這版的readme有提到FastWrite的問題..

----------------------------------------------------------------------------
5- I have received various E-Mails asking about FastWrites, there is only one

The Radeon cards do support FastWrites and they will work with it on
(on some machines), but it is not recommended, there is NO SPEED gain
when using FW, and this option will affect your PC's stability a LOT.
