Custom DPI scaling , unsupported?

[BATTERYMAN [ SUPERCHARGED ]]

First thing, i need custom scaling so i don't go cross-eyed because the font in widows are so small
Second..
So, unless i force the launcher and the game to override the application DPI behaviour , the game have issues scaling, almost as its in 50% scaling mode, which will result in blurry text and alot of shimmering on the 3d graphic , like cars and fixtures.
I notice also the launcher override the DPI scaling on Automation, if not both are set to same DPI behavior.
I know that the launcher text will be render outside of its boundary when using custom monitor scaling, but i will rather have that smal issue than blurry gameplay .

I play at 250/300% scaling (depending on circumstances) set at system level. The launcher is messed up in all sorts of tiny ways but that's minor stuff. The issues you encountered seem more serious.

I remember, I think during the previous major non-openbeta releases I used to have the same problem where instead of being scaled smoothly, everything was just blown up and pixelated until I changed from fullscreen mode into windowed and back into fullscreen. Don't have that issue anymore though.

Are you using Windows' built-in Settings app -> System -> Display -> Scale and Layout setting for scaling, or something else? Also do you have any compatibility options enabled for the game itself, in application properties? What are you using to override the DPI? I personally have no app-specific overrides and, as I said, don't see any weird shimmering or nothing.

My monitor is 1440p if someone wonder.

So the setting i use to override manually is Program DPI and override high DPI scaling by application.
set on Automation launcher and the game executable.
I'm using the windows build in custom scaling of 150%, and the reason are, that for some reason , the normal scaling iteration seems more incompatible overall for my programs.

The shimmering is because the 3d is rendered in lower than native resolution.
Even alt+enter seems to not fix the issue. resulting in slight blurry scale up

However once i run override, then the game launch at proper window size, and not 50%, and the fullscreen seems to render in proper base resolution, where the text is clear and the 3d looks clean, "no-aliasing"

I'll take a look tomorrow. Should be easy enough to investigate.

I don't seam to have any issues with the launcher, at a windows DPI scale of 150%.

But I do see batteryman's issues with the game itself. I can see that it is creating a back buffer of 1708x960 rather than 2560x1440. Hence the shimmering text.

I will raise a ticket with Epic to see if this is expected behaviour, as for UI there is a seperate UI Scaling/DPI system. So it does seam odd that it is resizing the back buffer.

Actually found a fix, is a bit of a bizarrely worded feature (the tooltip that describes it isn't great).

I'll enable this setting for the next update, but you can turn it on yourself by editing the following.

Go to the Automation install folder in Steam (Right click Properties on Automation in Steam, Local Files, Browse Local Files)

Go to UE421\AutomationGame\Config

Open DefaultEngine.ini

Find the section: [/script/engine.userinterfacesettings]
Add:

bAllowHighDPIInGameMode=True

As the last item (After UIScaleCurve)

That fixed it for me.

Regarding the launcher, for me (300% scaling currently) it looks like this (default size at launch):

And if I manually try to resize it, the content starts getting cut off instantly, starting at the top-left corner:

Great to hear about the in-game fix though! I understand debugging, fixing and testing this kind of stuff can be a pain :D
