Full screen kills the game dead.

Got a problem? Let us know!

Full screen kills the game dead.

Postby YeGoblynQueenne on Thu Jun 12, 2014 1:23 pm

Started the game, then switched to full-screen, and it started dying in agony. The screen flickers constantly between a blank screen and fleeting glimpses of my desktop, so I don't even have enough time to kill the process. I have to restart to be able to do anything on the computer. It looks like it's locked in a vicious struggle for control of the resolution with windows, 'cause I can see the cursor changing sizes every half a second or so- but it never settles.

That's on Windows 8.1 with Intel integrated graphics.

I've uninstalled and reinstalled three times, also ran a registrly cleaner, but every time I start the game it tries to go to full screen and keeps failing like that.

I'm looking for an .ini file or maybe a registry key I might have overlooked. It must be storing that fullscreen=1 (or sth) value somewhere.

Haven't played the game almost at all and spent way too much time trying to find the setting. A bit sad now :(

Whoa, okay.

Step 1: Make sure your graphics drivers are up to date. It sounds like the game is having a hard time trying to render to texture, which is usually a driver support problem.

Step 2: Point your registry at HKCU\Software\QCF Design\Desktop Dungeons and change the fullscreen value there to 0.

Hi and thanks. I'll have to try that tomorrow (the problem is on my work machine)(promise not to tell my boss).

Just to clarify: I played the tutorial with the game in windowed mode up to the point where you first level up and it was playing OK. That was when I tried to go full screen and it all went badly. That's why I think it's the full screen mode that did it. Apologies this wasn't clear in my fist post above.

Would changing to full screen make a difference in my card's ability to render to texture?

The game isn't doing any rendering to texture until you exit the standard 1x windowed mode, so yes, that's probably where the issue lies.

Alright, that's fixed- I can now start in windowed mode and the game is
playable:

Code: Select all
> ls 'HKCU:\Software\QCF Design\'


    Hive: HKEY_CURRENT_USER\Software\QCF Design


Name                           Property
----                           --------
DesktopDungeons                Screenmanager Resolution Width_h182942802    : 800
                               Screenmanager Resolution Height_h2627697771  : 600
                               Screenmanager Is Fullscreen mode_h3981298716 : 0


I think wot happened is that the QCF Design registry key got corrupted one of
the times I restarted windows to get out of the vicious circle of blinking.
This is what the key looked like this morning, before I deleted it and
reinstalled the game (to get the key to be created correctly):

Code: Select all
[HKEY_CURRENT_USER\Software\QCF Design\DesktopDungeons]
"Screenmanager Resolution Width_h182942802"=dword:00000780
"Screenmanager Resolution Height_h2627697771"=dword:00000438
"Screenmanager Is Fullscreen mode_h3981298716"=dword:00000001
"fullscreen_h1476830426"=dword:00000001
"resMultiplier_h3046660074"=hex(4):00,00,00,00,00,00,00,00


One of those values was marked as "invalid" in regedit. Sorry, that didn't get
copied in the dump above, so I'm not sure which one it was- I think one of the
fullscreen ones?

Anyway, carry on- it was just windows being, well, windows :)

Oh, btw- my graphics drivers are up to date. Still can't start in fullscreen :0

I have both an onboard Intel HD Graphics 4600 and a dedicated Nvidia GeForce GTX 765M. I've started the game with both and neither can start it in fullscreen. I've had this problem with another game (Shadowrun Returns). I do have the latest (stable) driver from Nvidia. So not sure what's the problem here but it's probably something specific to my setup- and I don't really mind playing in windowed mode so.

Looking at those registry keys, it seems like your fullscreen resolution is 780x438... It looks like that's where the problem is coming from: The game is trying to set a resolution larger than 800x600 and it's not getting that back from your OS. You're definitely right about it not being the graphics drivers, I have a very similar setup on my laptop and the game runs without any problems.

Is your screen really that small? Does that mean that when you play in windowed mode, you can't see all of the game? What pixel resolution is your screen actually at in Windows and do you have any idea why the screen might be reported as that size instead?

Those registry values are probably in hex, and if they are, 0x780 x 0x438 is 1920 x 1080.

Derp. That would make sense...

Although in that case I have no idea what's causing the weirdness.

Sorry, missed this. Yeah, I noticed those values too and also misread them as decimal, thanks thegabbert :)

This is my laptop model:

http://www.clevo.com/en/products/prodin ... ductid=474, currently witha core i5-4200M. It's connected to two BenQ 24" LED monitors. When I got this issue the game was trying to go fullscreen on one of the BENQs, my main monitor (which is probably what it should be doing).

Btw, don't know if I made that clear eralier but although I can now play the game OK on 8.1, I still haven't been able to go fullscreen on that OS version- I keep getting that eternal flickering/ cursor scaling. I've done fullscreen without problem on my Win 7 home laptop (with intel onboard graphics only). Can this be an 8.1 thing?
