Is Ultimate worth it for a casual player playing 4K ?

Hi everyone,

I'm a casual gamer hesitating between GFN Performance and Ultimate. Never used it before.

For context I just bought a 27" 4K, 160Hz monitor.

Since the Performance tier is capped at 1440p and 60 FPS, I have a few questions:

- Does a 1440p stream look blurry/bad on a 27" 4K screen, especially for text and UI?

- Can the Performance tier maintain a solid 60 FPS at "High" settings (with Ray Tracing)? For cyberpunk 2077

Asking because paying double for ultimate is a lot of money but I know I will regret not paying for it if 1440p feels bad on my monitor.

Thanks!
