由于某种原因，大多数（如果不是全部）游戏的视频内存 (VRAM) 都仅限于 384MB，而不是完整的 2048MB 专用内存。我读到过一些文章说，在 OpenGL 菜单中禁用“与 VBlank 同步”可以解决此问题，但事实并非如此。那么，这可能是什么原因造成的呢？
请注意，所有测试的 3D 应用程序均使用 Wine 1.5.26 运行，使用 AMD Catalyst 13.1、13.2 和 13.3-beta3 的 PlayOnLinux 4.0.14 会随机崩溃，表明存在显存不足或者应用程序错误有一致，这让我对 Ubuntu 的第一印象非常没有效率、功能有限，最重要的是无法玩。

这个问题有解决办法吗？如何让 Linux 或 3D 应用程序意识到我的 HD6970 有更多专用视频内存可用？是否有适合此类问题的命令，或者是否有其他应用程序（如 Wine/PlayOnLinux）可以更好地利用我的应用程序和全部内存？
Ubuntu 只显示 256mb 的 vram，而实际应该是 1GB
