Undocumented 9.7 feature: 4k UI scaling

Source: Reddit, dplummer

„For those tankers with a 4k monitor, you may have been angered at the lack of UI scaling. Although the game looks amazing, the UI is nearly unreadable. But no more! The 9.7 patch brings with it proper UI scaling. Probably from the new BigWorld engine version. Hooray!

The difference is huge. WG, kudos for that.
