Renderer Worker Count Finder for Call of Duty
Type your CPU name, select it from the list, and this tool will show a recommended RendererWorkerCount value based on HD OPTI tuning – aimed at FPS boost, smoother 1% lows and lower latency in Warzone, MWII, MWIII, BO6 and BO7.
Find Your Recommended RendererWorkerCount
If your CPU isn’t listed, follow the general PC optimisation rule from the main guide: Intel hybrid chips ≈ P-cores − 1, AMD/non-hybrid ≈ physical cores (or cores − 1 on very high core counts) for balanced FPS and latency.
How to Find Your Exact CPU Name in Task Manager
To get the most accurate RendererWorkerCount recommendation and avoid typos, copy your CPU name straight from Windows. This is a simple PC optimisation step that helps ensure you pick the correct preset.
- Press Ctrl + Shift + Esc to open Task Manager.
- Click the Performance tab.
- Select CPU on the left.
- At the top-right of the graph, you’ll see the full CPU name (for example
13th Gen Intel(R) Core(TM) i7-13700KForAMD Ryzen 7 5800X3D 8-Core Processor). - Enter your CPU name into the search box above.
Why Renderer Worker Count Matters for FPS & Latency
Renderer Worker Count tells Call of Duty how many CPU threads to dedicate to rendering frames. If this number is too low, your GPU can sit idle, wasting performance and leaving FPS boost on the table. If it’s too high, Windows and background tasks fight for CPU time, causing stutters, hitching and higher input latency.
By tuning this value for your exact processor, you’re effectively doing targeted PC optimisation for Call of Duty’s engine. The goal is to find the sweet spot where:
- Your average FPS improves or stays high.
- 1% and 0.1% lows rise, reducing spikes and drops.
- Frame times become more consistent, which translates directly into lower latency and a smoother aiming feel.
- Your CPU doesn’t slam at 100% on all cores, which helps stability.
This isn’t a magic overclock, but when combined with good RAM, GPU settings and background app control, it’s a reliable FPS boost and latency optimisation for competitive play in Warzone, Ranked and other CoD titles.
How to Apply This in Your Config
Once you have your number, open your Call of Duty config (for example adv_options.ini, options.ini or COD HQ config) and set:
RendererWorkerCount = <your number here>
Save the file, then optionally mark it as read-only to stop the game from overwriting the tweak. If you see crashes, CPU spikes or extra stutter, lower the value slightly or remove read-only. Every rig is different, so treat this as a safe starting point for your own PC optimisation workflow.

FAQ
Not always, but it often improves 1% and 0.1% lows, which makes the game feel smoother even if the maximum FPS number doesn't skyrocket. The goal is consistent FPS and lower latency, not just a big peak value in a benchmark.
Yes. You're not overvolting or overclocking the CPU – just telling the game how many worker threads to use. If performance or stability feels worse, simply revert the change or drop the value by 1. It's a reversible PC optimisation tweak.
It can't fix bad routing or network issues, but by smoothing CPU usage and frame times it often reduces perceived input delay. For the best latency, combine this tweak with good in-game settings, disabled overlays, and a clean background environment.
Pair this with a sensible FPS cap, tuned graphics settings, clean RAM usage, and background app control (Discord, browsers, overlays). Together these form a complete PC optimisation stack that gives you a much more stable FPS boost in sweaty lobbies.
