Black Ops 4 PC Tip: How to Fix High CPU Usage, Low Performance issues

Call of Duty: Black Ops 4 on PC has a small issue where some users not on the highest-end hardware will face high CPU usage and low performance while playing the game. We’ll be going over two methods that will help remedy this issue.

The problem stems with how Black Ops 4 detects processors and handles different CPU threads. Our first fix will probably not fix the problem the whole way but should take strain some load off your CPU.

NVIDIA users should go into NVIDIA Control Panel, then Manage 3D Settings, Program Settings and then Call of Duty: Black Ops 4. Here set the pre-rendered frames to 1 so that the CPU doesn’t waste resources preparing frames for the GPU before they’re ready to be drawn. AMD users should do the same with their driver suite.

Now we’ll be experimenting with the config.ini file, you can find the file in the directory below:

C:\Program Files (x86)\Call of Duty Black Ops 4\players\config.ini

We’ll be focusing on two main settings here, both of which can only be accessed from this config file and not the in-game settings:

worker_threads

threaded_rendering

First you should check and note down what your default numbers were, most users who had the problem had numbers like worker_threads 2 and threaded_rendering 0.

First you need to change the value of threaded_rendering to 1.

After this experiment a bit with the worker_threads settings to see what best suits your processor. The best setting for this game that players report are using one less worker_threads than your PC’s threads. If that doesn’t work, try another value that may better work for your specific processor.

After making the change save your config file and make sure that you’ve applied this setting to make sure it doesn’t get reset on each startup.
