Yup 3440x1440 is pretty easy to run with a high end gpu despite what
one will have you believe

However, with the AW being 175hz, 3080 nor any gpu except probably the 4090 doesn't have the grunt to hit that unless as mentioned, you use a lower preset of dlss or/and reduce settings, it's actually easier to hit a locked 4k/60 than it is to push a constant 100+, let alone 140+ @ 3440x1440, even when using dlss quality.
Exactly and gotham knights being another recent one (although poorly optimised by the looks of it).
