1. First off, 'ctrl+alt+u' to bring up user preferences. Under the 'System' settings make sure 'VBOs' is enabled.
( 시스템 설정으로 가서 VBOs를 체크한다!)
2. !! Important : In 'Object Data' tab, make sure 'Double Sided' is off.
( Double Sided를 해제한다.)
3. Stay in solid view. Do not use textures. Do not use the 'matcap' method. Do not use 'texture solid'
( solid 뷰 모드로만 작업할것!! 텍스쳐 등등은 느리다.. )
