当我尝试玩游戏时，bumblebee 出现了问题。我安装了 TF2、CS:GO、DotA 2 等原生 Linux 游戏……但性能非常差。
Linux Dist. 是 Ubuntu 16.04 LTS。使用 Nvidia 驱动程序 390。
没有 bumblebee / 只有 nvidia 驱动程序，我在 CS:GO 上获得 150-200 fps。使用 bumblebee + nvidia 驱动程序 -> 我在 CS:GO 上获得 70-120 fps 我的 CS:GO 启动选项：
LD_PRELOAD="libpthread.so.0 libGL.so.1" __GL_THREADED_OPTIMIZATIONS=1 vblank_mode=0 optirun -b primus %command%
我尝试不使用命令让大黄蜂真正发挥作用，在 CS:GO 上使用 Intel HD 时，帧率为 30-50 fps。我的显卡是：
00:02.0 VGA compatible controller: Intel Corporation Skylake Integrated Graphics (rev 06)
01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 950M] (rev ff)

我的 xorg.conf 文件是空的，我不知道为什么，因为我创建了它。
答案1
如果我理解正确的话，这是 Bumblebee 的正常行为。每一帧都从后台运行的一个 Xserver 复制到当前使用英特尔显卡运行的 Xserver，并同步到显示器刷新率，例如 60hz。因此，您永远不会获得超过 60fps 的合成。整个帧复制过程会使速度变得更慢。但是，我可能错了。
答案2
好的，我切换到 Nvidia Prime 来选择显卡。清除了大黄蜂。它的性能很差。
