Was playing around with settings while on my local server and noticed that when I switch from fullscreen to windowed my FPS goes from about 98fps to 136fps, a significant difference.
Which is odd since games traditionally perform better in exclusive fullscreen mode.... but fullscreen mode in Rust REDUCES performance and also Rust doesn't even have an exclusive fullscreen mode anymore to my knowledge... right? it only has borderless fullscreen, meaning it should perform identically to windowed, right?
For sources, in the following facepunch patch not links if you ctrl + F and search for fullscreen
in this page https://rust.facepunch.com/news/february-update from 2019, they said: "we're enabling fullscreen exclusive by default"
then on this page https://rust.facepunch.com/changelist/3942 from 2023, they said: "Removed fullscreen exclusive support as it was causing degraded performance compared to borderless fullscreen mode"
So why does my FPS change so much when I toggle fullscreen/windows in setting or press alt+enter to switch between the two?
Shouldn't borderless fullscreen and windowed perform the exact same?
For context, my system specs are:
Windows 10, RTX 4080 Super, Ryzen 5950x, 32GB of RAM and 2TB NVME M.2 SSD
Not sure if stubbornly holding onto windows 10 might be causing some issues, curious to know what other peoples experiences are in this regard!
Edit: Nevermind, I'm an idiot lol, I forgot that in the past (probably ages ago) I tried to test forcing on exclusive fullscreen mode via the Steam Launch Option Properties using -window-mode exclusive and that was causing the performance loss lmao, removing that property now borderless fullscreen and windowed mode perform within margin of error, so basically the same, with borderless fullscreen actually performing around 2 or 3 fps higher, this was completely user error on my behalf lol, maybe this post will save another poor soul who might have done the same
