利用改變AA取樣位置+視覺暫留來獲得較佳的AA品質


而且效能下降不多

假如取樣位置改變3次能獲得更佳效果(前提是fps起碼有90)
2x 2x2T (4x) 2x3T (6x)

4x 4x2T (8x) 4x3T (12x)

6x 6x2T (12x) 6x3T (18x)


以下是連續影片下載展示TempAA的效果

更好玩的是居然有這種比法...
They are benching at 1024 x 768 at full IQ settings in farcry.
6800u is at 4xAA x 8xaf
9800xt is at 2xAA x 8xAF ( add 2xt with no performance hit=4XAA)
----------------------------------------------------------------------
Test 1
-----------MIN FPS-----MAX FPS--- AVG FPS
6800U ------21----------112---------40.7
9800XT------21----------101---------38.6
----------------------------------------------------------------------
Test 2
-----------MIN FPS-----MAX FPS--- AVG FPS
6800U ------22---------52---------33.6
9800XT------24---------44---------34.1
----------------------------------------------------------------------

最重要的是如何開啟呢?
開始=>執行=>regedit...然後找到
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\
裡面很多項.每項裡面都有0000
點到0000的頁面加入字串值TemporalAAMultiplier
OK後把數值改為2或3(每個0000都要)(2就是改變2次.3改變3次)
然後去改一下反鋸齒模式以便套用新設定

然後可以用D3D FSAA Viewer測是是否成功開啟(取樣位置會閃爍表示成功)

結論:
嗯...效果如何就交給大家補充吧
我想說的是...ATI的取樣位置真是神!!
NV不曉得會不會再度抄襲這取樣位置...
