"Enable GPU raytracing" doesn't work
i have a AMD rx 5700 xt graphics card
how to enable this option?

I use NVidia so can't confirm using an AMD card but this page suggests GPU raytracing requires NVidia hardware :

https://helpx.adobe.com/substance-3d-bake/features/gpu-raytracing.html  which states:

The DXR-accelerated ray tracing will automatically be enabled if the system follows these requirements:

• A compatible GPU is installed (RTX family, Titan V or Geforce 10xx)
• GPU drivers are up to date
• Windows 10 'Fall Creator' / October update (ver 1809) is installed

Also here: https://helpx.adobe.com/substance-3d-painter/technical-support/hardware-requirements.html

which states

GPU Raytracing for Baking

To enable GPU Raytracing via Optix or DXR the minimum drivers recommended above must be installed.

DXR requires the following minimum configuration as well:

• Windows 10 version 1809 (build number 10.0.17763), see this page for more information
• GPU with Pascal architecture (Nvidia GeForce 10XX)

GPU raytracing runs optimally on dedicated ray tracing hardware such as NVIDIA GeForce RTX or NVIDIA Quadro RTX GPUs.
