首先我想说的是，我是 Ubuntu 新手（以前是 Windows 用户），所以这可能是一个新手问题。顺便说一句，我曾尝试使用 Heroic Games Launcher 玩 Rocket League，但性能很糟糕。我确定我使用的是 Intel 集成显卡，而不是 Nvidia GPU。以下是我的总体规格：
英特尔 i5 8500 3 GHz GTX 1060 6GB 16GB RAM 2666 (2x8)
在 Windows 中，我可以使用 Rocket League Maximum Graphics 稳定地获得 +85 fps，而在 Ubuntu 中，我从未获得超过 15 fps 的速度。当我打开系统监视器时，出于某种原因，我看不到 GPU。因此，我谷歌搜索了如何查看我的 PCI 连接，然后我看到了这个

我的 PCI 桥不是应该由 Nvidia 控制吗？我该如何更改它？
