so... what is the idea asking about the source code and posting videos of your owns projects?, there was people trying to say like our project isn't so good(jealous people who even tried to blackmail us trying to force us release our project, and when failed tried to hack us...), but I will make everyone understand why they are wrong saying things like that, first, if it is so easy make MU run at high FPS and keep it stable(it isn't the same just one character and few monsters, than an entire map full of bones or a map with 300 characters with full equipment and pets), Webzen would already have done it long time ago, but they didn't do it because it is something really hard to do, we're not talking about migrate the Graphic API, because of course we can get this performance with OpenGL, Vulkan, DirectX 12, Metal, any Graphic API, that isn't what cause slowdown, the entire game cause slowdown, it is extremelly bad coded, and don't need any source to say this, anyone who has at least a little of knowledge of ASM x86 can know this, just disabling FPS limit, modifying a few lines of code won't improve performance at all, Webzen client is just an obsolete client which will never be able to do better except if you entirely rework the game from the ground(this is what we did, talking about Elion), and even if rework it from the ground there is a huge chance you won't improve it at all or just a little(that is the reason why Webzen didn't do it yet), I had to implement many of my theories in the code that made it work like I wanted, very well optimized and with native anti-hack, if do this is so easy, then go ahead and do yourself, there is nothing preventing you from do it.
