2x- Radeon HD 6870 (stock clock)
AMD Catalyst Driver Version, and Driver History
12.7b and 12.8
Windows 8 Pro x64 RTM
Uninstalled catalyst 12.7b, installed 12.8 and got very bad stuttering while playing GTA IV EFLC rendering it unplayable. I've switched back and forth between 12.7b and 12.8 and I have confirmed the issue does not exist when using 12.7b and is occuring in 12.8.
Applications and Games
Grand Theft Auto IV: Episodes from Liberty City (Steam version, latest patch)
AMD FX 8150 OC to 4.2Ghz
My OC utility does not work in Windows 8 but I can guarentee you it is stable. If you really need further details I can go into my BIOS and get my settings but I really don't want to as I'm sure this is not the issue.
