Current known issues

  • See the Nvidia section of our latest news for the ways in which Nvidia is being special today.

Crash when taking shield damage in-game

  • There is a shield rendering bug that causes the game to crash. It seems to affect 1000 series cards.
  • There is currently no known workaround other than switching cards. We recommend AMD.

Typically caused by dxvk being broken or not installed

  • Use the LUG Helper to update dxvk

Game fails to start after clicking Launch Game on laptops with Nvidia GPU + intel graphics

  • Errors may include
    DXVAVDA fatal error: could not LoadLibrary: msvproc.dll
    or
    Major opcode of failed request: 156 (NV-GLX)
  • Try removing all optimus/prime env vars for render offload and set the Vulkan device to the Nvidia GPU.
    • identify device name using command vulkaninfo --summary | grep deviceName
    • set device name with environment variable DXVK_FILTER_DEVICE_NAME=yourdevicenamehere

Severe frame drops

  • Some Penguins are seeing VRAM exhaustion problems on nvidia cards
  • Add a new DXVK_CONFIG environment variable to override the max device memory.
    Refer to DXVK config for examples
    • Card with 12GB vram 
       export DXVK_CONFIG="dxgi.maxDeviceMemory = 9216;cachedDynamicResources = a;"
    • Card with 10GB vram 
       export DXVK_CONFIG="dxgi.maxDeviceMemory = 8192;cachedDynamicResources = a;"
    • Card with 8GB vram 
       export DXVK_CONFIG="dxgi.maxDeviceMemory = 6144;cachedDynamicResources = a;"
    • Card with 6GB vram 
       export DXVK_CONFIG="dxgi.maxDeviceMemory = 4096;cachedDynamicResources = a;"
    • Card with 4GB vram 
       export DXVK_CONFIG="dxgi.maxDeviceMemory = 2048;cachedDynamicResources = a;"

DLSS (Deep Learning Super Sampling)

  1. Use the latest LUG Helper to install a standard (non-staging) LUG-Wine runner. (For wine-staging: there is a memory allocation issue with libcuda + wine-staging and Easy Anti-Cheat makes this prohibitively difficult to overcome)
  2. Install winetricks 20250102-next or newer. System winetricks can be updated with
    sudo winetricks --self-update
  3. Enter a Wine maintenance shell for your prefix using the sc-launch.sh script.
  4. Install dxvk >=2.6.2 and dxvk_nvapi >=0.9 into your wine prefix with the following command:
    1. winetricks -f dxvk dxvk_nvapi
    2. Note: If you do not use the Helper’s Wine maintenance shell, you’ll need to prepend WINEPREFIX=/path/to/star-citizen/prefix to the above command!
  5. To enable DLSS 4, add the following environment variables. In the Helper’s Maintenance menu, select the Edit launch script option 
    export PROTON_ENABLE_NGX_UPDATER="1" 
export DXVK_NVAPI_DRS_NGX_DLSS_SR_OVERRIDE="on"
export DXVK_NVAPI_DRS_NGX_DLSS_RR_OVERRIDE="on"
export DXVK_NVAPI_DRS_NGX_DLSS_FG_OVERRIDE="on"
export DXVK_NVAPI_DRS_NGX_DLSS_SR_OVERRIDE_RENDER_PRESET_SELECTION="render_preset_latest"
export DXVK_NVAPI_DRS_NGX_DLSS_RR_OVERRIDE_RENDER_PRESET_SELECTION="render_preset_latest"
  6. To confirm DLSSv4 is working, enable the debug overlay env var and look for it in-game to say Render Preset: K or DLSSv3 v310.x+ 
    export DXVK_NVAPI_SET_NGX_DEBUG_OPTIONS="DLSSIndicator=1024,DLSSGIndicator=2"
  7. Disable the debug overlay when done by changing the above env var to: 
    export DXVK_NVAPI_SET_NGX_DEBUG_OPTIONS="DLSSIndicator=1,DLSSGIndicator=1"
  8. Note that nvidia driver v575 may be unstable. v570 is recommended for stability.

Gamescope not working

  • See this known issue report.
  • A possible fix is to set the environment variable __GL_THREADED_OPTIMIZATIONS=0
