what you having is call screen-lag this can be from too many item running and screen size 800x600 is to much for you lower the setting down this help screen-lag move faster per-frame rate (Fps)

how much ram is free to use for the game best tip reboot your system to free some ram up, and as katana*GFR* (only user name) disable some of them or close them down (stop running)

you may have a lot of ram but how much is it free up for the game to use best restart the system to free it up, having a lot of programs running and you may have close them out but their data is still in the ram by restarting your system you clean that data out and free some of it up to use.
