我有一台顶级机器，在 Windows 上可以非常快速地运行 Stellaris，但在 Ubuntu 18.04 上，stellaris 的运行速度非常慢，就像没有使用显卡一样。我使用的是 nvidia 卡。
在 dmesg 中看到这个，不确定是否相关。我猜是无关的，因为它似乎在不到一秒的时间内发生？：

答案1
我刚刚安装了最新的 nVidia 驱动程序（软件和更新 > 附加驱动程序 > nVidia）或sudo apt install nvidia-current
但当我重新启动时，一切都变黑了，因为我使用的是 Optimus 卡（用于笔记本电脑节能的混合 nvidia/intel GPU），所以我安装了 prime:
sudo apt install nvidia-prime并通过设置正确的 GPU nvidia-settings（它是英特尔的），然后再次重新启动，一切都运行良好！游戏运行良好！
