You could compare them to Quake 3's or UT99's graphics
Nexuiz certainly doesn't look as good as Half Life 2 or Doom 3 or FEAR, but it DOES look a whole lot better than Quake 3 or UT99. Nexuiz's models are comparable, maybe, but the textures are better and the engine is lightyears ahead because of the effects like realtime lighting and shadowing, HDR, and offsetmapping. I think the reason why the reviewer said that the graphics were comparable to Quake 3/Unreal 99 is because he wasn't playing the game at full settings - the screenshots in the review appear to have most of the effects off.
They should've reviewed Alien Arena and Tremulous too.
Anyway, besides being inaccurate about one aspect of the game, I think that this is a pretty good review. Much better than that Moddb one.
