Finalmente :asd:
Clicca per espandere...

Io non ce l’ho l’opzione vrr, come mai?

scusate,macome si aggiorna il dualsense?
fa tutto in automatico?
Clicca per espandere...
Quando accendi la console appare un mess che il dualsense ha l'aggiornamento, in quel momento devi collegarlo via cavo e il pulsante "aggiorna" diventa premibile, premi ed in pochi secondi lo aggiorna.
 
 
Ho appena controllato e funziona già, comodissimo. C’è un limite temporale ovviamente, sull’app si trovano solo le catture degli ultimi 14 giorni
 
Ieri sera ho giocato un'oretta e poi ho spento. Stamani riaccendo e mi sta reinstallando e scaricando nuovamente il tutto, è un bug del nuovo aggiornamento? È la prima volta che succede

There are some things to be aware of in relation to VRR, LFC and the PS5 that could be problematic.

First of all, you should know that the PS5 currently only outputs a 120Hz signal if the setting is enabled in the system and a game explicitly enables it. Otherwise, the PS5 only uses a 60Hz signal.

As the PS5 has a HDMI 2.1 bandwidth limit of 32Gbps, a 120Hz mode at a UHD resolution means that a color subsampling of 4:2:2 is used plus a limited range signal - as opposed to an RGB/4:4:4 mode with the free choice of a full/limited range at 60Hz. This can lead to a slightly poorer color representation and, depending on the TV set, also to banding problems.

Furthermore, all screens have a limited VRR range, for example if you have a tv with VRR range of 40-120Hz and the source can't at least deliver a new frame every 25ms (40Hz) it has to use LFC (Low Framerate Compensation) for VRR to be effective, otherwise you'll end up with a tearing effect in case of varying framerates.
For LFC to work at all, however, it is necessary that the upper limit of the VRR range is at least 2.5x as large as the lower limit. I.e. LFC won't be active if your TV is getting a 60Hz signal because the VRR range would be 40-60Hz in this case.

So what does this mean for PS5 games and the upcoming VRR update?

If a game renders with less than 40FPS but the HDMI signal is 60Hz, then VRR cannot be active because it would require LFC to prevent screen tearing effects. The game or the system would have to switch to a 120Hz HDMI signal for LFC to become available, but this leads to the mentioned color subsampling / limited range signal.

If a game has a 60FPS target and the PS5 doesn't switch to a 120Hz signal, the effective VRR range will be 40-60Hz. Which will help compensate occasional drops below the target framerate down to 40FPS but doesn't help if the game could go beyond 60FPS. The latter would again require the PS5 to switch to a 120Hz signal.

So I hope everyone understands that it will be very important for Sony to output a 120Hz signal in VRR mode. Otherwise VRR will have little or no effect on most games.
At the same time, this will also mean that you have to live with the 4:2:2 colour sub-sampling in 120Hz mode.

In any case, game developers must additionally deliver patches that remove the upper framerate limit in order for a game to output more frames. I.e. the usual 30 or 60FPS cap has to be removed. Otherwise, the VRR update will again have little or no effect.
 
Ultima modifica:
Parlando con la chat di Amazon, c'è un team apposito che di occupa della situazione. Ovviamente ne sanno quanto me quelli della chat, ma in compenso mi ha dato un buono da 5€ :happybio:
