I have both an rtx 3090 and a 6900xt, both have good and bad points, but nvidia drivers are neither godlike nor troublefree and the interface is ancient. Amd drivers are very similar but the interface is a world apart and far better
All subjective. All truthful to the people with issues or none.
I have had GPU's die on both camps. XFX HD 7770 and EVGA GTX 480.
The biggest trouble was always with Radeon. The only cards to give me next to zero problems were the R9 Fury and RX 480/570.
Biggest issue with Nvidia for me was BF3 with texture discolouration. Not sure if anyone remembers the render bugs in BF3?
Never had a problem with Nvidia that was more than just "use the last driver."
Radeon: DDU because the installer is incapable. No fix.
Black screens on multiple monitor use.
Trash game supports for anything that is not a AAA release within the DX11 period and that's being generous.
Frame stuttering for no reason.
D3D device hung.
Radeon settings has stopped working followed by a BSOD.
Enabling TDR in reg edit.
If none of the fix's work and you have stopped all extra software on your PC from interfering even the ones supplied in the Radeon driver, there is only way and yeah the grass is greener for real.
