I said performance of Unity is better because an Esenthel user, a former Unity user did engine comparisons with exactly the same level designs in this year. But in spite of the slower fps he moved to Esenthel, because had a lot of trouble with Unity (unsolved engine bugs etc.)

And Esenthel seems to be faster than Neoaxis due to my experiences - but did not make exact measurements...

For making lot of small (commercial) projects 3DGS A8 is much better because in Lite-C scripting can be done very effectively.

But Esenthel offers a lot of good things: no limited graphics features if you use free or cheaper editions (only no access to some source codes what you maybe don't need at all), the all-in-one editor, and its good terrain handling, which is important for me. By the way I don't really need an editor because I'm having my own one but no time to complete it...

So I'm testing it beside using 3DGS as a possible alternative tool, but its usage is really different of 3dgs.
