Graphical Twitch when moving in games

[ddunn]

Some games(wii) run perfect for me on max settings except the occasional graphic twitch especially when im moving. It's a minor issue & it doesn't affect the FPS, but it would be cool to get it to run perfectly smooth, if possible. Any suggestions? Do i need better specs? Lower my settings? If anyone could help, I would be eternally grateful. My specs:
Windows 8.1
intel core i7 4770k CPU @ 3.50 GHz
8 GB DDR3 RAM
2 TB 7200 rpm Hard Drive, 120 GB Solid State Drive
Radeon R9 270X 2GB graphics


Thanks!
