Understanding FSO, FSE and flip presentation re. valorant

[99muppets]

Hi there, been trying to do some research about a few settings in windows 11, mostly with regards to valorant to eek out the best latency and performance.

I know there is recently a windows 11 setting that you can enable, which when games are run in windowed, or borderless windowed (Or FSO if im correct aswell?) means the game bypasses DWM which can incude latency.

Given this, for say valorant which is dx11, (no idea what default presentation model it uses), to eek out the BEST input delay, fps performance etc, what combination of settings should I be using? FSO enabled or should I manually disable it and force it to use FSE.

Furthermore, if I say wanted to play the game in windowed mode or borderless windowed mode, would the windows optimisation setting mean that windowed valorant would perform JUST as well as FSE valorant? Cheers, also if anyone could give me some resources for myself to test this would be great too.

If the game itself does not already use independent flip, Windows 11 will try to force it. More info on the flip models:

This only applies to DX11 games. DX12 games will always use independent flip so no conversion is required.

So you are saying, using fullscreen windowed, fullscreen, fso Off, etc.. doesnt matter for valorant on W11 ?

you don't need windows 11's optimizations for windowed games for valorant

valorant uses flip model natively with its windowed/borderless mode since 2022

it used to use the bitblt model for the windowed/borderless mode, and apparently its developer wasn't aware

they had a holiday project back in 2022 and they posted system latency results on twitter showing that fullscreen was significantly lower latency in their game, then some people questioned how they had implemented their windowed/borderless option...

and that ended with riot finally changing valorant's d3d11 windowed/borderless option so that it uses flip model. they also redid system latency tests and basically ended up concluding that now it's no longer necessary to use fullscreen and differences were within margin of error etc
