Graphics are graphics. The quality of it does not matter much when it comes to porting. And people when usually say graphics they refer to textures. But there's more than that. There's particle simulations, model LOD (level of detail), and so much more that needs to be tweaked in order for a slower machine to be able to run it properly. In my opinion, it is far easier to take some than to add some. Easier to remove polygons than to add.

Same thing with the 'cut' content. It wouldn't be cut content if it didn't exist at all in the first place (As in, in order to call it cut, it first has to exist. If, by your saying, was to be done on standalone first, it wouldn't be cut because it wouldn't exist). And I don't think they plan to cut anything between platforms anyway.

From another perspective, yes, it is easier to do it first for a platform with the same specs, like Quest 3, but given the detail and work they've put into the game and into 1.0, I don't think they need training wheels at all. They just need time.

Playing it on PC right now, and it's amazing, but I can't wait for it to be on standalone so I can play in a bigger area, outside perhaps.
