Does it have now , the thing that any today engine MUST HAVE , ESSENTIAL : water shader doing real mirror , or that we can tweak to have a good effect with less performanace impact like OPtions in AAA games?
Lol, I couldn't disagree more... a single (water) shader doesn't suddenly make your game on par with AAA game quality.. If there's one thing that more or less does, it's the lighting engine/shader/part of the engine... off course, you'll need high quality art, models, level design and coding as well, but those are terribly obvious,
