分享CAS優化WIN7登錄檔

zoneaudio

我都係爬文回來試的,唔好問我係咩野來,只知道是用來優化音質,
自己試左改善十分明顯,每種樂器聲音更加獨立,
層次感有大改善,低音不再糊作一團,
整體發聲相當圓潤自然,個人覺得有很大程度提昇,
連帶睇戲也得到提昇真係好掂,最重要是免費的 !  !

->可能有朋友問用Fidelizer得啦,洗嘜攪咁多野,
    咁你繼續用啦最緊要o岩自己!!
=================================================
聽歌,睇戲測試分別是Foobar,MPC-BE +LAV filter再去
-->非同步Usb TO I2S-->WM8741 DAC(輸出是MUSE 01 x2 )
-->6922膽前-->2A3 2w+2w膽後-->MarkAudio 4"full range speaker

溫馨提示我的電腦是獨立CAS使用已經將無謂野解除安裝,
包括I.E.8.....等等,同埋用最簡單介面,沒有華麗既外觀(呢D會污染音質)
=================================================
有興趣既朋友可以一試,因為要修改登錄檔,
警告:請先備份你的系統
本人一概不會負責的
------------------------------------------
1.BIOS ENABLE HPET

在Win用Admin身份執行"命令提示字完"鍵入
bcdedit /set useplatformclock true

REBOOT
-----------------------------------------------------------------------
2.開兩個文件檔file_1.txt,file_2.txt
將下面兩段虛線內文字分別貼上(不要复制虛線)
然後修改檔尾file_1.txt,file_2.txt為file_1.reg,file_2.reg
雙擊執行後reboot就可以

file_1.txt

Thank you

會否撞其他東西?看來真系要BACK UP左個SYSTEM先,安全D

應該唔會,只是將音效既優先權推高,而無謂野就推低,
同埋開左HPET(高精度時鐘)係咁多野

...

是用記事簿先開file_1.txt,file_2.txt後再改為file_1.reg,file_2.reg,然後再激活RIGHT?

第一個係配合bios入面既高精度計時器(HPET)
因為就算bios開左HPET， windows都會用system clock, 咁樣效率最差，比唔開仲衰，所以要打返果句command enable佢

個人覺得開唔開HPET睇口味，我自己係disable既

file_1.txt係改MMCSS呢個service 分配唔同profile既priority，只對WASAPI有影響，一般播放軟件會用pro audio or audio，例如foobar等等，所以只改pro audio同audio都ok

file_2.txt果D就真係一D非常濕碎既野，例如disable superfetch呢D狂read write HDD既service
Win32PrioritySeparation係gui都有得set，程序優先定背景服務優先
ballontips關氣泡提示等等

溫馨提示，fidelizer都有做MMCSS profile alternation，用緊fidelizer無必要再改
