You presume too much.

You can't just take some random games and presume they represent every other game. 3.3 GBs is getting small even for indie games of today, and is clearly in different league compared to 100 GB AAA monster sold today, for PS4 and Xbox One, so I'm not sure what you are trying to prove here.

I fully agree that on average, current games don't optimize loading times particularly well, especially on PC. For an example of AAA game that has horrible loading times (with todays NVME SSDs and CPUs) try Mass Effect 2. Then compare it to Mass Effect 3, which is much better. There's no clear reason why loading times for those very similar games differ at all.

I also fully expect loading times of average games to remaing less than stellarly optimized. Even more so if MS decides to stay on HDD with their next console (are they even in any hurry after Xbox One X?). Is that a reason why Sony shouldn't offer an SSD at all? Not offer NVME SSD? How much would going with SATA SDD save them?

In Trine 4 (not yet published), game install size is currently about 13 GBs and we load somewhere around 3-4 GBs of textures on level change (for full resolution textures). The full loaded-once-done amount is around 4-5 GBs. They are streamed in (actual, CPU limited level loading is typically few tenths of a second), and we don't yet have the special code to do initial loading fast. We also don't have any intelligence in checking which textures could remain in memory between levels (there would need to be a defragmentation step), but some (about one GB as seen in above numbers) are always resident.

Just going with the 4 GB figure and SATA3 speed means eight seconds loading. And this is Trine 4. Most people categorize it as "indie game".

Of course, on PS4 and every other current generation console (including Xbox One X) the texture size will be reduced. On PS5? Well, quite a bit of specs are still missing, so we'll wait and see (or don't see, if the game is never ported).

Hmm? 4k texture pack just means textures that are better than what is enough for some lesser resolution. There's no absolute value for goodness. If resolution X is just right for HD, then 4k will need something more than X. It isn't necessarily 4X, but it's clearly something more.

Unless your point is that 4k is idiotic in general and every sane person should just play in HD. I don't own any 4k screen myself, and only spent significant time with one in my previous job, so I'd rather not argue about that.

> BTW try to find any AAA title that does not splash going to main menu.

There are rarely splash screens during level changes and never while streaming during play.

Also, many games today show splash screens, intro video etc. while doing initial loading. If you skip them, you just wait in loading screen (or main menu) a bit longer.
