 | 1 minami 187 天前 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 |
 | 2 Cooky 187 天前 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 |
 | 3 lostsquirrelX OP  单独用 4060 会用掉接近 4G 显存 ``` ========== VULKANINFO ========== Vulkan Instance Version: 1.3.275 Instance Extensions: count = 24 ------------------------------- VK_EXT_acquire_drm_display : extension revision 1 VK_EXT_acquire_xlib_display : extension revision 1 VK_EXT_debug_report : extension revision 10 VK_EXT_debug_utils : extension revision 2 VK_EXT_direct_mode_display : extension revision 1 VK_EXT_display_surface_counter : extension revision 1 VK_EXT_headless_surface : extension revision 1 VK_EXT_surface_maintenance1 : extension revision 1 VK_EXT_swapchain_colorspace : extension revision 4 VK_KHR_device_group_creation : extension revision 1 VK_KHR_display : extension revision 23 VK_KHR_external_fence_capabilities : extension revision 1 VK_KHR_external_memory_capabilities : extension revision 1 VK_KHR_external_semaphore_capabilities : extension revision 1 VK_KHR_get_display_properties2 : extension revision 1 VK_KHR_get_physical_device_properties2 : extension revision 2 VK_KHR_get_surface_capabilities2 : extension revision 1 VK_KHR_portability_enumeration : extension revision 1 VK_KHR_surface : extension revision 25 VK_KHR_surface_protected_capabilities : extension revision 1 VK_KHR_wayland_surface : extension revision 6 VK_KHR_xcb_surface : extension revision 6 VK_KHR_xlib_surface : extension revision 6 VK_LUNARG_direct_driver_loading : extension revision 1 Instance Layers: count = 4 -------------------------- VK_LAYER_INTEL_nullhw INTEL NULL HW 1.1.73 version 1 VK_LAYER_MESA_device_select Linux device selection layer 1.3.211 version 1 VK_LAYER_MESA_overlay Mesa Overlay layer 1.3.211 version 1 VK_LAYER_NV_optimus NVIDIA Optimus layer 1.3.289 version 1 Devices: ======== GPU0: apiVersion = 1.3.289 driverVersion = 565.57.1.0 vendorID = 0x10de deviceID = 0x1402 deviceType = PHYSICAL_DEVICE_TYPE_DISCRETE_GPU deviceName = NVIDIA GeForce GTX 950 driverID = DRIVER_ID_NVIDIA_PROPRIETARY driverName = NVIDIA driverInfo = 565.57.01 cOnformanceVersion= 1.3.8.2 deviceUUID = ad9f8da0-34f7-1e2e-1a70-25ed43366436 driverUUID = a40eb34f-a796-5990-89ac-95d78eb83699 GPU1: apiVersion = 1.3.289 driverVersion = 565.57.1.0 vendorID = 0x10de deviceID = 0x2803 deviceType = PHYSICAL_DEVICE_TYPE_DISCRETE_GPU driverID = DRIVER_ID_NVIDIA_PROPRIETARY driverName = NVIDIA driverInfo = 565.57.01 cOnformanceVersion= 1.3.8.2 deviceUUID = cdc14bed-22a8-460e-2c40-dd22939b2988 driverUUID = a40eb34f-a796-5990-89ac-95d78eb83699 GPU2: apiVersion = 1.3.289 driverVersion = 0.0.1 vendorID = 0x10005 deviceID = 0x0000 deviceType = PHYSICAL_DEVICE_TYPE_CPU deviceName = llvmpipe (LLVM 19.1.1, 256 bits) driverID = DRIVER_ID_MESA_LLVMPIPE driverName = llvmpipe driverInfo = Mesa 24.2.8-1ubuntu1~24.04.1 (LLVM 19.1.1) cOnformanceVersion= 1.3.1.1 deviceUUID = 6d657361-3234-2e32-2e38-2d3175627500 driverUUID = 6c6c766d-7069-7065-5555-494400000000 ``` |
| 4 Cooky 187 天前 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 https://download.nvidia.com/XFree86/Linux-x86_64/435.17/README/primerenderoffload.html |
| 5 Cooky 187 天前 你再找找 llvmpipe 这个驱动是哪个包的，看看能不能把它卸载了 |
| 6 lostsquirrelX OP 感谢 @Cooky ，我试试 |
| 7 lostsquirrelX OP 禁用 llvmpipe 感觉卡顿感有改善，考虑还是收张 2060 替换了 |
