High recording bitrates on specific applications

[genesis69420]

Hi, I am encountering a weird behavior while recording Call of Duty with OBS. While recording CS2 or Helldivers 2 (in 1440p ultra @60fps) is creating files with around 30mbps bitrate, my COD recordings are at 200+mbps.

My encoder settings are as follow :

Encoder : NVIDIA NVENC HEVC
No rescaling
CQP : 20
Preset : P5
Tuning : High Quality
Two passes (Quarter Resolution)

Also OBS priority is high by default and runs as admin

Thank you for your insight

With CQP, bitrate depends on the requested quality. Games with higher graphics detail require more bitrate for the same quality. So if COD is a game that renders with more detailed graphics than the other games, this can be the reason. Foliage, particles, dust and in general sophisticated large scale animations can greatly increase required bitrate.
