jME, Xith, Java3D comparision for Quake3 level

One of the jME developer blog has an interesting head-to-head comparision for jME, Java3D and Xith rendering the same Quake3 map. See few differences on sky color and here and there “shadow” differences on a ground.

Other than that, Xith were slowest of three. fps were taken with FRAPS tool, I dont know how it works but I consider it gives about the correct results.

It would be interesting to run the tests again with the patches that have been made (for Xith) following that.

EDIT: And I want to point out this benchmark tests static geometry only : where jME (and Java3D?) uses display lists and yet Xith3D doesn’t. Maybe for dynamic geometry the situation is inversed (Xith uses VBOs).
