NGS CBT main exe is DPI unaware. This is unbelievable in 2021 and result in a blurry mess on a 4k 200% HiDPI display. The game just output 1920x1080 and it's super hard to read any text from it. Forcing it to use "Application" scaling is not possible for a Windows Store App.
The game itself should already have correct scaling method since PSO2 itself works with HiDPI display without major issues just the config and setup is still messed up like it's from 10 years ago.
