Best FPS Booster Software for Low-End PCs

Here are the top options, each offering unique benefits for gamers on a budget or with older machines:

Razer Cortex: Game Booster

Free, user-friendly, and effective for most low-end setups. Razer Cortex suspends unnecessary background apps, cleans RAM, and offers one-click optimization. Many users report a 10–15% FPS boost in popular games like Valorant and Fortnite. It also features an FPS overlay and basic benchmarking tools.

Wise Game Booster

Another free tool, Wise Game Booster lets you manually close background processes and optimize system settings. It’s lightweight, easy to use, and especially helpful for squeezing extra performance out of limited hardware. FPS gains are modest but noticeable, particularly if background tasks bog down your PC.

Hone

Hone offers both free and premium plans. The free version includes 10 one-click optimizations, a PC cleaner, and essential game tweaks. Premium unlocks unlimited system tweaks, BIOS optimization, and pro settings. Hone is praised for measurable FPS improvements and reducing system lag, with real-time optimization routines designed for gaming stability.

Glary Utilities PRO

Known for its one-click Game Booster, RAM cleaner, and disk cleanup tools. It helps free up memory and reduce clutter, leading to smoother gameplay and faster load times. 

Avast Cleanup Premium

Features a dedicated Game Mode that pauses background tasks and updates, freeing up CPU and RAM for optimal gaming performance. 

BoosterX

Designed for Windows, BoosterX increases FPS, reduces input lag, and eliminates freezes or stutters. It’s another good choice for low-end systems needing a quick, automated boost.

WTFast

Sometimes, low FPS and stuttering aren’t just about your hardware or system load. Network issues, such as high ping and packet loss, can cause stutters and lag spikes. That’s where WTFast comes in. Combining system boosters with WTFast’s network optimization can give you the best overall gaming experience on a low-end PC.
