Digital Foundry Intensive testing was conducted on PS1 PS2 and PSP games Inside Backwards compatibility offered on PS4 and PS5 With new subscription PS Plus Premium That with conclusions They are not satisfactoryIn this case too.
We have already seen a specific rejection by ElAnalistaDeBits, but in this case the analysis is as in-depth as usual for the digital foundry. However, according to the British column, the backward compatibility of the PS5 and PS4 is “not enough”. The good news is that the used PS1 prototype is not the same as the infamous PlayStation Classic, but it does share a variety of issues.
As for the problem of 50 Hz PAL Used in NTSC games as well, Digital Foundry argues that this solution is not common to all games, but to most people. Oddly enough, all of Sony’s first parties are currently running at 50 Hz. For example, as for the Ape Escape, it has cut shots at 30 fps, with various frame speed control issues, and the game actually has 25 fps.
The Continuous stuttering and frame-rate inconsistency Derived from the need to display the 50 Hz code in the 60 Hz container provided for the PS5, but even selecting the 50 Hz console output did not improve the situation because the general recession is still apparent. Wild Arms, Jumping Flash, Kurushi, Two Worms and Everybody’s Golf are only available at 50 Hz in the PAL version, although the Asian lineup of the PS Plus is eagerly going Deccan 2 and Mr. Thriller. 60 Hz And they are so much better.
For Resolution, PS5 Classic games up to 192×1440, which results in very limited polygons and configurations, but according to Digital Foundry there are problems with sub-pixel accuracy related to the lack of accuracy in floating point operations. As a result, there is one particular contradiction common to PS1 games, with unstable 3D models having an even worse effect with increased resolution.
Options for Filters Incredible compared to other emulators or dedicated retrocomming machines: the default and modern ones are very similar, the latter creates a darker image by increasing contrast, while the retro classic option introduces a scanline filter, even if it is not nice. Unlike the dedicated solutions found on the RetroTink 5x Pro, it does not line up exactly with the effective pixel grid.
Options for thisRatio Raise doubts: The default option works well with Simple 4: 3 inserted in the 16: 9 window, but other options (1: 1 and square pixel) introduce distortions, crushing the image with incorrect scaling. According to the title, these options are included without precisely understanding the effect they should have had.
As for the PSP emulation, 50 Hz is not the problem, but it has other things. In particular, as the resolution is increased from the original 480×272 to 1080p, the 2D components will be filtered and blurred. Also, strangely, the PSP has the same filters as the PS1, which includes the scanlines, which is very strange considering that the original console did not have the LCD screen and CRT, so those lines don’t make sense. The aspect ratio options taken from the PS1 are not included, the original screen was already 16: 9.
As for the PS2 emulation, finally, it is the same as the PS2 classic on the PS5, the resolution is increased and some issues remain unchanged from the emulation seen earlier.
