Anyone got a Dual Core AMD cpu and running this? (or rd2 for that matter) I'm having very stuttery game play and the same thing is happening in menus too.
So far I've found advice to turn on the lock frame rate option on the advanced gfx settings, which has slowed the menu screens down to normal, but I don't see why I shoul dhave to in effect slow down my gfx card.
I've also been advised to install the AMD dual core cpu driver which I've just done. This has helped but it's still not as it should be. The only other ting which was suggested was to turn off one of the cores for the game and it will run ok. Anyone know how to do this?

Hi, I was havinging similar problems on my dual core system with another racing game (Rfactor) and also EQ2 as well as a few other games. After checking the web I found the following three things helped resolve most of my problems and for what it's worth my x2 4400 runs this game fine without having to run it off one core or change any of the game settings.
1). Install the latest AMD drivers from
http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_871_9706,00.html
If your running XP non 64bit version then it's version 1.2.2.2 you need to download. I know you said you already did this, but it's worth double checking you have the latest version.
2). Install a Microsoft hotfix (kb896256 only for SP2) and apply the registry changes as described in this article:
http://support.microsoft.com/Default.aspx?id=896256
The patch isn't available for download directly from microsoft unless you get in touch with them, or you can download it from my site here:
http://www.sparkyweb.com/WindowsXP-KB896256-v3-x86-ENU.exe
3). check your boot.ini and ensure that the switch /usepmtimer is on the end your [operating system] line, for example mine is:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer
make sure the only change you make is to add the switch on the end though.
Alternativly if thats all bit much, just run it off one core, to do this start the game and get to the main menu screen, alt+tab to your desktop and launch taskmanger, click on the processes tab, find the RD3.exe process (you can click on 'image name' to filter the processes alphabetically), right click on RD3.exe and select 'Set Affinity' and then untick one of the CPU's, usually I untick CPU 1.
Please note you do this all at your own risk

I can only tell you that I found that after doing these three things I've had a lot less trouble with my dual core in general.
