MoW and RT very laggy performance

[thorik]

Hello everyone,
as the topic says, I'm having extremely bad performance during larger battles in MoW. I've tried lowering all the options to minimum, but it doesn't make much of a difference. My PC specs are:
geforce gtx260, AMD phenom II X3 720 - 2,8ghz 3core, 4GB memory.

So I guess it should run smooth, shouldn't it? As I can run Call of Duty modern warfare 2 for example on highest details smoothly...

Any suggestions?

Thank you very much.
