I recently got this having tried a few others in the past and I can’t fault this one. It’s excellent!

Do not get the Razor! I got one and have had nothing but problems and now it flat out just doesn’t work. I bough the 8bitdo equivalent and it’s awesome. https://amzn.eu/d/b1tmLi9, neither are that compact though. It looks like there are a fair few recommendations so I’m sure you’ll find something, just dont get the Razor.

Oh totally. Reason I ask is I’m running a 4090 with dlss and FG and running ultra (think it’s called something different) at 4k and getting 90 fps.

Hey, I’m interested. Do you have frame gen on and dlss and still getting 40fps?
