60fps is likely off the table for CPU reasons. And the 30fps is stable most of the time as per DF; it typically drops if you sprint through the larger outdoor areas or engage large numbers of enemies in these areas, again suggesting that it's the CPU that's the limiting factor.

And dynamic 1080p while using the more demanding available DLSS model is not at all a bad result for the hardware; DLSS has its own processing cost that eats into pixel count, which is why a lot of other games like RE Requiem or Pragmata that use this model render at quite low resolutions.

CPU and bandwidth - idTech 7 is bandwidth heavy, from what I understand. Honestly, waiting to see if whoever is porting DOOM Dark Ages manages to make it run at 60fps...even if it's based on something like dynamic 600p. Apparently, idTech 8 is better positioned to achieve that than idTech 7.

With regard to the third party output once the PS6 launches, while I do think ports will become less common when the next gen arrives, by that point Nintendo should be putting out much more first-party titles to compensate. Currently the 3rd-party ports are doing the heavy lifting for the Switch 2 because Nintendo is taking forever to make games for the hardware. But that situation will reverse over time once the first-party games start arriving and making ports becomes more difficult.

With Indiana Jones, my big concern was shadow quality, because shadows really seemed to pop-in close to the player in the prerelease footage.  But while that issue is still there, I find it a lot less noticeable when playing on my 4k tv than it was in 1080p Youtube previews.  Maybe that footage was mostly taken from handheld mode.  It's a beautiful game overall.
