Re: COD4 MP, GTX 480 super hitch.
Type into console...
Everytime you get the stutter you will see the fps drop around 100 for about 1ms every 3-5 seconds for about 2 mins. PB will then sleep untill the heartbeats start again.
the /pb_sleep command will increase the time it takes for pb to communicate with your pc. All the above console commands are perfectly legal and will improve lag/registration aalthough it will not cure the problem completly it will reduce how often it happens.
The stutters are caused by the way that pb scans the memory on 64bit OS.
