After the upgrading the ROM to 1.00.15, I found that my Acer n300 no longer showing text in ClearType. In fact, the text looks uglier than before.
In version 1.00.08, ClearType is enable. So that the screen looks better to customers in store. In version 1.00.15, ClearType is disable. It can then claims the performance has boost up after upgrade.
Besides me, there is another guy who found out that the ClearType was disabled on new OS. Some one has the solution to re-enable ClearType. This one is cool~~
Method 1. Search "NoClearType" in registry and set its value to "0". ClearType options is available under Settings > System > Screen.
