How to Get 144Hz in League of Legends on RTX 5090

Let us be completely honest. If you are dropping serious ZAR on Nvidia's ultimate flagship GPU, playing a decade-old MOBA is like driving a Ferrari in a school zone. Yet, we still see local gamers asking how to get 144Hz in League of Legends on RTX 5090 setups. The short answer is... very easily. The long answer involves optimising your system to prevent screen tearing and wasted power.

Why Capping Your FPS Matters 🚀

An RTX 5090 will push thousands of frames per second in League of Legends. Without a frame cap, your GPU works overtime for absolutely no visual benefit. This generates unnecessary heat. In South Africa, keeping a rig cool during summer is vital for hardware longevity and sustained performance.

You also want to avoid visual tearing. If you are currently browsing the latest graphics cards, you probably know that matching your frame rate to your monitor refresh rate is the golden rule of smooth gameplay. Pushing 800 FPS to a 144Hz monitor just creates stuttering, screen tearing, and annoying visual artifacts.

Step-by-Step Guide to 144Hz Perfection 🔧

First, ensure your monitor actually supports high refresh rates and is plugged in correctly. You can buy the most expensive rig from our best gaming PC deals, but a standard 60Hz screen will only ever show 60 frames. Furthermore, always use a high-quality DisplayPort cable rather than an old HDMI cord... otherwise, you might be artificially locked at lower refresh rates.

1. Right-click your Windows desktop and open the Nvidia Control Panel.
2. Navigate to the 'Change resolution' tab and ensure the refresh rate drop-down is firmly set to 144Hz.
3. Turn on G-Sync if your monitor supports it to eliminate screen tearing completely.
4. Open League of Legends, head into the in-game video settings, and find the 'Frame Rate Cap' option. Set this to exactly 144 FPS.

If you prefer a plug-and-play solution without endless tinkering, checking out our pre-built PC deals ensures you get a system perfectly balanced for your exact display needs straight out of the box.

Do You Really Need a 5090 for LoL? ✨

Absolutely not. While having the absolute pinnacle of hardware is incredible for 4K ray-traced titles, esports games are famously designed to run on almost anything. If your primary focus is simply ranking up in Summoner's Rift, you might find much better value exploring premium notebooks for sale that offer portable 144Hz displays and built-in batteries to survive load-shedding.

However, if you are future-proofing your battle station for the next decade of heavy-duty gaming, the 5090 is an undisputed beast. Just remember to pair it with a 4K or 1440p monitor that actually does the hardware justice. Keep an eye on our weekly tech specials to find premium high-refresh-rate displays that can easily keep up with this monster GPU.
