事實上XONAR的GX2.0的EAX5模擬技術不但能讓EAX5的遊戲啟用EAX HD選項, 國外的評測也聽不出差異, 甚至還有認為比XFI效果還好

Battlefield 2

BF2 is an EAX 3.0 enabled game which sure enough, once the GX and game settings were chosen in the Xonar Audio Center, I could set the Audio functions to ‘Creative X-FI’(which gave me a giggle) and High settings (ultra is also available through config settings):


The EAX effects were clear and no crackling and popping could be heard which has been reported occasionally with Creative’s own X-FI based cards. Positional audio was sublime and no doubt would give the players a competitive edge in this game with a 7.1 card. I had played this game previously with an extreme music X-FI card and honestly cannot tell the difference between the two cards audio qualities.

這個2008/5/14刊出的14頁評測大作也有很詳細的分析

"As I already noted, the latest driver from ASUS makes it possible to enable OpenAL in Quake 4..... Loading a few saves from different levels I was surprised to hear the Xonar D2 being quite competitive against the SoundBlaster X-Fi again!.... "
