Can anybody tell me what the ATI Radeon cards are like with Race On / GTR Evolution, I've read about stuttering problems. I currently have an Nvidia 8800GTS 320Mb so limited to low AA settings but have to use nHancer to get them to work anyway. I want to upgrade and seeing as the GTX275's and GTX285's are being discontinued and difficult to get I am thinking about a Radeon 5850. So my questions are: 1. Are there any stuttering issues 2. Never used ATI before so can I set all the settings in its Control Panel for use in game (AA, AF etc), unlike my nvidia where i needed a third party program (nHancer) Thanks.
