• Some people recommend using DDU to completely remove the driver before installing a new GPU.

• Some others say that just installing the new driver from NVIDIA/AMD is enough, no need for DDU.

• In reality, does having an old driver affect performance or stability?

• Has anyone ever had problems not using DDU before changing the GPU?

• Is DDU really necessary in this case, or is it only useful when the system has errors?

I am about to upgrade my PC, changing from a GTX card to a new RTX card. I see many conflicting opinions:

• Some people recommend using DDU to completely remove the driver before installing a new GPU.

• Some others say that just installing the new driver from NVIDIA/AMD is enough, no need for DDU.

What I am wondering is:

• In reality, does having an old driver affect performance or stability?

• Has anyone ever had problems not using DDU before changing the GPU?

• Is DDU really necessary in this case, or is it only useful when the system has errors?

I want to consult the community to make the safest and most optimal choice.

Thank you, everyone, for sharing your experiences!
