If multiple gpus are available, display a "select gpu" dropdown list in ImGui.
Description
If multiple gpus are available, we have the --gpu <index> command line which allows the user to specify which gpu will be picked. (The code will validate that the chosen index is valid and that the chosen gpu is suitable for the application's purpose). However, there is no way of switching the gpu at runtime.
In my system, I have an AMD 7950X with an internal gpu chip (VK_PHYSICAL_DEVICE_TYPE_INTEGRATED_GPU) and an Intel Arc A770 16GB (VK_PHYSICAL_DEVICE_TYPE_DISCRETE_GPU).
Alternatives
Do not implement this.
Affected Code
UI rendering
Operating System
all
Additional Context
Switching to another gpu should not be difficult. You simply shut down the engine and restart it with the new gpu. To create the list, you must enumerate the physical devices and store both the index and the name of it.
