The PC version of Blackout, Call of Duty: Black Ops 4's battle royale mode, will be capped at 120fps at launch.
This capped framerate will help reduce the load on servers, developer Treyarch explained, the idea being the moment the game launches it has a high stability for every player.
"Since the framerate affects the load on the servers, we want to ensure that the game delivers a great playable experience for everyone who dives in those first moments," the developer said in a post on r/Blackops4.
However, as soon as the servers are stable, the framerate cap will be raised to 144fps. And then, all being well, within the first few days of launch Treyarch will enable uncapped framerates for Blackout.
"This is the right plan to ensure a smooth, playable game for the whole community out of the gate," Treyarch added.
It's worth noting zombies and other multiplayer modes will be uncapped on day one, 12th October.
Treyarch is working with fellow Activision-owned studio Beenox on the PC version of Black Ops 4. The developers have promised it's not a port - rather development of the PC version was worked on simultaneously alongside the console versions.
