Weird heat blur effect/color

[kobalt_]

Hey guys,

 

It's been now 3-4 days i get this heat blur effect bug (see attached screenshots).

 

The only mod i'm using is Ka-50 HD cockpit textures (https://www.digitalcombatsimulator.com/en/files/602834/)

 

I didn't tweak any specific conf file those last days, so I have no clue at the moment.

 

Tried the "repair" function, didn't change anything (it downloaded a 32 Mb file though)

 

Did i downloaded something that broke the shader ? (for instance by connecting/downloading a mission on a public server)

Any idea on how to fix it ? (without reinstalling the game)

 

Thx in advance

Missions can not add anything to your DCS Installation, so that shouldn't be the problem.

If the repair didn't help, it seems to point towards the graphic card. What card are you using? Did you download a newer version of drivers?

My GC is a Nvidia Asus 750ti, with latest drivers installed.

My setup : i5 2500k stock clocking, 8Gb RAM, on a SSD. Playing with TrackIR 5, Saitek X52.

Using a custom monitors.lua for weeks now, without any problems (2 monitors configuration).

 

Thing is, i didn't make any change those last days in my DCS installation/settings, and the problem suddenly appeared a couple of days ago.

To tell you the whole story, i was playing in Ka-50, and the heat blur of my wingmen wasn't blue/white at first, but it looked like a dark shadow.

 

I was like "ok, whatever, problem will get solved at next PC reboot", but nah.

 

My CG is less than 1 year old, and never overclocked, and doesn't suffer any problem in my other applications / games.

 

How come this bug could pop up this way ? Without any setting changes ?

 

On the other hand, there have been many updates those last days...Could it be related ? Like an update among many others could have broken the shader ?

 

I played a lot Quake 3 (and many games with same engine) in the past, and it definitely looks like a broken shader code to me.

Uninstall the mod or repair and see if it's fixed?

GC overheating could change things the way U are describing. Have U checked that?

Check your monitor settings. I had a dual monitor config that was out of whack (I think it was the aspect ratio that was wrong, so it could happen with single monitor if this was wrong for you as well, I support) whose only noticeable effect was screwed up heat blur. similar to what you see behind the su-25. If nothing else just reset your resolution and let it recalc the aspect ratio, etc. I don't promise it will be what's causing it, but that worked for me.

Right, after further investigations (and a useless DCS reinstallation) I finally found the source of the problem : windowed mode.

 

xaoslaad you were pretty right with your post.

 

 

Here is why I play windowed mode :

Basically, I got 3 monitors plugged in : 2 "main" monitors in my 750Ti, plus a TV in HDMI, using my onboard Intel graphic controller. I only activate this TV/screen in Windows 7 display settings when I want to watch a movie, so most of the time it is disabled in Windows.

 

My two main monitors are a 29" 21/9 display (res 2560*1080) and a classic 1920*1080 24" display.

 

I made a custom lua monitor file to get this result (I mostly play BS2).

2560*1080 monitor is used as my primary and main display, while I'm rendering the ABRIS (resolution : 810*1080) on my second monitor.

 

It works fine, but only in full screen mode, with width settings 4480 (2560+1080). And I had about half of my second monitor unused only rendering a black picture.

 

With this setup, FPS wasn't that good (between 15 and 25 most of the time). But when I tried windowed mode, setting a resolution of 3370*1080 (2560+810 ABRIS as width), FPS got WAY better (improvement : from 50% to 100%, sometimes more).

 

If i try this exotic 3370*1080 resolution in fullscreen, it will work fine too, but not centered in my primary screen. So do you have a tip here to "force" fullscreen coordinates origin to 0,0 on my primary monitor ? If yes, then it will solve all my problems.

 

 

So, to make a long story short : I can live with this strange colored blur effect in windowed mode, I think getting such an improvement in FPS worths it.

 

 

Last thing (xaoslaad's post was right), I don't get any graphic bug in windowed mode when I use 3370*1080 resolution....

BUT (there's always a but) this way I can't move the window to make it fit with my screens....

That's why i set up 3370*1056 as resolution : to get the window title bar, and being able to move it...

 

Once again, things would be way easier if the game could start on my main monitor, and not centered across the 2 monitors...There must be an easy solution for that...

[kobalt_]

I forgot to mention : key shortcut "Windows key + direction key" does not work to move the DCS window from one screen to another...Whereas it works with all my other applications...

Can you share your lua, your monitor resolutions, what you want where, and symptoms? I had some 'fun' writing these not too long ago. Sometimes an extra pair of eyes goes a long way.

 

When I had a 1920x1080 main screen on the right and 1024x768 on the left this is what I used:

 

_ = function(p) return p; end;

name = _('Camera+MFCD Per Aircraft');

Description = 'Camera+MFCD Per Aircraft'

function default_setup()

Viewports =

{

Center =

{

x = 1025;

y = 0;

width = 1920;

height = 1080;

viewDx = 0;

viewDy = 0;

aspect = 16 / 9;

}

}

RIGHT_MFCD =

{

x = 0;

y = 0;

width = 1024;

height = 768;

aspect = 4 / 3

}

end

default_setup();

function reconfigure_for_unit(unit_type)

if unit_type == 'Ka-50' then

Viewports =

{

Center =

{

x = 1025;

y = 0;

width = 1920;

height = 1080;

viewDx = 0;

viewDy = 0;

aspect = 16 / 9;

}

}

LEFT_MFCD =

{

x = 0;

y = 0;

width = 1024;

height = 768;

aspect = 4 / 3

}

elseif unit_type == 'F-15C' then

Viewports =

{

Center =

{

x = 1025;

y = 0;

width = 1920;

height = 1080;

viewDx = 0;

viewDy = 0;

aspect = 16 / 9;

}

}

LEFT_MFCD =

{

x = 0;

y = 0;

width = 1024;

height = 768;

aspect = 4 / 3

}

elseif unit_type == 'Mi-8MT' then

Viewports =

{

Center =

{

x = 1025;

y = 0;

width = 1920;

height = 1080;

viewDx = 0;

viewDy = 0;

aspect = 16 / 9;

}

}

LEFT_MFCD = nil

else

default_setup()

end

end

　

Gui =

{

x = 1025;

y = 0;

width = 1920;

height = 1080;

}

UIMainView = Viewports.Center

Thanks for helping me out..

 

As I said in my previous post, when I play BS2 (my main module) what I want is :

- To get the main game display in my 29" screen (2560*1080)

- Displaying ABRIS on my second screen (1920*1080)

 

So my current DCS resolution is : 3370 (2560+ABRIS at 810) x 1080

 

Here is my current lua conf file :

 

 

_ = function(p) return p; end;

name = _('KA50');

Description = 'Abris on the right monitor, Shkval on ntoom left main monitor '

Viewports =

{

Center =

{

x = 0;

y = 0;

width = 2560;

height = 1080;

viewDx = 0;

viewDy = 0;

aspect = 2560/1080;

}

}

 

LEFT_MFCD =

{

x = 0;

y = 504;

width = 768;

height = 576;

}

 

RIGHT_MFCD =

{

x = 2560;

y = 0;

width = 810;

height = 1080;

}

 

UIMainView = GUI

 

 

Here is a capture of what i get with this lua conf :

 

 

So it's ok to me this way. I play with a TrackIR 5, Shkval is not annoying me.

 

 

Problems :

1. when the game starts, it starts centered across my 2 screens. Here's a quick photo showing this.

 

 

Possible fix : changing resolution to 4480 x 1080, to cover my 2 screens completely.

It works, but I can't Alt/tab to another app. And the game actually renders 4480 * 1080 pixels, even though about a third is black (the right part). Which reduces A LOT my FPS compared to 3370*1080.

 

 

What i want : to make the game auto starts with coordinates 0,0 at the top left corner of my main screen :

 

 

 

I think DCS windowed mode is sort of a fake full screen, or fullscreen with a border. Thats why it always starts centered even in windowed mode.

 

Thanks in advance

 

 

 

And current fix for heat blur problem : disabling it in options ... :music_whistling:

Still trying to solve this out...

 

Maybe this topic should be moved to another section dedicated to monitor configuration ?

 

 

Thx

had a heat blur bug when i changed my resolution for my multi monitor bezels...I only tweaked it a bit...DCS still ran but I had this bug...then I figure out it was my monitor res and ingame res being set different..

 

 

...So the first thing I will ask is do you have multi monitors and have you played with the resolution...check to make sure your resolution and DCS are the same because unlike other games, DCS will still run with bad setting sometimes, but you will get glitches like this.

 

 

 

edit...then I backtrack and see you do have multi monitors and have recently be playing with your settings...tells me you have some double checking to do....
