-windowed -noborder
works for a lot of steam games, not just source games

This obviously isn't for the games which those well known launch options work on

BenQ options > Display Mode > Fullscreen

Not everyone has a BenQ monitor

you'd almost think that there's a reason for people to (want to) use windowed mode.
i guess the developer(s) of this tool didn't realize there was such a thing like fullscreen mode,
maybe you should inform them

Wouldnt making the game windowed, then using fullscreenizer be better?

Wait why would you pay for this, I have a program with the exact same icon and use it to play terraria in windowed borderless?

I had an autohotkey script that did this but I haven't used it in a while

Did you even read past the steam store link?

You now have an option to support the devs, it's even mentioned in OP that it is open source project.

RIP playing while doing meth.

Edit: Oh fuck me, wrong thread, this shit was supposed to be in the esea one about PEDs.

Does this have the same smoothness as the game in full screen? I can't play TF2 in borderless because it feels like my refresh rate is cut in half. I have to play in full screen to actually feel 144hz instead of 60.

you could just get the free non-steam version and try it out. then it's up to you whether or not you support the developers by buying it on steam. (after reading some reviews, you might want to keep using the non-steam version anyway.)
my guess is that it won't be as smooth as actual fullscreen, but who knows!

there, at the bottom, is the download link to the installer.
(maybe you could add the free exe download link to the OP, @Bonafide)

see what was quoted earlier in this thread by me.

are you on 7? try disabling desktop composition by going with the classic or aero basic theme.

I'm on 8.1
