You could do some sort of adaptive quality where you spend time incrementally improving fidelity until your frame budget is up. In practice I think that might be trickier than it sounds, but I feel like theoretically there's something there that could get you the best graphics your rig can handle without dropping frames. I've been considering doing something like this when I've been building a game/engine lately.

There's only so high you can go because the game assets have a maximum quality. Maybe you'll be able to max out the 5090 but what about the next flagship GPU?

You're also likely not going to maximize all of bandwidth, compute, etc. because one of them will likely be your bottleneck. And it might be different depending on the GPU, too.

Most games are strictly scaled on resolution due to how deferred pipelines run. This is exactly the slider to max or not max everything on a gpu for games. The more pixels the more memory and the more compute.

[Rohansi]

If you're rendering at native resolution, which many PC gamers do, going higher isn't significantly better because it just helps with antialiasing via supersampling. There's no point rendering so much more pixels just because you can, that's just a waste of electricity.

The more pixels, the more compute of fragments but not necessarily more memory. A fragment might hit the same texel as an adjacent fragment.

Certainly not more from main memory, and maybe not more from the vram either depending on how the pipeline goes.

It's not a linear slider.
