.cfg sets the maximum fps to 60, to avoid issues that tend to happen with microstutters on SLI. The SnapViews.lua contains recalculated viewing angles for all default snap views such that they are corrected for triple-head FOV, as per my prior post on the topic.
