XD以下折腾超过12小时Orz
=》目的是想要躺着用Steam Deck打MVP baseball 2005^_^
(1)、首先在Steam Deck使用双系统灌windows 11 2H22。
=〉windows 11 2H22 版本没问题，
因为我的桌机可以正常游玩。
#但是始终会出现“MVP Baseball 2005 requires DirectX 9 and hardware graphics acce
leration”的错误讯息。
(2)、已安装了：
=》所有Steam deck提供的最新驱动程式。
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。
原本怀疑是0405不支援部分DirectX 9的游戏，但我使用Steam Deck下的win11安装Ste
am ，测试了仙剑奇侠传四可以玩。
=》仙四的要求DirectX版本：9.0c。
想请教大家有遇过类似的问题并且顺利解决的吗？谢谢
目前猜测是显卡驱动程式的关系，
AMD有说目前AMD的自动更新程式还不支援0405。

=》有查到Direct3D加速要打开。
=》有查到MVP MODS的文章说明，
但Steam deck没有可以这样的调整分辨率方式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.
