Alt + Enter What does it do?

[Wali763]

Ive read many times about Alt+Enter to make the game fullscreen. When I tried it, it never seemed to make a difference for me though.

 

Now with 2.5.6 I had to disable the fullscreen-checkbox in the settings since this would often freeze the start of DCS.

 

Now Ive tested a bit with Alt+Enter again and found something strange.

 

I do use a 1440p-monitor with 144 Hz, that supports Freesync and Ive set my Nvidia videocard to G-sync-compatible (=> Freesync). I dont see a big difference (which may be up to TrackIR) but it seems better, than without Freesync because there is not tearing, that otherwise is only just visible in fast up-and-down head-movements in the Cockpit. Only drawback of Freesync being, that I get some slight flickering on the loading-screens and the main-menu, but not in the cockpit.

 

Anyway, my monitor also has a frame-counter and when I enable it, one can easily see, that the fps on the monitor are the same as the ingame-fps-counter or in MSI Afterburner. So eg 87 in the ingame-counter and 87 on the monitor-Counter, constantly going up and down.

 

But when I hit Alt+Enter, the flickering in the main-menu is gone, but the frame-counter of the montior then shows fixed 144fps and also later in the mission. Also some minor screen-tearing is perceiveable again. Hitting Alt+Enter again and Im back to the variable fps as before.

 

Strange. Is Alt+Enter also used by the Nvidia controlpanel to turn on/off the Freesync/G-sync-compatibility??

 

Is Alt+Enter still needed in DCS?? It never seemed to have worked for me anyway, so I used it only for testing.

Alt-Enter switches between borderless-windowed mode and the actual, proper full screen. It used to be needed in DCS between 2.1 and early 2.5-ish because ticking the full screen box in gfx options didn't quite work properly back then. Then it got fixed and worked OK for a year at least... to become broken again in 2.5.6. So I have to use it again to have my V-sync operational and avoid screen tearing - I own an ordinary 60Hz monitor, though. No idea how the situation looks with 120+ Hz hotrods.

Ok, thx, for that post, Was quite helpful and I think now I get it.

 

 

In the Nvidia-Controlpanel, I can choose at the G (Free) -sync-compatibility settings if I want it only for full-screen or also for windowed mode. I just have checked the first one. So when I hit Alt+Enter I go from fullscreen (with Freesync) to windowed mode, which does not Support Freesync because of my settings.

 

 

So after starting 2.5.6 Im in fullscreen-mode even the checkbox in the graphicssettings is unchecked. Go figure.
