DDU and Nvidia CUDA, Nsight, Cudnn

Post by Lion200223 »

I only found this topic:
viewtopic.php?t=1296

What's the actual state of DDU against CUDA, nsight and cudnn? Does it delete them in a correct way? Does it leave them as garbage files? Or maybe it does not touch them at all and only uninstalls the main gpu driver? What about the paths?

Thank you!

It does not remove the sdk anymore, it only concentrate on the driver.
So technically , you use DDU to wipe the nvidia driver and then install a newer or older driver and all the cuda, nsight stuff should still work.
If you notice anything wrong tell me and I'll fix it, but from what I know it's working correctly.

From what I understand, DDU (Display Driver Uninstaller) mainly focuses on removing GPU driver components, registry entries, and related services. It typically doesn’t fully remove development tools like CUDA, Nsight, or cuDNN since those are installed separately and may be used without the driver package. In most cases, their files and paths remain intact unless they were bundled with the driver installation. If you want a completely clean environment for CUDA development, it’s usually better to uninstall CUDA Toolkit and related components separately after running DDU.
