$70 is dirt cheap? So far it runs kinda like shit on both Nvidia and Intel GPUs, and it runs slightly better on AMD cards for some reason.
Honestly this is Bethesda's standard move, they make a poorly optimized game that runs like shit and just let the modders fix it for them. They've been doing it for decades now, I don't know why anyone is surprised.
It runs better on AMD cards because they and Bethesda entered into an exclusive partnership for the game. FSR is AMD tech; it's why DSLL isn't an included option.
Thankfully, it's quite simple to replace FSR with DSLL using a mod. I get 45-60 FPS on High @ 3440x1440 with a 2070S after doing so.
