How to Boost FPS on a Low-End PC (The Ultimate Zero-Lag Guide)

Published by BSR Studios • March 20, 2026

Playing games on a low-end laptop or a PC with only 2GB to 4GB of RAM can be incredibly frustrating. Stuttering screens, massive frame drops during gunfights, and that dreaded 15 FPS slideshow can ruin your entire gaming experience.

But before you give up and assume you need to buy an expensive gaming rig, wait! Windows OS is full of hidden bottlenecks. By applying a few smart, deep-system tweaks, you can force your hardware to push out maximum performance. This guide will show you exactly how to unlock smooth 60FPS gameplay on your potato PC.

1 Enable High Performance Power Plan

By default, Windows sets your PC's power plan to "Balanced" to save electricity and battery life. This heavily restricts your CPU and GPU from reaching their maximum clock speeds during gaming.

  • Press the Windows key, type "Choose a power plan" and press Enter.
  • Click on the dropdown arrow that says "Show additional plans."
  • Select the High Performance option. (If you are on a laptop, make sure your charger is plugged in while gaming to prevent battery drain).

2 Update Your Graphics Drivers

Running games on outdated graphics drivers (like older Intel HD Graphics drivers) is the #1 cause of low FPS and visual glitches. GPU manufacturers constantly release updates specifically to optimize new games.

  • Right-click the Windows Start button and open Device Manager.
  • Expand the Display Adapters section.
  • Right-click your graphics card (Intel, AMD, or NVIDIA) and select Update driver.
  • Choose "Search automatically for drivers." (For the best results, download the official updater software like NVIDIA GeForce Experience or Intel Driver Support Assistant).

3 Turn On Windows Game Mode

Microsoft built a dedicated "Game Mode" into Windows 10 and 11. When activated, it forces Windows to prioritize your game's processing needs and suspends heavy background updates (like Windows Update downloads).

  • Press Windows Key + I to open Settings.
  • Click on the Gaming category.
  • On the left menu, select Game Mode.
  • Toggle the switch to On.

4 Lower In-Game Resolution & Graphics

It might sound obvious, but playing at 1080p on a 2GB RAM system is asking for disaster. Resolution dictates how many pixels your GPU has to draw every second.

  • Open your game's Video/Graphics settings.
  • Change your resolution from 1080p (1920x1080) to 720p (1280x720). This alone can double your FPS.
  • Turn off heavy post-processing effects like Anti-Aliasing (AA), V-Sync, Shadows, and Motion Blur. Set texture quality to Low or Medium.

5 Stop Using Heavy Background Software (OBS)

Gamers with low-end PCs often try to record their gameplay for YouTube using heavy software like OBS Studio or Bandicam. OBS encodes video in real-time, which eats up massive amounts of CPU and causes horrific in-game lag spikes.

  • The Solution: If you want to record 60FPS gameplay without losing a single frame, you must switch to a zero-lag alternative.
  • We highly recommend using Any Screen Recorder by BSR Studios. It captures uncompressed raw data directly from the GPU at just 2% CPU usage. It encodes the video after you stop playing, ensuring your game never lags.

By combining these 5 powerful tweaks, you are freeing up your system's hardware to do what it was meant to do: run your games smoothly. Happy gaming!
