Ultimate Spiderman 15fps argggg!!

Hi guys,

I've just bought ultimate spiderman...installed it and played it. When I first start playing (first 10 seconds) the graphics are smooooth...but after that they start to jitter, and i must be getting around 15fps at the very most!

I've looked at the min requirements for the game, and my computer is well over those...even with all the graphics settings at there lowest i get jittering...

My graphics card is ATI Mobility Radeon x700 128mb....I play Need for speed underground 2 at full resolution and 1024x768 and it runs flawlessly...so why does my comp have probs with the cell shaded ultimate spiderman?

If anyone could point me in the right direction I'd really appreciate it...thanks in advance

 

I would lower some of the graph specs and see if this clears up a bit

 

i have already tried that (as stated in original post )...any ideas guys?

 

maybe I should read more the post instead of skimming lol, my fault.

let me digg somthing up to see if I can't get some more info with troubleshooting.

 

i've just updated my graphics drivers to non-OEM ones and its a lot better, still not perfect...any suggestions would be great
