I know but both cards handle 1440p ok (My 3840x1080p resolution is roughly in the ballpark of 1440p). You just end up dropping to Mixed High/Ultra instead of Ultra settings to get the same frame rates back up. Like 90+% of the time, you will not notice that difference anyway. It's why optimized settings are a thing.
RTing is another matter. Without DLSS your kinda stuck. It's barely, to not really, usable. With FSR/RSR it becomes usable, but FSR/RSR tech isn't a DLSS. So your making a compromise that might not be worth it for the RT. Especially given that these cards play in 1080p/1440p land and not 4k.
So while they have the feature, they aren't really powerful enough to use it. Which isn't surprising given they are lower tier cards.
