Hi, I have some issue. I have "little" bad computer (Intel Pentium J2900 4x2.41GHz, 4GB of RAM, nVidia GeForce GT800A, Windows 8.1). And my problem: if I stand on place (starting tram or on place normal), game is OK, but if I start way by tram, game is lagging (fps dropping from ~20-30fps to 1 fps once a few seconds).
Thanks for help
