i have played this game on a variety of computers including chromebooks and my desktop pc is the worst of them all, when i shoot it wont even hurt the other players, when i go to pick up a powerup it wont let me (even after some time of picking up any powerup) and over all am just a sitting duck. the specs go as follows: CPU: Intel Pentium D GPU: integrated into CPU (don't know what model) RAM: 2GB DDR2 BROWSER: Google Chrome i have never had this problem on a chrome book so i don't know what is going on. please let me know how to fix it, i am currently trying to get a nvidia geforce 8400 gs 1gb GPU to work in the desktop.
