one thing...
why is reducing the res to 640x480 helping to reduce the FPS issue ?

the best thing to keep in mind is not to RESIZE the original window and let it in its original size ! that way any problems relating to your FPS will almost likely not be as big as it was !

now, think guys/girls !
LAG = the time it takes to the data to reach his destination and coming back to you with the answer... some likes to call that PING which is exactly it !

FPS = Frames Per Seconds, which means images per second that your computer is passing into ! do not put both in the same bag as they are very different.

for the LAG you cannot do anything about it ! it always depends on things we don't have access to ! that's why there is LAG in ALL games including those you buy at the store !

FPS is the only thing we can do something about it !
FPS ISSUEs are caused by your VIDEO CARD not being able to follow the graphics bandwidth !
example:
your CPU (processor) is able to do a lot of operations but your video card isn't all that good and your ram is somehow low. then the CPU rushes trying to bring the info to you but it all jam and the CPU is reduce to giving you the info you need in a lot more time then he normally would do !

what does it do...
you got IMAGES SKIPPING which is FPS ISSUEs !

to reduce those, you try to make just that application running that way you're sure that your computer ressources are all at this program discretion !

also, know that this game requires a 500mhz and more to actually play well in this game !
be sure to meet this requirement or you're gonna have a not so playable game on your end !
