I used to play this game with no issues whatsoever on my old PC and now, with Win 7 64-bit, NVidia GeForce GTX 750 Ti, Quad Core Q6600 processor, and 4 GB RAM, latest version of Firefox installed 49.0.2, latest versions of Java and Flash player, C++ from 2015, directX 11 and 6 mb/s cable connection I can't play minidayz normally, it's soooo laggy and it kind of feels that FPS doesn't go over 10. It's so slow and unplayable on single and multiplayer all the same. What's the problem?
