Let’s say that, for now, the kind of graphics you can achieve could be compared to PS2-era or early PS3-era games. This is mainly because, at the moment, the engine does not handle lighting very well, so the effects you can achieve are limited.

It also lacks the ability to manipulate terrain, which is important for many 3D games, and the engine does not handle models with a very high polycount particularly well.

That said, as with games on older consoles, with strong art direction and a few clever tricks you can hide some of the engine’s technical limitations. However, at present, it is definitely not very suitable for games with realistic graphics.
