Yo, what’s up fellow Rainbow Six Siege players! Are you struggling with major lag, stuttering, and freezes while playing your favorite tactical shooter? Well, you’ve come to the right place. In this guide, I’m gonna walk you through some sweet fixes to get rid of that nasty high CPU usage bogging down your gaming experience.
See, Rainbow Six Siege is a beast of a game that really pushes your CPU to the limit. All those destructible environments, particle effects, and physics calculations take some serious processing power. So it’s no surprise that lots of players run into sky-high CPU usage, even on powerful rigs.
But don’t worry, you don’t need to dish out more cash for a beefier processor (at least not yet). There are some simple tweaks you can try to tame that CPU hog and get buttery smooth gameplay back. Let’s dive in!
Keep Your Frame Rate in Check
One of the biggest culprits behind 100% CPU usage in Rainbow Six Siege is uncapped frame rates. You see, the more frames per second your GPU spits out, the harder your CPU has to work to keep up. It’s like a fast donut machine overwhelming the lone donut fryer.
Capping your FPS essentially tells your GPU to slow its roll and lighten the load on your CPU. Here’s how to set an FPS limit:
- Open up Documents\My Games\Rainbow Six – Siege\GameSettings.ini
- Under
[DISPLAY], add a new line:FPSLimit=60 - Save the file and boom, you’ve got a frame rate cap in place.
I’d suggest capping around 60-120 FPS depending on your monitor’s refresh rate. This single tweak could lower your CPU usage from constant 100% down to 60-70% or less. What a difference!
Terminate Background Apps
You’d be amazed at how many programs are secretly running behind the scenes on your PC, gradually nibbling away at valuable CPU cycles. When you fire up an intensive game like Rainbow Six Siege, those background apps can really start to choke your CPU.
Alt-tab out and open up Task Manager. Go to the Processes tab and inspect what’s running. Spotify, Discord, RGB lighting software – they can all potentially contribute to high processor load. Terminate any non-essential apps and you might see a nice drop in usage.
This is especially important for gamers running dual monitors. All those extra desktops and apps on your second display still consume CPU resources! Close down any apps you won’t need while gaming to free up processing power.
Update Those Drivers
Outdated graphics drivers are a common source of game conflicts and performance issues. So make sure you’ve got the latest drivers installed from NVIDIA or AMD. Drivers undergo constant optimizations for the latest games, so keeping them updated is like a free CPU optimization!
To update drivers:
- NVIDIA – Open GeForce Experience and click “Check for Updates”
- AMD – Visit amd.com/en/support and download the latest drivers
After updating, reboot your PC and see if it helps lower your CPU load. Remember to keep drivers updated regularly!
Turn Down Graphics Settings
Higher graphics settings don’t just demand more from your GPU – they require extra processing power from your CPU too. So turning down some settings can actually give your CPU some breathing room and lower usage.
Experiment with lowering settings like Shadows, Lighting, Effects, Anti-Aliasing and Textures. Keep lowering until you find the sweet spot of good visuals and acceptable processor load. You can also try resolution – 1280×720 won’t stress your components nearly as much as 1920×1080.
Disable Overlays
Lots of gamers use overlays for Discord, Nvidia, MSI Afterburner and more. But extra overlays mean extra strain on your CPU. Try temporarily disabling any overlays you don’t absolutely need and see if it makes a difference.
To disable the Nvidia overlay, open the GeForce Experience settings and uncheck “In-Game Overlay”. For Discord, head to User Settings > Overlay and toggle it off. Disable any other overlays churning away in the background as well.
Reinstall the Game
This might seem like overkill, but believe it or not a corrupted game install can sometimes cause absurdly high CPU usage for no apparent reason. Reinstalling cleans out any corrupted, buggy files that could be bogging down your CPU.
Uninstall Rainbow Six Siege through Steam or Uplay, then redownload a fresh copy. Make sure to manually delete any leftover files in the game directory. With a clean slate reinstalled, cross your fingers for lower CPU usage.
Update Windows and Drivers
An outdated Windows installation or hardware drivers can wreak havoc with game performance and cause high CPU usage headaches. So it’s critical to keep Windows, your BIOS, chipset, and other drivers updated.
For Windows, head to Settings > Update & Security and click Check for Updates. For other drivers, visit your motherboard manufacturer’s website and download the latest versions. And don’t neglect your BIOS either – an updated BIOS improves system stability and performance.
Staying updated ensures compatibility and removes the possibility of conflicts tanking your CPU performance. Set Windows to automatically install updates for a hassle-free experience.
Clean Install Windows
If you’ve tried absolutely everything else with no success, a clean install of Windows may be your last resort. A clean install can wipe out any lingering software conflicts and driver issues that are potentially causing problems.
Make sure to fully backup any personal files first! Then boot into the Windows installer, choose “Custom Install” and wipe your drive completely clean before installing Windows anew. Download all the latest drivers, updates, and game files.
Yes, this is a bit extreme and time consuming. But when all else fails, a Windows clean install gives you the best shot at banishing CPU usage gremlins.
Time For a CPU Upgrade?
Despite your best efforts, an aging or lower tier CPU may simply not be up to the task of running Rainbow Six Siege smoothly. CPUs requirements have increased over time as the game became more complex.
If your CPU usage remains worryingly high even after trying all the above fixes, it may be time to upgrade your processor.
For an affordable option, Intel’s Core i5-12400F provides great value and easily handles Rainbow Six Siege. If you’ve got a bigger budget, go for the beefier Core i7-12700K or AMD Ryzen 7 5800X for max performance. Just pop a new CPU into your motherboard and you’ll be all set to frag at high frame rates!
Fixing High CPU Usage – A Recap
Alright, let’s recap all the tips we covered to get Rainbow Six Siege running smooth and keep your CPU usage in check:
- Cap your FPS to 60-120
- Close background apps
- Update graphics drivers
- Lower in-game settings
- Disable overlays
- Reinstall the game
- Update Windows, chipset, and BIOS
- Clean install Windows
- Upgrade your CPU
Try each fix one by one until you pinpoint the specific issue eating up your CPU cycles. With some testing and troubleshooting, you should be able to get usage down to acceptable levels.
No more nasty lag and choppy gameplay ruining your Rainbow Six sessions. Just silky smooth frames and carefree fragging thanks to optimized CPU performance. Now get out there and go secure the room (after implementing some of these fixes of course!)
FAQ
Got some burning questions about resolving CPU usage problems? I’ve got you covered with some FAQs:
Q: Will setting FPS limit to 30 fix CPU usage?
A: Generally not recommended. 30 FPS will feel very choppy and make the game hard to play smoothly. Try limiting to 60-120 FPS for best results.
Q: Does resolution affect CPU usage?
A: Yes, higher resolutions require more CPU power to process, so lowering resolution can potentially reduce CPU load.
Q: Will upgrading RAM help with CPU usage?
A: Upgrading RAM can help in some cases, but the CPU is the main factor for usage issues. Focus on CPU optimization first before upgrading RAM.
Q: Is 100% CPU usage while gaming normal?
A: No, 100% usage during gaming is usually indicative of a problem. Acceptable usage is typically 50-70% for smooth gaming.
Q: How can I monitor CPU usage while gaming?
A: Open Task Manager, go to the Performance tab, and keep it open during gameplay to monitor CPU usage in real-time.
In Closing
Phew, that was a boatload of tips for fixing Rainbow Six Siege CPU usage problems! With any luck, those tricks should have you primed and ready for tackling terrorists without excess lag cramping your style.
