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

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:lspci | egrep -i "vga|display|3d"):
    01:00.0 VGA compatible controller: NVIDIA Corporation Device 2786 (rev a1)
    
  • 视频硬件详细信息(执行命令:lshw -c video):
