Don't know much about Radeon graphic cards but ran "Far Cry" myself using Nvidea Geforce 4 4200 TI, AMD XP 2400, 512 DDR etc. Screen resolution 1280 x 1024 on a 17" TFT no problems at all. No expert here BUT seems graphic related problem to me. Are your graphic card drivers up to date ? Have you checked the game website to see if there is a patch available ? Keep trying, this is a great game. regards.
