ubuntu 加显卡后感觉动画卡顿

把 950 扔了，留着干啥，新的 n 卡开源驱动都不支持 950 了。为了减少 GUI 开销吗，你也太看不起 4060Ti 了

你这俩用的应该都是同一个驱动？看看驱动版本
再看看 vulkan 认出来几个显卡
vulkaninfo --summary

 单独用 4060 会用掉接近 4G 显存

把这个变量设置成 0 试试，全局的，加 bashrc 里看看
export __NV_PRIME_RENDER_OFFLOAD=0

你再找找 llvmpipe 这个驱动是哪个包的，看看能不能把它卸载了

感谢 @Cooky ，我试试

禁用 llvmpipe 感觉卡顿感有改善，考虑还是收张 2060 替换了
