PlayStation 6 backward compatibility will greatly benefit from the existence of the PlayStation 5 Pro, just as the base model benefited from the existence of the PlayStation 4 Pro.
Speaking during their weekly podcast, the tech experts at Digital Foundry clearly highlighted how the existence of the soon-to-be-released mid-generation refresh console is a victory even for those who are not going to buy it.
Much like it was with the base model, backward compatibility benefited greatly from the PlayStation 4 Pro, as not only does the current generation console run previous generation games in Pro mode but also enhances them in certain instances.
Games that have shaky performance on PS4 Pro, for example, run much smoother on the current generation system, while games using dynamic resolution scaling benefit from the increased power of the current system by pushing towards the upper bound of the resolution range.
The same is likely going to happen with the PlayStation 6, considering there's a very good chance some games will still run at 30 FPS on PlayStation 5 Pro, which will likely be bumped up to 60 FPS on the next-generation system.
