XD以下折騰超過12小時Orz
=》目的是想要躺著用Steam Deck打MVP baseball 2005^_^
(1)、首先在Steam Deck使用雙系統灌windows 11 2H22。
=〉windows 11 2H22 版本沒問題，
因為我的桌機可以正常遊玩。
#但是始終會出現「MVP Baseball 2005 requires DirectX 9 and hardware graphics acce
leration」的錯誤訊息。
(2)、已安裝了：
=》所有Steam deck提供的最新驅動程式。
https://help.steampowered.com/zh-tw/faqs/view/6121-ECCD-D643-BAA8
=》DirectX 9.0c。
=》DirectX End-User Runtime
https://www.microsoft.com/zh-tw/download/details.aspx?id=35
#Steam deck是用AMD Custom GPU 0405。
原本懷疑是0405不支援部分DirectX 9的遊戲，但我使用Steam Deck下的win11安裝Ste
am ，測試了仙劍奇俠傳四可以玩。
=》仙四的要求DirectX版本：9.0c。
想請教大家有遇過類似的問題並且順利解決的嗎？謝謝
目前猜測是顯卡驅動程式的關係，
AMD有說目前AMD的自動更新程式還不支援0405。

=》有查到Direct3D加速要打開。
=》有查到MVP MODS的文章說明，
但Steam deck沒有可以這樣的調整解析度方式XD

I have recently come across this problem my self. I found that other people hav
e had the same error message but no solution was ever found for them. With a lot
of trial and error I finally narrowed it down to my Resolution/Refresh rate. I
have an HDMI cable going from my video card to my TV. Inside the video propertie
s is a list of extra resolutions allowed by my HDMI(HD) as well as native PC res
olutions. The game would crash with "mvp baseball 2005 requires directx 9 and ha
rdware graphics acceleration" any time I had a resolution that used interlaced(3
0Hz) instead of progressive scan(60Hz). So 1080i,1920x1080(30Hz) would not work.
But 720p,1176x664 does work. As well as all the native PC resolutions. It took
me all day to figure this out so I thought I would(Hopefully) save somebody else
some time and effort. Hope this helps.
