Game won't run in "true" fullscreen

[Pohititel]

When I switch Fullscreen on/off it only adds small border on top of the screen. So basically instead of fullscreen game runs in borderless windowed all the time. Also vsync doesn't work at all which gives me a horrible tearing. Changing resolution with fullscreen enabled leads to picture stretching.

What I've already tried:

- Any combinations of frame limit with different fullscreen options and resolutions
- Starting game holding Shift for a settings screen
- Messing around in Nvidia control panel with Vsync and performance options
- Changing desktop size and position in Nvidia CP
- Changing monitor refresh rate in windows settings
- Updating Nvidia drivers to latest

Yes, the game runs in borderless windowed mode.

We ran in true full screen for a couple of builds and it was horrible, just horrible, so many people complaining on the forum.

"The game starts black" - because their monitor didn't support our initial 1280x720 resolution
"The resolution switch takes for ever" - to be fair, it does in true full screen.

So we opted for borderless window mode for mostly happy customers.

You might be able to re enable it using command line options listed under the "Unity Standalone Player command line arguments" section here http://docs.unity3d.com/Manual/CommandLineArguments.html

What's strange is you are the first person to report that vsync doesn't work, I wonder what is special/different about your setup. Beyond what you have already tried, I'm not sure. Sorry :-(

Wow, thanks for a fast reply!

Tried with "-screen-fullscreen 1" and it starts in borderless fullscreen. Is it the right command? I double checked if those options work at all and "-screen-fullscreen 0" started the game in windowed with small border on top of the screen.

The difference is I have windows Aero theme disabled which leads to tearing in desktop applications, youtube videos and such. Windows doesn't have any other way to enable vsync on desktop. With Aero my videocard driver often crashes.

This thread is incredibly old, but did you ever solve the Vsync problem? This game has been on my wishlist for awhile, but upon finding out that it was built in Unity (and knowing that Unity games almost always have Vsync problems; ive avoided it so far as most games without working Vsync are unplayable for me. I have a severe framerate and tearing sensitivity that gives migraines and nausea.)

Earlier today i found a workaround for Vsync issues in another Unity game that only had borderless windowed mode (Sublevel Zero) by forcing Directx 9 mode for Unity. It may work to solve your Vsync problems as well, but I have no idea if it will cause any other issues.

Instructions:
1: Right click on the game in your Steam Library.
2: Open the Properties menu item.
3: On the General tab, click the "SET LAUNCH OPTIONS" button.
4: Inside the launch options box type: "-force-d3d9" (Without the quotes.)

If possible, please let me know if your Vsync issue was solved by the developer with various updates, or if this solves it. Id like to know if this workaround fixes Vsync in other Unity games as well.

I had to enable windows Aero theme everytime when I wanted to play an that was the only way to play with vsync.
No updates ever touched this problem.
Thanks for sharing the info, but it didn't work for me.
Steam asked if I wanted to play dx9 version and it still started in borderless fullscreen without vsync
So if you don't have troubles with windows Aero, enable it and enjoy. The game is awesome.

A upcoming unity adds a command line argument for true full screen. Woot! So people will be able to optionally enable it. Will try and remember to post on the thread when the build goes live.

Ive tried enabling Aero for various games in which vsync does not work (despite the games having vsync options) but its -never- resolved any of my problems. Theres a small possibility that due to heavy windows configuration, ive maybe disabled or broken some aspect related to Aero / DWM though. No easy way of testing that.

DanT: What version of Unity do you expect that feature to be implemented in, and with what command-line argument? I know your game would need to built with the new engine in order to support the commands, but id be curious about testing a forced fullscreen mode with other Unity games that only offer borderless windowed modes to see if that'd be a solution. Sublevel Zero just released a new beta build on Unity 5 (not sure which version though) that i could test with.

Are you talking about "-windowed-mode exclusive" I was looking through the Unity 5.3.4 patch notes and saw that they had added that. Wasnt certain if it was the one you were talking about however.

I tossed that argument into the Steam command line for Sublevel Zero and it also seemed to solve my vsync problem. Tabbing out of the game resulted in not being able to tab back in again though. (but using alt-enter to pull the game into windowed mode allowed to escape the fullscreen and also allowed alt-entering back in which re-enabled fullscreen and vsync). Might be something to keep in mind.

Yes, that's it. I have heard it's only part of the solution though, as you say. Other games have had to write custom plugins to steal input and stop people ALT tabbing...

[DanT]

That update is out, you can now try the flag.

[[yep]Thmyris]

So there is no way to play this game exclusive fullscreen right now? Even with the problems it brings with alt-tabbing?

Unity doesn't have exclusive full screen https://twitter.com/sehurlburt/status/860972530210713600 sorry :-(
