Gamers can expect higher frame rates and shorter loading times for these old games without Pro patches. According to reports from those who've had hands-on time with "Boost Mode", the new system setting will only provide a performance increase for games that don't have locked frame rates. Sony had always stated in the past that using extra horsepower on older titles was not possible to ensure 100% compatibility with all games.
Post-release, it was confirmed by sources that the PlayStation 4 Pro base mode would not improve games that did not receive patches.
The update for the PS4 has already been rolled out for firmware beta testers, so keep a look out for an official update on Fenix Bazaar for when a wide rollout is planned.
From this analysis, which you can further check the attached video, on PS4 Pro Action Mode supports a variable resolution, ranging from 1080p to 720p. A spokesperson told the site that, with Boost Mode active, the Pro runs "at a higher GPU and CPU clock speed in order to improve gameplay on some PS4 games that were released before the launch of PS4 Pro".
The PlayStation 4 4.5 firmware update will also introduce external HDD support. At the moment, it remains unclear when Sony will officially launch Firmware 4.50 for the general public.
