Eh, not caring too much about frame rates can be healthy in terms of how long you go between upgrades. Which could have a knock on effect of forcing devs to more often consider weaker builds as people don't upgrade as often

Just depends on how you approach it. If you have relatively new parts, then yeah, you should expect at least 60 FPS. If you have an older system, then the only thing that matters is that it's still enjoyable
