why do games run better on borderless mode?

[Ossie]

Lately, ive noticed that changing games to window borderless or using borderless gaming (for windowed mode) makes my games run way more smooth, For example, while playing yakuza 6, i had horrible tearing no matter the resolution/graphic settings i used, until almost at the end of the game i thought about changing to window borderless and when i did the performance was so much better.

Same as rise of tomb raider, while using fullscreen & exclusive fullscreen mode id get tearing and frames from 40 to 50ish but after changing to windowed mode and using borderless gaming it runs without framedrops, no tearing and my gpu is not making any sound at all (compared to the fan being so loud while in fullscreen)

Could someone explain please why does this happen? id really like to know. Thanks !

matches ur display resolution better

No idea. But I used to notice big differences between Fullscreen and Borderless Fullscreen Window. Despite apparently doing the same thing there must be differences between the two modes.

When running a game in borderless mode, DWM (Desktop Window Manager) has control of the display, while the resources of the graphics card is shared between applications.

When running a game in exclusive fullscreen mode, the application has full ownership of the display and allocation of resources of the graphics card. DWM is not involved.

Desktop Window Manager applies VSync to all windows, by default.

in windowed windows also needs to keep updating desktop and some other background stuff

as bananarama says, DWM.

also DWM is a bit like fast sync, which applies a more low latency/adaptable sync, under which your frame rate can exceed your refresh rate

my personal favourite is just very high refresh rate, in exclusive fullscreen, with no sync and frame rate cap from engine/RTSS/nvidia drivers. I much prefer no sync 240hz to vsync, fast sync, borderless, freesync or even gsync (tried them all).

it's hard to see tearing on high refresh rates with nosync, same as high frame rates on low refresh rates (like 400 fps on 60hz, the visual appearance is similar to 60 fps on 400hz)

totally the opposite.
exclusive full screen will always run better then boarderless windowed/windowed mode.

Most games ive tried in borderless usually perform slightly worse than fullscreen, or there is no change, but you do get the smoothing vsync feeling in borderless which I can't stand on some games.

makes sense, i started using fullscreen lately for "better" performance but its honestly the opposite, i dont get how a game runs worse and my gpu goes under more stress on fullscreen and its so quiet while in borderless while everything runs smoother, but well, it is what it is. thanks!

Sounds like you never enabled vsync for full screen in the GPU driver. Are you using a different resolution in windowed vs full screen? Do you have graphics enhancements enabled in full screen that do not run in windowed?

Should take your own advice. Games run, on average, better on full screen. Feel free to google it, or listen to the others who have explained it... Any experience you have to the contrary is yours and equates to little more than an opinion, which in this case, goes against the vast majority of others opinions and experiences.

I run games exclusively in Borderless because I have more than one monitor and multi-monitor systems behave better when you use Borderless. It is a choice though. I would just use whichever mode you prefer.

don't know?
as others have said, exclusive full screen runs better due to the fact windows isn't rendering the desktop...
what are you even talking about dude.

borderless windowed has no reason to "give better fps"
it may feel smoother to you due to the windows vsync (you also get more latency)
compared to full screen (unless you enable v-sync or have a free sync/ g-sync monitor that adjusts the refresh rate on the fly, making it feel way better.While also not rendering the desktop giving you 1-3+ fps )

your thread made no sense in the first place.

you said it best

if you dont know, just dont post.

ohhh okay so getting better performance, less stress from hardware and no tearing makes me a liar, yeah im totally lying and i just created this threat because i wanted to come up with some ♥♥♥♥♥♥♥♥, and of course i dont know why that happens, thats why i asked for answer. Everything you mentioned was the most basic information, i would have kept quiet instead of posting trying to act smart.
