Nvidia GPU not detected on Windows 11

[BolverBlitz]

My System got
CPU: Ryzen 9 7950X3D + Integrated GPU (128GB)
GPU: RTX 3090 (24GB)

I see no manual config option, so i run it with python3 ./exo/main.py, it seems to work and downloads models.
But it claims it uses 128GB and 0TFLOPS so its not using the RTX Card.

I´ve also added CUDA=1 to my env as some people on linux sugested in issues $env:CUDA = "1"

nvcc --version

hi there, an issue that i've had myself a lot of times is that sometimes the casing inside the exo/exo/topology/device_capabilities.py might not be the same as what gets detected.
For your case:
Your GPU name is: NVIDIA GeForce RTX 3090
but inside said file it's called:

"NVIDIA GEFORCE RTX 3090": DeviceFlops(fp32=35.6*TFLOPS, fp16=71.2*TFLOPS, int8=142.4*TFLOPS),
"NVIDIA GEFORCE RTX 3090 TI": DeviceFlops(fp32=40.0*TFLOPS, fp16=80.0*TFLOPS, int8=160.0*TFLOPS),
# RTX 20 series
"NVIDIA GEFORCE RTX 2060": DeviceFlops(fp32=6.45*TFLOPS, fp16=12.9*TFLOPS, int8=25.8*TFLOPS),

so maybe try to modify that file yourself, exo/exo/topology/device_capabilities.py LINE: 86 to
"NVIDIA GeForce RTX 3090": DeviceFlops(fp32=35.6*TFLOPS, fp16=71.2*TFLOPS, int8=142.4*TFLOPS)

same here on Ubuntu 24.04, CPU: Ryzen 9 5950X + Integrated GPU (128GB)
GPU: RTX 3090 Ti(24GB)

Make sure you install CUDA drivers if you're using WSL and Ubuntu. Immediately fixed it for me:

https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&Distribution=WSL-Ubuntu&target_version=2.0&target_type=deb_local

wget https://developer.download.nvidia.com/compute/cuda/repos/wsl-ubuntu/x86_64/cuda-wsl-ubuntu.pin
sudo mv cuda-wsl-ubuntu.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget https://developer.download.nvidia.com/compute/cuda/12.8.0/local_installers/cuda-repo-wsl-ubuntu-12-8-local_12.8.0-1_amd64.deb
sudo dpkg -i cuda-repo-wsl-ubuntu-12-8-local_12.8.0-1_amd64.deb
sudo cp /var/cuda-repo-wsl-ubuntu-12-8-local/cuda-*-keyring.gpg /usr/share/keyrings/
sudo apt-get update
sudo apt-get -y install cuda-toolkit-12-8
