That's the thing. If the idea behind PS4 Pro as compared to base PS4 is the following:
1) Better framerate
2) Better image quality
3) Both of the above
Then it really shouldn't be complicated. In the case of Fallout 4 the Pro patch accomplishes #3 on the list, yet people are up in arms due to a ridiculous comparison against boost mode (a beta feature that isn't even rolled out to everyone). I don't think it was ever intended to compare Pro against Pro in that regard.
The question should be are you getting a better experience on Pro than you are on base PS4. That is a resounding "Yes!".
They get higher performance than a base PS4. How hard is that to understand?
Well yeah, people are comparing boost mode to pro mode, even though they use the same resources in different ways, and claiming devs are incompetent for not prioritizing what they specifically want prioritized even if its better than base PS4.
That's my entire issue. There should be no arguments because devs should be free to make pro modes how they feel they should, and boost mode was never intended to compete with pro mode in that way.
With boost mode, the most i could see is Sony relaxing the mandate for new games to have pro patches, if devs feel performance will be better just using system resources(and the game is already 1080p) and they were going to prioritize performance anyway.
I think that's what KH 0.2 and a few others do as well albeit with the FPS uncapped.
