"Let's say that we're in Devil's Catacomb and i want my client to be optimized, i enabled this option and all bosses/mobs become a dog, now everything is perfect, no lag anymore, WTF, we did metin2 great again, we're genius"
Yeah, it's probably the best optimization I've ever seen. ?
Speaking of effects, do you have any idea how to fix the effects processing so that you don't get a black screen when you minimize and maximize the client?
All decisions in release which consisted in not stopping rendering of effects at folding seems to me any nonsense.
