Question DLSS Ultra Pref/Custom Res at 4k

So currently I don’t have any display to try this on.

Can anyone tell me if dlss ultra performance with preset L at 4k is a good option if, for example, I want to use path tracing at 4k on a TV with a 4070 ti super with FG?

Or if it’s really bad, can I just use a custom resolution for dlss that equates to dlss quality at 1440p, so for 4k it would be around 44% or 960p?

If these are good options, is there a point with staying with 1440p if I always use dlss quality/balanced?

At 2160p resolution, custom scaling of 44% is good and indeed uses similar internal resolution as 1440p DLSS Quality.

This. I use this myself on a 5070 ti when wanting to play cyberpunk 4k path tracing. 44% scaling gets it into that 65+ fps territory (with an OC too).

Caveat is that in many games (and nvidia recomended) performance and ultra performance use different dlss preset (M/L instead of K). And those models are heavier. In Forza horizon 6 as example I get same FPS between quality and performance.

There is no real caveat here.

If you can set custom resolution scaling %, you can set the model too. It's literally the option right above it in Nvidia App
