Spring RTS Engine

Ok, when i go to play the game and try to scroll around the screen, it skips a little. like it moves for forward and then moves back a bit. its not just the screen but also the units that to that. its like as if i was playing a game online with lag but this also happens on local games. i updated my drivers and it worked fine the first time but then started doing it again. is anyone else experiencing this?

spec are:
AMD Athlon 64 X2 3800+ @ 2.1
Dual Geforce 6800GS's @ 460/1150
2GB(2 X 1GB sticks) dual channel RAM

other programs running in the background are winamp, aim, fraps, zonealarm and nvidia firewall, nvtemplogger, gigabyte easytune, software for my keyboard and mouse. I closed all the programs and still have this issue. I turned all of the settings down and turned down AA and AF. shadows are the only thing that I turned off and everything except sound and particles is turned up all the way. sound and particles are at about half. I am running in SLI but I tried without it and the issue still persists. any ideas?

Sorry, your computer is too fast for spring

It is probably caused by big difference framerate and the internal game update rate. Internally there are always 30 game updates/sec, and units positions get interpolated to make it look like there are more than 30 update/sec (For example when the graphics are rendered with 60 fps)

It's all just estimating, so it can happen that you see small discontinuancies (Is that a real word?) when the estimated position of the unit is replaced by the actual game position and the estimation begins again.

A lot of games have this btw, shooters for example, but then the camera movement is more diverse than when you're scrolling in spring

And let's not forget that you have a lot of background programs running that can also stall the system for a short time.

thanks/ you learn something everyday. i just thought it wierd becasue it was playig alright earlier, like two weeks ago andi've seen people with faster PC's running alright. then again, i always did find it wierd to get negative cpu usage
