PS5 can play all PS5 titles
PS5 can play over 4000 PS4 titles
PS5 can play around 100 of the top PS4 titles in boost mode, which give higher perfomance and better resolution textures.
Sony plans to increase that 100 figure over time.
Is this a correct summary?
No. Corrections as I understand them:
PS5 can play "the overwhelming majority" of over 4000 PS4 titles
PS5 should play any BC title in boost mode, but thousands remain to test...
...and boost will give better framerate and render resolution, up to the maximum the game already allowed
The figure should increase over time, but some games may require original developer input
Of that I was not aware. Appreciate the information. Furthermore, should Sony start a pilot program for their version of "Enhanced BC" then that data can be consolidated into the webpage as well.
Depends what you mean by "enhanced". If that's referring to games that have been patched to take better advantage of the hardware, then definitely there should be an online list maintained. Microsoft does this, but Sony's version is much less detailed and complete.
If you mean the benefits brought to unpatched games when run on the new hardware, I don't think it's reasonable to expect this. Neither platform holder does this right now, and the sheer amount of testing, maintenance, etc. necessary is clearly why.
Off topic: I am interested to learn your thoughts on the PS5 specs revealed thus far. If you have already expressed it elsewhere before, could you kindly pm me a link? Thank you.
I've put bits and pieces in a couple posts, but no summary. Here's a quick one, to not derail: XSX is more powerful than PS5, and that will be detectable in how games run and look. But both PS5's raw performance and its very precise hardware tweaks mean the gap will be small. Plus the overall higher res and more post-processed image of modern games will make the visible differences even less obvious than that. The rendering discrepancy will be there, but sometimes only trained viewers or close examination of still images will make it clear.
