Why is my Roblox FPS running so low?

TL;DR

Low Roblox FPS usually stems from high graphics settings, background programs consuming resources, outdated drivers, or power saving mode throttling performance.

Graphics Settings Are Too High

The most common culprit behind low Roblox FPS is having your graphics quality set too high for your system. Open Roblox Studio or join any game, then press Shift + F5 to open the performance stats. If you see your graphics quality is set to 8-10 but your FPS is struggling, manually lower it to 3-5 in the game settings menu.

Background Programs Eating Your Resources

Discord, Chrome with multiple tabs, streaming software, and other games running simultaneously can severely impact Roblox performance. Close unnecessary applications through Task Manager (Ctrl + Shift + Esc) and check which programs are using the most CPU and memory. Even seemingly innocent programs like Spotify or file sync services can cause frame drops.

Outdated or Incorrect Graphics Drivers

Your GPU drivers might be outdated or Windows might be using integrated graphics instead of your dedicated graphics card. Update your graphics drivers through Device Manager or download them directly from NVIDIA, AMD, or Intel websites. For laptops, ensure Roblox is set to use your high-performance GPU in Windows Graphics Settings.

Windows Power Settings

If your computer is set to power saving mode, it will throttle performance to conserve battery. Navigate to Control Panel > Power Options and switch to High Performance or Balanced mode. For laptops, make sure you’re plugged in when gaming for optimal performance.

Roblox Client Issues

Sometimes the Roblox client itself becomes corrupted or outdated. Try these steps:

  • Restart the Roblox client completely
  • Clear your browser cache if playing through a web browser
  • Reinstall Roblox entirely if problems persist
  • Check if Roblox servers are experiencing issues on their status page

Hardware Limitations

While Roblox isn’t demanding, some games within the platform are more resource-intensive than others. Games with complex lighting, large maps, or many players will naturally run slower. Your RAM, CPU age, and available storage space all affect performance. If you’re running on 4GB RAM or less, consider upgrading or closing other applications.

Once you’ve optimized your settings and performance, you’ll be ready to enjoy smooth gameplay across all your favorite Roblox experiences.
