大哥,你愛說笑了,後面都對,但音效處理用GPU來做,太殺雞用牛刀,還增加整機耗電。
在1997以前,音效卡百家爭鳴,有各種專門DSP晶片再處理音效,但是AC97規格出來後,CPU漸漸夠力,就把所有音效處理的計算收回到CPU處理計算,然後這些DSP晶片都下台一鞠躬,十年前CPU就可以輕鬆處理,現在當然是小蛋糕一塊,何必為了這點小運算量,啟動耗電怪獸GPU?

技術上絕對可行, 特別是再玩遊戲的時候

2004 年就提出的構想, 並不是說笑, 天曉的directcompute 會不會真的把音效運算丟給 GPU?

而且, 不是全部的 GPU 都是耗電怪獸, 低階卡就足以處理這些音效, 但是低階卡會耗電嗎?

說笑? 我不覺得

Cain was the first man ever to strike down another... and when the Lord came to him and said ‘What have you done!?’, Cain could not hide his crime. For the voice of his brother’s blood cried out from the very ground

The world has been your battlefield, everywhere you go. The blood of brothers and sons screams out against you. Perhaps you cannot yet hear it, because the soil is not your own, but you will... you will
