XBOX360的實體輸出解析度不滿720p
看來還真的是小畫面scaling到720p....
http://www.beyond3d.com/forum/showt...?t=25474&page=8 http://www.beyond3d.com/forum/showp...9&postcount=185 1024 * 600 * 4 * 2 * 2x AA = 9.375 Mbytes ---- http://www.beyond3d.com/forum/showp...8&postcount=202 根據這篇的結論，狀況很明顯： 為了迴避手動tiling(把frame buffer拆開)，於是PGR3使用較低的解析度，然後靠後面的 scaler縮放到720p。 看先前B3D的文章，ATI提到了1280x720需要兩個tile、1920x1080需要4個tile、開AA的話還 要再增加；當初就覺得，既然有tile，分次搬動顯然需要增加時間，怎麼可能AA會不損耗效 能....不過至少ATI有提到tile mode的話，那大概應該會是個"自動功能"。 現在PGR3主動迴避掉tile mode，看來這玩意兒和PS2的GS支援1080i的方法一樣，都需要 developer手動重組記憶體、以及精密的timing控制；但是Unified Shader這類自動的load balance又很不適合這種timing控制....於是大概只能全部當PS，VS拿3core PPC，以下類 推.... 看來麻煩的事情還在後頭。 |

哇勒,艾曼紐名言:怎麼會?
既然這樣那當初為啥不把EDRAM用大一點? 不之能否手動關閉AA來達成真正720P? |

和PS2的1080i一樣，靠時差管理分配來支援高解析度吧。 ATI先前也這樣說，只是看起來不是自動就能做到，而是要手動仔細分配。 |

所以搶第一版的就是自願花大錢當白老鼠...=.=
雖然現在一些賣場都有bundle HDTV... 但是我還是等等好了...

XBOX 360的當機問題找出,電源供應氣過熱~orz 只要把XBOX 360離地讓空氣流通或拆機殼就行了,不會吧!乾脆買XBOX 360送隻螺絲起子比較快~orz |
