This has nothing to do with EA. It is by design as stated on the Dev website. Some will not like it, some will. For me, the graphics fits the game setting brilliantly.

Q: The visuals of Valheim look kind of old, what is up with that?
A: We have chosen a stylized graphical look that blends low-resolution textures and sparse polygonal detail with modern materials, lighting and post effects. The visuals are inspired by the early days of 3D graphics, like the style seen in PS1 titles and old DOS-era 3D games (before hardware acceleration and texture filtering was a thing).
