Following PlayStation 4 Pro’s announcement in September, Naughty Dog said multiplayer games will have the same frame-rate on PS4 and PS4 Pro. In the PS4 Pro FAQ from Sony, they were a little less definitive, saying Pro owners “generally” won’t have a performance advantage in online games:
Generally, no. Playtesting and balancing is up to each game developer, and while it?s true that PS4 Pro?s more powerful hardware can drive smoother or more stable frame rates in supported titles, developers have many tools and processes they can use to prevent imbalances.
In Digital Foundry’s PS4 vs PS4 Pro test, they discovered that Battlefield 1’s multiplayer on PS4 Pro “offers a tangible performance advantage over standard PS4 owners.” According to their findings, PS4 Pro gives players up to a 47% frame-rate advantage “in scenarios where the Frostbite engine is under the greatest stress,” most notably 64-player matches. Using two copies of the game played side-by-side on PS4 Pro and PS4 in the same session, Digital Foundry found that PS4 Pro offers up to a 10-15fps advantage over PS4. For example, when the PS4 version hits 32fps, the PS4 Pro version is at 47fps. Additionally, the Pro version stays at the target 60fps more consistently.
They add:
Also interesting is more consistency in frame-times for Pro owners. Battlefield 1 is v-synced, meaning that the target frame-time is 16.7ms – 60 frames per second. However, per...
