serializeRender Black ops 3 Difference in inputlag?

[Kirayamato]

hi guys so black ops 3 just got a new option i want to know how much of a difference in input should you see with this option looks really interesting would really like your guys input thanks


//0 use two threads, one thread update frame N while the second render N-1. 1 concatenate update and render. 2 concatenate update render and frame presentation.
// 0 is the default for the best performance, 1 and 2 improve latency but require a powerful CPU.
SerializeRender = "2" // 0 to 2

If I understand it right, 0 should be used in a CPU limited v-sync off scenario, 1 in a GPU limited v-sync off scenario, and 2 in a v-sync on, monitor limited scenario (provided the framerate hit from that setting doesn't drop you below the refresh rate.)

There are too many variables to say how big a difference it makes on your system unless you test it yourself.

so if my gpu is getting max out and i still have some cpu usage left i should use 1 or 2? for the best latency with vsync off?

How big a difference in framerate is there between each option? I think 1 would be the best option for v-sync off. 2 should have the lowest possible start of frame latency, but it might not have the lowest average latency, if there's a significant drop in framerate.

right now on 1440p 144 hz monitor am dipping below to an average of around 120 on option 2 and option 1 is closer to what 0 is so deciding to run that as 2 might be better but the frame drop is worse
