I've been jumping thru hoops with Codmasters VIA email and doing all sorts of dog and pony tricks....
It does the same thing with or without overclock. It does the same thing at uber low settings, it does the same thing at mid settings It does the same thing on high settings. It does the same thing with my router removed (direct from modem). It does the same thing with a brand new modem. It does the same thing with different AV (used Avast on old system, use NOD32 on new). It does the same thing with my firewall disabled. It does the same thing regardless of whatever campatibility mode is tried. It does the same thing with all startup services disabled.
It's not my hardware, I run programs far heavier than Dirt3. Its not my mobo/video/sound/network/input drivers, they are all up to WHQL standards (no hacked or beta drivers).
It did the same thing on a Q9550.
It does not do this without GFWL running. Its not the PC, it's GFWL. PERIOD
