Installed bf1942 ... patched it all up on my mates machine

When i connect to a game... im always walking in slow-motion!!!

I managed to jump in the back of a plane as the gunner... & i played at the correct speed!... but if i just walk about or get in a vehicle its always dead slow... not jerky or anything... just run really really slow...

I havent a clue whats wrong!

The PC spec is:

AMD 1.2
256 RAM
GeF-2 MX Gfx
Dx 8.1 with hotfixes

Anybody have any idea wft is going on??! ... its doing my box in!
