Question: Why am I seeing 'corrupt graphics' even with updated ATI graphics drivers?

Answer: There is a known issue in GTA IV if you have your 'MipMap' detail setting in Catalyst Control Center set to any setting other than the max 'Quality' setting.

Please open the Catalyst Control Center and make sure this set fully to 'Quality' and then re-launch GTA IV PC to see if the problem is resolved.

Please always make sure to use the most current driver versions, and whenever possible, remove the older drivers and reboot before installing new ones.
