Alt+Tabbing out of the game in the menu screen forces V-Sync off.

[Bitcoin Baron]

In Nvidia control panel, V-Sync is on, in game, V-Sync is on. But If I alt tab out, the GPU usage goes from 12% up to 90. And I can see by the steam FPS counter that the game is drawing like 400fps for a moment when i alt tab back into the game.

Are they aware of this bug and fixing it? It's not very nice that the game overrides my nvidia settings!

There is an additional setting in nVidia control panel.

3D Settings -> Manage 3D settings -> Background Application Max Frame Rate

[Bitcoin Baron]

There isnt such a setting on mine.

Perhaps you need to update your drivers? It was something nVidia added not too long ago in response to newer games doing this to folks.

[Bitcoin Baron]

But this aint a newer game, lol, its an older one. And the problem only exists on ETS2, and (I believe) only started happening when ETS2 upgraded to 1.41. Also at least for me, this happens on no other games. Therefore it seems reasonable to suppose that this isn't a driver issue (although granted I havent updated my drivers in about 4 months), but is an ETS2 issue?

Well, I know it's in my nVidia control panel and I'm fairly certain they didn't add it specifically for ETS2. ;)

Can confirm this.

You can set it globally for all games and even game specific.

So in that sense Photoshop 2020's core has not changed since 1988? ETS2 may be a older title but I would bet bottom dollar it is the most continually maintained and updated game on the market.

It happens with many DX11 titles that is why it is in the global settings of nVidia's control panel and has been for at least 5 driver version updates.
Look for "Background Application Frame Rate" set it to 30 or less.

[Bitcoin Baron]

I have set the background application rate, and this game is still flying up to apparently 724fps when minimized. I repeat setting the now available setting below what people have suggested is NOT fixing the problem.

The first alt+tab, it seemed to behave, but a second, moments later, it completely stopped and went back up to 100% GPU usage.

Did you hit apply to save the changes? Also, did you make it for the game in the Nvidia controll panel?
Because it works fine on my end.

Same issue, I have both this and ATS set restricted to 30fps and my global background FPS is set to 60, It ignores both and goes ahead and gets itself up to about 1000fps tabbed out. in ATS i even restricted the games framerate in the INI config to 72 so it wouldnt cook my room but it still goes ham when tabbed out. This is a game specific issue of it ignoring tab focus rules. The devs need to build in a limiter for tabbed out by default. lock it to 60 across the board natively, plenty of games already do this. Its why this game is the only one that I cant let sit in the background or it will probably start a real fire.

[kaki_gamet]

I had to set it in windowed mode, and finally that nVidia setting started to cap it at 30 FPS.
Give it a try, you may not dislike it (if it will works for you too of course).

Which they can not do as this is a bug with DX11.1.

G'day all. I know this is an old thread. But I believe I have found a fix to this problem if anyone is affected by it. Please follow the steps below as per how I fixed this for myself. Please be aware this may vary depending on where you have ETS2 installed:

Step 1 - Go to C:\Users\User\Documents\Euro Truck Simulator 2

Step 2 - Open the CFG file named "config.cfg" with either notepad or notepad++

Step 3 - find the line "uset t_limit_fps "0""
It should be one of the last entries in the file. In my case using notepad++ it is line 183.

Step 4 - change the "0" (zero) to whatever you would like the framerate cap to be. E.g. 60, 75, 90 etc,

That should set the maximum frame rate for ETS2 whether you are in game, or alt-tabbed.
Please let me know if you have any questions or feedback.

Thank you.

nice find but its probably better to learn how to limit your background fps in the videocard control panel as this will be a issue for every game minimized (losing the vsync and then running at max fps the gpu can handle)

It will only be an issue for games running on DX11.1 as the bug causing that is within the graphics API.
