Cyber Diner

I found that if you took in-game screenshot using the F10 key or what you had assigned to it then it was what ever you had your screen size in the video settings @ 2560 x 1440 and .jpg format. Average file size: 650kb

But if you took a screen shot via the in-game Photo app key then it was saved @ 3840 x 2160 and .png format. Average file size: 10,500kb

And although my game was running from my D: drive those large photos found in:
C:\Users\xxxxxxx\Documents\The Crew 2\Screenshots\Pic_20180601_001056_3840x2160.png

Could find no way to reduce the size or file type in the Photo app settings.

There was no scalingoption like in TC1 so far. I guess that will come in the final version. I will take a look at the saved pics how big they are when i'm at home tonight.
