Chrome used to be the least memory intensive but Firefox became better a while ago.
I wonder because one of my cities i play on my second comp; an older comp. 2007 iir, running XP.
i cant say i would blame elvenar if they removed it. Consolidated there resources.You are an exception with your legacy operating system. Windows won't remove flash on you since you no longer get updates, and the browser version you use will not update for your specs, so you should be safe there as well. As for what the Elvenar team decides to do, that is the question. They may remove their flash codebase, because no one (besides you legacy users) would be able to use the flash codebase anyway.
