How to Monitor CPU Usage with Msi Afterburner
Man, I remember when I first started tweaking my PC. I thought, ‘I need to see everything!’ So I downloaded every overlay app, every monitoring tool. Ended up with more pop-ups than a bad pop-up ad site. My frame rates tanked, and I still didn’t know what was actually bogging down my system.
Then I stumbled on MSI Afterburner. It felt like a revelation, but even then, I wasted weeks fiddling with settings that didn’t make sense, just blindly following forum advice. It’s not as simple as just hitting a button, which is why figuring out how to monitor CPU usage with MSI Afterburner correctly matters.
Honestly, a lot of the advice out there is garbage. They tell you to track a million things, but what you really need to know is what’s screaming for attention.
That’s where this comes in.
Why Msi Afterburner Is My Go-to for Performance Monitoring
Look, I’ve been around the block with PC hardware. I’ve seen software promise the moon and deliver dust. But MSI Afterburner? It’s the real deal. It’s not just for overclocking, though it’s brilliant at that too. It’s a window into your PC’s soul, telling you exactly what’s happening under the hood in real-time. And when you’re trying to figure out performance hiccups, especially with how demanding modern games and applications can be, knowing your CPU load is paramount. I’ve spent a frustrating $150 on fancier, proprietary monitoring software that was less intuitive and just as effective. That was a hard lesson.
The beauty of Afterburner is its flexibility. You can configure it to show you exactly what you need, and crucially, only what you need. This means you’re not staring at a cluttered screen while trying to pull off a clutch play or render a complex scene. The on-screen display (OSD) is the key here; it overlays vital information directly onto your application, be it a game, a video editor, or anything else demanding.
Setting Up the Basics: Getting Afterburner Ready
First things first, you’ve got to download it. Head over to the official MSI website. Don’t grab it from some sketchy third-party download site; you’ll just end up with malware or an outdated version. Install it – it usually comes bundled with RivaTuner Statistics Server (RTSS), which is what actually handles the on-screen display. You need both. When you fire up Afterburner, it might look a bit intimidating with all the sliders and graphs. Don’t sweat it. We’re focusing on monitoring, not turning your GPU into a rocket ship just yet.
The main window shows your GPU temp, clock speeds, and fan speed, which is useful. But for CPU monitoring, we need to tweak the settings. Click that little cogwheel icon – the settings button. This is where the magic happens. (See Also: How To Put 144hz Monitor At 144hz )
Core Monitoring Tweaks
Navigate to the ‘Monitoring’ tab. This is the heart of our operation. You’ll see a long list of hardware parameters. We’re interested in CPU usage, but not just the overall figure. You need to see per-core usage. Find ‘CPU usage’ in the list. Click on it, and then below, check the box that says ‘Show in On-Screen Display’. Immediately below that, you’ll see ‘GPU usage’. We’ll get to that, but for now, focus on CPU.
Now, scroll down further. You’ll find entries like ‘CPU1 usage’, ‘CPU2 usage’, and so on, up to however many cores your processor has. For each one you want to track, you *must* check ‘Show in On-Screen Display’. This is tedious, I know. It feels like you’re manually ticking boxes for an eternity, especially if you have a 16-core beast. It took me about fifteen minutes the first time I did it on my old i7.
Crucially, for each of these CPU core entries, you also want to select ‘Show in On-Screen Display’ and crucially, assign a ‘Graph window’ to each. This is what creates the visual representation. You can assign them all to the same graph window, or give them separate ones. Giving each core its own graph window helps immensely when you’re trying to identify a specific core that’s hitting 100% and bottlenecking everything else. The fan noise in my old rig used to ramp up like a jet engine whenever one core was maxed out while others idled, and seeing that visual cue was a lifesaver.
Rtss Configuration for the Overlay
Once you’ve told Afterburner what to show, you need to tell RTSS *how* to show it. Close the Afterburner settings and look for the RTSS icon in your system tray – it’s usually a red shield. Click on it. You’ll see a cleaner interface. Under ‘On-Screen Display’, you can adjust things like the text color, size, and position. This is where you can make sure the data isn’t obscuring your game or application.
This part felt like I was learning a foreign language at first. All these settings for refresh rates and color codes. It’s not rocket science, but it requires patience. I once spent an entire evening trying to get the CPU usage text to be a specific shade of neon green. That was… a suboptimal use of time, but it taught me how to fine-tune the overlay to my exact preferences.
You can add specific items to the display here, or you can rely on Afterburner’s settings. For CPU monitoring, Afterburner’s setup is usually sufficient, but RTSS gives you the fine-tuning control over the aesthetic. Make sure ‘Show On-Screen Display’ is enabled in RTSS.
What to Actually Look for: Reading the Data
So, you’ve got the overlay running. What are you looking for? Simple: spikes and sustained high usage. If your overall CPU usage is consistently hitting 90-100% during a game or task that shouldn’t be that demanding, you’ve found your bottleneck. This is where the per-core monitoring shines. You might see one or two cores pegged at 100% while others are loafing around 20-30%. This indicates a specific application or game thread is not optimized to use all your CPU cores effectively.

This is incredibly common with older games or poorly coded applications. It’s like having a team of ten workers, but only two of them are actually doing anything, and they’re drowning in tasks. The other eight are just standing around. It’s infuriating because your powerful CPU isn’t being fully utilized. I remember playing a game years ago that would stutter like crazy, and my monitoring showed one core at 100% while the rest were barely ticking over. Turns out, that game was notoriously single-threaded.
Contrarian Take: Not Every Core Needs to Be at 100%
Everyone talks about keeping CPU usage low. I disagree. When you are running something demanding, like a complex simulation or a AAA game, you *want* your CPU to work hard. The goal isn’t to keep usage at 30%. The goal is to see if the *demand* is exceeding the *capacity*. If your CPU usage is at 100% across all cores, and your performance is still excellent, that’s a good thing! It means you’re getting your money’s worth out of your processor. It’s when you see 100% on one or two cores and a massive performance drop that you have a problem. Don’t panic just because the numbers are high; panic when the *experience* is bad and the numbers tell you *why*.
Comparing CPU Usage to GPU Usage
This is where it gets really interesting. You need to monitor both your CPU usage and your GPU usage. If your CPU usage is maxed out (say, 95-100% across most cores) but your GPU usage is low (like 40-60%), your CPU is the bottleneck. It’s working as hard as it can and can’t feed enough data to the GPU to keep it busy. This is often called a ‘CPU bottleneck’.
Conversely, if your GPU usage is consistently at 95-100% and your CPU usage is significantly lower, your GPU is the bottleneck. This is generally the preferred scenario for gaming, as GPUs are typically the primary drivers of graphical performance. It means your CPU is doing its job and feeding the GPU data fast enough for it to be fully utilized. It’s like a well-oiled machine, with the CPU as the efficient foreman and the GPU as the powerhouse factory worker.
| CPU Usage | GPU Usage | Likely Bottleneck | My Verdict |
|---|---|---|---|
| 90-100% | < 60% | CPU | Something’s holding your CPU back. Check per-core usage for uneven loads. |
| < 60% | 90-100% | GPU | This is ideal for gaming. Your GPU is working hard, driving performance. |
| 80-90% | 80-90% | Balanced | A good balance, though a slight GPU-bound situation is often preferred. |
| < 50% | < 50% | System Idle / Underload | You’re likely not pushing the system hard enough or have background processes interfering. |
Troubleshooting Common CPU Usage Issues
If you’re seeing consistently high CPU usage, especially on specific cores, what can you do? First, close unnecessary background applications. Seriously, that browser with 50 tabs open might be hogging resources. Check your Task Manager (Ctrl+Shift+Esc) to see what’s eating CPU cycles. Sometimes, a specific game or application has a known issue or a setting that causes it to hammer the CPU.
In some cases, you might need to limit the frame rate. Some games try to render as many frames as humanly possible, and if your CPU can’t keep up with that demand, it’ll stutter. Limiting the FPS (often through game settings or GPU control panel) can smooth things out and prevent a single core from being overloaded. It’s counter-intuitive, like telling a sprinter to run slower, but it makes the overall race smoother. I learned this the hard way trying to push for 240 FPS in a game that only benefited up to 140 FPS with my specific CPU.
When to Consider an Upgrade
If, after all this tweaking, you’re still seeing your CPU pegged at 100% in the applications you care about, and your GPU is consistently underutilized, it might be time to consider a CPU upgrade. There’s a point where software optimization can only do so much. According to organizations like Puget Systems, which does extensive professional workstation benchmarking, CPU architecture and core count are increasingly important for demanding professional applications and high-refresh-rate gaming. Pushing beyond the capabilities of your current processor means throwing good money after bad trying to optimize it further. (See Also: How To Monitor My Sleep With Apple Watch )
What Is Considered High CPU Usage?
Generally, sustained CPU usage above 85-90% on most cores while performing a task that isn’t exceptionally demanding (like running a simple application or a less intensive game) is considered high. For very demanding tasks like rendering video, compiling code, or playing the latest AAA games, usage can and often should be higher, sometimes reaching 100% on all cores if the software is well-optimized. The key is whether this high usage leads to performance degradation.
Can Msi Afterburner Monitor All CPU Cores?
Yes, MSI Afterburner, in conjunction with RivaTuner Statistics Server, can monitor and display the usage for each individual CPU core (e.g., CPU1, CPU2, CPU3, etc.). You just need to go into the Afterburner settings under the ‘Monitoring’ tab, find the individual CPU core usage entries, and enable ‘Show in On-Screen Display’ for each one you wish to track.
Why Is My CPU Usage at 100% in a Game?
This usually means your CPU is the bottleneck. The game is demanding more processing power than your CPU can provide in real-time. This could be due to the game itself being CPU-intensive, poor optimization for multi-core processors, too many background applications running, or simply an older/less powerful CPU struggling with modern demands. Check per-core usage to see if one or two cores are overloaded while others are not.
How Does CPU Usage Affect My Pc’s Performance?
High CPU usage directly impacts performance by limiting how quickly your computer can process instructions. If your CPU is maxed out, it can’t handle new commands or tasks efficiently, leading to dropped frames in games, stuttering, slow application loading times, unresponsiveness, and overall sluggishness. It can also cause system instability and overheating if the CPU is pushed to its absolute limit for extended periods.
Should I Always Show CPU Usage in My Game Overlay?
Not necessarily. While it’s incredibly useful for troubleshooting performance issues, constantly staring at CPU usage numbers can be distracting and detract from your gaming experience. It’s best to enable it when you’re experiencing problems or testing new settings, and disable it for regular gameplay if you find it intrusive. You can quickly toggle the OSD on and off via a hotkey in RTSS if you set one up.
Final Thoughts
So, there you have it. Figuring out how to monitor CPU usage with MSI Afterburner isn’t just about seeing numbers; it’s about understanding what those numbers mean for your actual experience. Don’t get lost in the weeds with every single statistic; focus on CPU load, especially per-core, and compare it to your GPU’s workload.
My own journey through this involved a lot of trial and error, particularly when I was trying to diagnose stuttering issues in games that I initially blamed on my graphics card. It turned out my older CPU was the real culprit, unable to keep up with the demands of modern titles, even when my GPU was practically idling.
If you’re still scratching your head after checking your usage, go back to the basics: close background apps, check your task manager for anything unusual, and consider if the software you’re running is just too demanding for your current hardware. Sometimes, the most complex problems have surprisingly simple root causes, and seeing that CPU usage spike is your first clue.
The next time your PC feels sluggish, fire up Afterburner, enable those per-core stats, and see what your processor is really doing. You might be surprised.
