Question Switching new GPU

[DiseasedPride]

About a week ago, bought a new RX 6700 non XT GPU and installed it on my PC, removing my old RTX 3050, after installing the new GPU and turning on my PC, the ne GPU started working and showed on my Task Manager as GPU 0, even though when I start a game on Steam it shows GPU Usage 99%, what concerns me is that why it won't show as GPU 1?
BTW I did not use DDU just uninstalled the Nvidia drives from Control Panel and installed the new AMD Drives, should I use DDU to remove the AMD drivers and install them again, maybe the GPU show as GPU 1?

Thanks for any answers!

Yes. When installing your GPU drivers, after DDU, manually install in an elevated command, i.e, Right click installer>Run as Administrator.

It'd be a good idea to list the specs to your build like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU, apart from it's make and model.

Before you installed the new gpu you should have used DDU there's even an option made for who is switching gpu's.

Showing GPU 0 is normal, mine is the same. If you have two disks it will show disk 0 and disk 1.

Use DDU in safe mode to unninstall both nvidia and amd drivers then restart and install amd drivers again.

Why would it show as GPU 0? You have only one GPU installed so naturally it will show as 0. If you had two then they would be shown as GPU 0 and GPU 1.
