What To Expect From The PlayStation 4 Pro new " boost mode ".

The PlayStation 4 Pro new " boost mode " will be coming soon in the 4.5 system software upgrade, and Eurogamer who had the chance test it out. Check video below!

Eurogamer test new mode - available beta users - says the boost mode has a limitation in-game frame-rates  of a 30fps or 60fps cap. However, some games like Killzone Shadow Fall can run with an unlocked frame-rate, but v-sync still dictates an eventual 60fps cap.

Eurogamer also said the boost mode will work best in stabilising performance closer to target frame-rates and should prove interesting on unlocked titles, but you can't expect game-changing miracles.

"Boost Mode has been designed to provide better performance for those legacy titles that have not been patched to take advantage of the PS4 Pro's faster CPU and its faster and double-sized GPU," Sony says. "This can provide a noticeable frame-rate boost to some games with variable frame-rate, and can provide frame-rate stability for games that are programmed to run at 30Hz or 60Hz.

"Depending on the game, the increased CPU speed may also result in shorter load times. Boost Mode is not guaranteed to work with all titles, however, turning the setting off will allow the game to be played in a mode that replicates the standard PS4. As an aside, the older unpatched titles that run in Boost Mode are unaware that they are running on a PS4 Pro and consequently don't take full advantage of the PS4 Pro capabilities; power consumption for these games will therefore be a bit lower compared to playing a newer title."
