Hey, Ive already read previous threads about this so dont even suggest my computer isnt good enough to run CC.
Build 22 on my crappy computer with only 512 mb of RAM was able to run CC MUCH faster than my 3gb computer. I've also realised that there is a slomo thingy too, which I have turned off, this isnt the problem. The framerate is just horrible. Any suggestions on how to fix this? The good computer runs on vista btw.

It even has a choppy framerate in the friggin menu!

Running any extra programs?
Using Windows 7 Beta, perhaps? That caused problems with my CCB22 install...

Try to be more specific.

Nope Im not running The windows 7 beta Im running on Vista home premium and the only backround programs Im running are Norton protection centre, MSN, windows defender and Steam. Ive tried Running it with all these programs turn off but it doesnt improve the framerate, It barely uses any of my CPU but still runs jerky. I am able to play other 2d and 3d games completely smooth. Just not CC

this just means your CPU is one of the many that hates CC. id suggest upgrading, but as that is obviously not an option, go to base.rte/settings.ini, open it up, and find the deltatime line.
up this variable by .005 increments untill happy. also, play with the speed of the sim with the 1 and 2 keys on your keyboard.
to keep the rate good, turn slowmo ON.
