Works fine. Switched from 2070S, I used it at 4K with DLSS in Performance mode and FSR4 is a great replacement, I don't think DLSS is a reason to buy Nvidia anymore.

You can force FSR4 with OptiScaler in almost any DLSS/FSR2-3/XeSS game. I wouldn't use that in online multiplayer game with anti cheat, but otherwise, the multiplayer games have no issues running native 4K at 60 fps at least.

The drivers are stable, which is also ironic, since Nvidia's drivers this year shat the bed.

I didn't really try non-gaming stuff that stresses GPU
