About Unity vs Esenthel here in this thread
Well, if the test is correct, it seems that there is a big diffrence in favour of Esenthel
In Unity free version, shadows are disabled
It is well known that shadows eat a lot of PC cycles
You can use Unity pro for a limited period of time
Did anybody carry out a comparison test Unity Pro > Leadwerks or esenthel using the same scene ?
Unfortunatley my Unity pro trial version has expired

PS

I got the direct opposite results, Unity was the fastest engine I tried out
