RT，我原本是WIN7系统装的
现在觉得WIN7不好，就换回了XP，就出现了这个错误
错误报告：
Bad video card drivers!
-----------------------
Minecraft was unable to start because it failed to find an accelerated OpenGL mode.
This can usually be fixed by updating the video card drivers.

怎么搞啊

更新显卡驱动

驱动精灵更新显卡驱动

你点显示全部，然后把现在的显卡驱动备份之后重装。

介个？

驱精更显驱……

请更新显卡驱动。。。。

.............

可是我家其他版本的MC都能玩

不过我看一个集显玩mc。。。很吃力的样子。

为什么突然要装WinXP了= =这不是没事找事么= =

win7效果不错
