Why is my Nvidia driver unable to load Optix library?
Unable to load optix library, NVIDIA driver 431.70 is too old (CPU-rendering with Optix GPU-denoiser) Attachments: Up to 5 attachments (including images) can be used with a maximum of 2.0 MiB each and 9.8 MiB total. This can also happen if the Optix library is missing from the NVidia driver install.

Why does preventing cycles crash after CUDA timeout?
Normally, this system is great because it prevents permanent screen freezes for malfunctioning drivers or games. But in Cycles, one sample is considered one computation, which means that if your sample calculation takes longer than two seconds, Cycles (and the Blender UI, if you render with UI) will crash.
Why does my GPU stop rendering in Windows 10?
The problem here is that Windows has a timeout detection and recovery (TDR) system that detects if a GPU computation takes longer than a given amount of time, the default value for that being two seconds, and then “reinitializes” the Windows Display Driver Model (WDDM) driver and resets the GPU. This will stop the rendering process.
What should be the value of tdrdelay in CUDA?
If the folder contains a key with the name “TdrDelay”, right-click it and change the value to something high enough for your scene. Something between 8 and 16 should be fine, the number is interpreted as seconds. And be aware of the difference between a decimal and a hexadecimal input.
