I did two 1v1 PvP fights at the same spot (the same ring at San Tu 2) within a couple of days. First in EDH, second in EDO, however very similar for this kind of 'stress test'...
Conclusion for the scenario of a pvp fight, most likely a very demanding scenario: FPS in EDO are 50 % of those in EDH...
Why?
Or is it to be considered an improvement - as announced along with one/some of the several updates since EDO release - to have around 55 fps in EDO instead of... 20? ^^
