SO devs say that exclusive fullscreen has no performance advantage over borderless. Well that may be true in sheer number of fps, but i couldn’t get the freesync to work with borderless. So i launched the game from the free Razor Cortex app and ticked the “game desktop” mode. Which is basically Razers word for launching your game in Exclusive fullscreen. And surprise, surprise Freesync now works without problems.
Game is still catastrophically optimized mess, and the latest beta drivers from AMD keep crashing. But at least now with freesync working.

Nice find thank you. We need a dedicated fullscreen option.

“Devs say”. Hey Devs, do you use my setup, NO. Do you sit here and watch a game run like A%% while trying to play in a windowed fullscreen (Which by the way DEFINITELY has performance issues) NO. I didnt think so. How about instead of just not fixing it when clearly some individuals have a problem. Just add the option. WTF.

I’ve never seen a game before include both so much and so little at the same time and yet Halo Infinite actually manages to do both exactly the way no one asked for. I’m glad they offer so many options for varies things but then we’re missing a critical option the fullscreen mode that’s in 99% of games and they refuse to put it in the game even though people are clearly asking for it.

How do you enable the exclusive fullscreen mode in cortex?
Is there any perceivable impact on input lag either positively or negatively?
I feel like this is a virtual version of playing other consoles through your Xbox’s “input” jack.
Something else they haven’t thought of is people running lower-spec hardware with higher resolution monitors. For example, I have an RTX 2060 plugged into a 4K monitor (when it’s really a 1440p GPU), and with borderless fullscreen, I have no option but to play in 4K which even on lower settings still gives me potato FPS. 343, Give me the option to run fullscreen and change the resolution for GOODNESS SAKE!!
FYI game desktop mode is under the boost tab in cortex
That sucks. Have you tried the in-game resolution scaling @ 67% (roughly 1440p?) That’s got to boost FPS unless vsync/framecap is locked there or in NV control panel? Or set min framerate to 60 or something?
If not, lowering actual Windows’ desktop resolution to 1440p will let halo recognise that as native and will run at 1440p 100% scaling. I just tried that and my FPS jumped significantly. Might be worth a shot.
If that second option works you might want to readjust refresh rate and display scaling of course so it doesn’t look like -Yoink!- on your 4k monitor. Anyway maybe that’ll work just my 2 cents.
