Ragnarok on 4k?

[nexuspolaris]

I'm trying to run on my 4k display and all text and icons looks too small.
Full screen on 4 k resolution craches the game with d3d error.
Any help?

Use 1600x900 or less. Even classic fulhd is too much for this game.

Ragnarok uses DirectX 7, which only supports resolutions up to 2048x1536. Anything above that won't allow you to launch the game.
