PlayStation 4 looks like it could be getting a PSone and PS2 support announcement this year, but an industry insider has claimed that Sony's tech is currently coming back with mixed results. Disc-based backwards compatibility could also come to the console.

It follows claims made by reputable industry tipster Ahsan “Thuway” Rasheed, who said that PS4 will soon support some PSone and PS2 classic titles at native 1080p. However, he now claims that the high-end rendering only works with some titles, while others are coming back choppy and unimpressive.

He elaborated on the matter in this string of tweets:

Oh and for those asking about any update about the PS2/PS1 emulation for PS4. I don't know what Sony's plans are concerning disc playback.

What I have heard is the emulation experience ranges from absolutely amazing 1080p to terribly buggy single FPS garbage.

Sony doesn't want to ship a half baked product with people complaining about inaccurate features.

Oh and they are listening for your feedback for the firmware and OS side of things. Please be vocal.

I am legitimately telling you the PS2 emulation is real, if you want local disc playback, make noise. They've made a reputation by listening
