There is something wrong with the backward compatibility of PlayStation 5 And 4 with the games of the era PS1, PS2 And PSP introduced in these last two generations by the library of classic titles included in the top-tier subscription of Sony: PlayStation Plus Premium. The games, carefully examined by many industry experts, resulted in poor optimization conditions.
The backward compatibility of the PlayStation 5 / e leaves a lot to be desired, and you don’t need to be an expert to say it:
The first decidedly negative opinion came a few days ago from ElAnalistaDeBits, a page expert in technical analysis which, however, has only superficially examined the performance of the console – and that is already enough to call it a disaster without a shadow of doubt. Now, to aggravate the situation, comes the much more in-depth analysis of another group of technical analysis experts: Digital Foundry. According to them the backward compatibility function “It’s not good enough” – The only positive note comes from the fact that the emulator used for games PlayStation 1 it is not the same exploited by the disastrous PlayStation Classic. The new emulator is far more advanced, but unfortunately it shares many problems with its predecessor.
Many have also complained about the forcing of 5th Hz PAL also imposed in games of nature NTSCsolution that Digital Foundry highlights not being in common between all games but, unfortunately, in most cases, yes. Curious fact: at the moment all the first party titles are anchored to 50 Hz. A good example is the beloved Ape Escapea real cult game at the time, which in backward compatibility offers cutscenes at 30 FPS (but with obvious frame pacing problems) while the gameplay runs at only 25 frames per second.
The backward compatibility experience of PlayStation Plus Premium it is plagued by a continuous stutter aggravated by an erratic and wobbly frame rate that derives from the forced display of a code developed at 50 Hz on systems designed for 60 Hz. Unfortunately even changing the console settings to meet this frequency is completely useless, since the slowdowns do not benefit in any way. Other games scourged by nature exclusively PAL 50 Hz I am Everybody’s Gold, Wild Arms, Kurushi, Jumping Flash and the two Worms from Team 17. Curiously, some games like Tekken 2 And Mr Driller they are at 60 Hz, and the yield is much better although far from perfect.
There is also a problem that arises from a feature aimed at improving the quality of games: up PlayStation 5 classic titles undergo an upscale to 1920 × 1440, encountering 2K resolution readjusted to a 4: 3 format. This gives a definition never seen before to textures and polygonal models, however it makes the defects of the sub-pixel more evident, ruined by the lack of precision in floating point operations. All of this, of course, translates into obviously ugly models to look at, which would have performed better without upscale.
The system also presents problems with filters, generally not very convincing, and with the aspect ratio options which, apart from the 4: 3 forced into 16: 9 by default, for the rest of the options results in strong image distortions. . Games PSP, although freed from the 50 Hz problem, they are weak for many other reasons, starting with the excessive upscale which, bringing games from the resolution of 480 × 272 to that of 1920 × 1080, returns visibly filtered and badly blurred images. The emulation of games PS2 is the same as seen in PlayStation 2 Classic on PlayStation 5and it is the one that comes out best of all, with increased resolution to only some problems still unresolved.
Unfortunately, the introduction of several patches by Sonyaimed at solving problems with some of the classic titles of the era PS1 (the most troubled by problems, ed). The patches aimed to force the frequency increase to 60Hz using the technique blending frames, unfortunately, however, the effect obtained generates a series of decidedly uncomfortable graphic artifacts. The frame rate is improved, but the defects that take its place are just as annoying, as you can judge for yourself in the images presented below.
