抗鋸齒  

現(xiàn)在任何卡運(yùn)行Crysis開抗鋸齒都是十分奢侈,游戲茂密的植被和各種shader都會(huì)貪婪的吃光你的顯存，即使你使用8800Ultra SLI也不可能在全特效開啟AA流暢的運(yùn)行，降低其他畫質(zhì)來開AA與其不如提高其他畫面設(shè)置，這樣對(duì)畫面的效果提升會(huì)更而顯著。不過Crysis還提供了邊緣AA（Edge AA，相當(dāng)于軟件AA，對(duì)物體的邊緣進(jìn)行模糊處理還緩解鋸齒，《幽靈行動(dòng)》最新作就是采用這種方式的AA）玩家還是可以嘗試用r_UseEdgeAA 2開啟Edge AA，雖然這種方式的AA效果不如MSAA，并且邊緣部分會(huì)變得模糊，但還是起到的AA作用，并且速度損失也不大。


在Windows XP和DX9平臺(tái)上設(shè)置接近DX10 Very High的畫面

前面我們已經(jīng)介紹過Crysis所支持的DX10特效，但實(shí)際上我們發(fā)現(xiàn)，許多所謂的DX10特效完全可以在DX9硬件上實(shí)現(xiàn)，針對(duì)這一點(diǎn)，我們發(fā)現(xiàn)了如何在DX9平臺(tái)上手動(dòng)打開Very High DX10特效的辦法，下面我們就一起來看一下如何讓DX9跟XP實(shí)現(xiàn)Vista下的DX10效果：

　　在autoexec.cfg里加入以下代碼讓在DX9環(huán)境實(shí)現(xiàn)接近DX10 Very High的畫面效果：
