The issue is very much multidimensional and related also a lot to how GPU manufacturers have been promoting their RT enabled cards at specific prices at specific specs combined with how game companies were trying to showcase the best games ever visually with those cards.This is such a good point. Not only does it remove anxiety on the end user who fears that they’re missing out on some amazing IQ improvement going from ultra to medium. It also encourages developers to be more thoughtful about the settings they ship. Maybe you don’t include an ultra setting for some feature where the IQ improvement is imperceptible because you know your settings menu preview will make that obvious.
I am a huge fan of unobtainium settings in games because by the time I get around to playing the game it’s no longer unobtainium. But you got to feed that ultra settings ego trip.
Once the RTX cards hit the market for example, NVIDIA withdrew it's high end GTX cards from the market which were pretty powerful on rasterization and very competitive with the RTX cards with RT off. The 1080ti for example could beat some of these cards with RT off since it was fast and had more VRAM.
The RTX cards were sold at high end prices that can do RT compared to their previous cards but not clear wins in all specs or powerful enough to run the target specs that devs had in mind for gamers to hit the desired performance.
For example you bought your new awesome RTX card with a premium tag price to enjoy RT visuals but VRAM size didn't see the jump. Sometimes VRAM requirements of many games jumped much higher
So on one hand you had those fast cards for RT but not enough VRAM to run games buttersmooth and without hiccups. So a lot of gamers are hyped up by marketing material, both by GPU manufacturers and game companies about the awesome perfect next gen visuals offered by those RT graphics, and awesome performance thanks to those awesome expensive super powerful cards we have never seen before. But in reality they are caught in a strange situation where they get RT (which is the reason why these cards hit the market in the first place) but the cards lack somewhere else to offer that experience smoothly so they start lowering settings with RT on, or have RT off to ha e some other settings higer. It's a situation where you are convinced you can have the cake and fully eat it but you actually cant. Or it's like having the fastest luxury supersport car ever developed with Rocket Turbo tech perfect for 418 Miles Per Hour in a highway being marketed to you, but once you buy it you discover the road it's put on is bumpy, is filled with debris, traffic lights and road blocks and there the experience is far from being the same as the marketing material. The tech is still awesome. But tough luck. But if you want to fully eat your cake and have that marketed experience there is that even more super expensive card that can traverse those roads too.
