Getting started

Questions about low-end Roblox and BloxLite.

Will BloxLite slow down my PC after I close it?

No. The boost applies only at launch, and closing Roblox returns your system to normal. No background service runs after you're done.

Do I need administrator rights?

No. BloxLite runs as a standard user. You can keep it on a USB drive and use it anywhere.

What if my PC has 2GB RAM or less?

BloxLite will help, but Roblox itself needs at least 2–3GB free to run smoothly. Check your Task Manager before launching.

Can I use this on Windows 7 or older?

No, BloxLite is built for Windows 10 and 11 (64-bit). Older versions lack the APIs required to trim memory safely.

Does this unlock higher FPS caps?

No. BloxLite optimizes your system so Roblox can reach the FPS it's capable of on your hardware. If your GPU is weak, you'll still see limits.

Is this safe? Could it break my system?

Yes, it's safe. It only frees cache and adjusts process priority—nothing permanent or critical. Restart your PC anytime to fully reverse it.

Can I use this with other optimization software?

Yes, but be cautious. If you're already using system-wide memory cleaners, run them separately and not at the same time to avoid conflicts.
