guys he is also getting a error maybe its the game problem! that causing lags! if it was only uer specs u would not get this error. errors dont came up with low specs!
The RESC10 error is a videomem error. There are a few ways to drop features to lower the video memory usage, but considering the rest of the system, I don't think it'll be very playable anyway. If lowering all the details and AA on the game doesn't help, try this:
Go to your NVidia control panel and disable GPU PhysX, set rendered frames to "0", and set to single monitor compatibility mode. Seems to have helped for others but like I said, between the OPs system memory, CPU, and GPU combination, it may not be very playable anyway.
