Release: 0.7.20
Recommended nVidia proprietary driver branch 550+ for best compatibility with OptiX and CUDA.
CUDA SDK >11.5 should now mostly be supported. There can still be missing functions
Added CUFFT helper library for FFT functions when running SDK 12.3 and newer
See https://github.com/SveSop/nvidia-libs#helper-lib-usage below for usage
Older drivers that does not support SDK 10 and older may also fail/crash. Report any crashes with
logs on the issue page. However these are highly outdated drivers in general and will probably not
see too much attention in that regard.
Create logs typically with: WINEDEBUG=-all,+nvcuda,+nvml wine ./yourapp.exe > yourapp.log 2>&1
Also see notes about DXVK-NVAPI below for logging.
Library contains:
nvapi (dxvk-nvapi)
nvcuda (staging)
nvml (wine-nvml)
nvoptix (wine-nvoptix)
./package-release.sh name destdir
You can install symlinks and dll-overrides to the libraries in your wineprefix like this:
WINEPREFIX=/your/wine/prefix ./setup_nvlibs.sh install
To uninstall:
WINEPREFIX=/your/wine/prefix ./setup_nvlibs.sh uninstall
Check out README file usage of DXVK-NVAPI.
https://github.com/SveSop/dxvk-nvapi/blob/master/README.md
Typical log level usage:
DXVK_NVAPI_LOG_LEVEL=none (Default) No output.
DXVK_NVAPI_LOG_LEVEL=info Informational output of function calls.
DXVK_NVAPI_LOG_LEVEL=trace Detailed debug information.
For misbehaving games that do not work too well with DLSS or otherwise do not work with
the detected architecture, you can override detected architecture like this:
DXVK_NVAPI_GPU_ARCH= with one of the following options:
GK100 (Kepler)
GM200 (Maxwell)
GP100 (Pascal)
GV100 (Volta)
TU100 (Turing)
GA100 (Ampere)
AD100 (Ada)
Known games that needs override:
Monster Hunter World : DXVK_NVAPI_GPU_ARCH=GP100
War Thunder : DXVK_NVAPI_GPU_ARCH=GP100
Ghost of Tsushima : DXVK_NVAPI_GPU_ARCH=GA100
In order to use DXVK-NVAPI (NvAPI) with some extra GPU information (temps and the likes)
you need to copy the NVML binaries to your wine binaries folder. You can do this by
running the included nvml_setup.sh script. NVML is only available as 64-bit
See the Readme_nvml.txt file.
You can run tests of your adapter and functions by running the test case file:
WINEPREFIX=/your/wine/prefix wine bin/nvapi64-tests.exe
PS. You must install said libraryfile in your WINEPREFIX (see above)
You can drop-in the libraries in Proton8 - Experimental or GE-Proton-8 or newer like this:
PROTON_LIBS='$HOME/.steam/compatibilitytools.d/Proton-8.27-GE' ./proton_setup.sh
This will replace or add the libs to Proton for use with games.
The installscript is no longer compatible with older Proton-6.3 or Proton-GE-6/7 versions.
OBS!
You can add:
"DXVK_ENABLE_NVAPI": "1",
"PROTON_ENABLE_NVAPI": "1",
to your user_settings.py script in the proton folder eg:
PROTON_LIBS='$HOME/.steam/compatibilitytools.d/GE-Proton-8.27/user_settings.py'
Or you can run the game with PROTON_ENABLE_NVAPI=1 DXVK_ENABLE_NVAPI=1 %command%
Some additional tweaks may be required depending on game used and version of Proton.
To use FFT helper library cufft64_11.dll when running CUDA 12.3 or newer, simply
symlink the binary to the same folder where the executable you are running like this:
ln -sf nvidia-libs-release\lib64\wine\x86_64-unix\cufft64_11.dll.so cufft64_11.dll
NB. You should probably make a backup of the original cufft64_11.dll in that folder.
This however requires CUDA SDK 12.3 or newer to be installed on your system!
Newest CUDA SDK toolkit can be downloaded here:
https://developer.nvidia.com/cuda-downloads
Some older SDK samples can be run by specifying LD_LIBRARY_PATH to the system folder
where libcuda.so.1 and other libnvidia-xxx.so libraries reside. This varies depending
on distro. Ubuntu typicall uses /lib/x86-64-linux-gnu/ for 64-bit and
/lib/i386-linux-gnu/ for 32-bit.
For instance to get the NVIDIA SuperSonic Sled demo to run on Ubuntu you can load wine
with using LD_LIBRARY_PATH=/lib/i386-linux-gnu:$LD_LIBRARY_PATH
In case you do NOT use nvml (wine-nvml) library to emulate nvml.dll, DAZ Studio will
show 2 "adapters" for rending. Choose the one that show your GPU name, and NOT the other.
NVML can be installed by using the setup_nvml.sh script included in the package and for
DAZ Studio is recommended.
