Ubuntu 22.04下技嘉RTX 4070显卡性能异常(游戏及GLXgears帧率极低)排查求助
大家好,我最近在搭载Z490主板的Ubuntu 22.04系统上安装了一块技嘉RTX 4070显卡,通过software-properties-gtk工具安装了535版本的NVIDIA驱动。目前看YouTube高清视频完全正常,但运行唯一的游戏X-plane时帧率低到几乎为0,就连glxgears也只有60FPS。我现在搞不清这是PCIe 4.0显卡和3.0主板的兼容性问题,还是驱动安装/配置环节出了问题,想请社区的大佬帮忙排查一下。
下面是我收集的系统相关信息:
- 显卡厂商信息(执行命令:
hwinfo --gfxcard |grep "Vendor"):Vendor: pci 0x10de "nVidia Corporation" SubVendor: pci 0x1458 "Gigabyte Technology Co., Ltd" - PCIe显示设备信息(执行命令:

有没有大佬能帮我分析下问题出在哪?先谢过大家了!
