Your laptop is stuck at 60 FPS and the game feels choppy. BloxBoost unlocks Roblox's frame cap, cleans up junk files, and gives the game higher CPU priority—all in one click, no new hardware needed.
Roblox caps itself at 60 frames per second by default. On an older laptop or budget desktop, the client still works hard to reach that cap, but your weak GPU or CPU can't keep up smoothly. You see stuttering, frame drops, and input lag even though the game *should* run faster.
Worse, Roblox piles up cached assets, temporary files, and logs over time. More junk on disk means slower load times and less breathing room for your RAM.
BloxBoost fixes both: it lifts the frame cap (so you can actually reach 144, 240, or even unlimited FPS if your hardware allows), wipes the cache, and tells Windows to prioritize Roblox over background tasks.
BloxBoost edits Roblox's own settings file using the same method that community optimization packs use. It does not inject code, patch game files, or read your memory. It simply tells Roblox to render at a higher frame rate and use better lighting for your hardware tier.
It clears Roblox logs, temporary files, and cached game assets—sometimes freeing up hundreds of megabytes. It also bumps Roblox to High CPU priority so Windows doesn't steal processing power for background updates or notifications.
Every change is reversible. One click on Reset and Roblox is back to factory defaults. The app is fully offline, free, no background processes.
**Ultra**: Your laptop fans are loud, games barely run, battery dies fast. Ultra strips away fancy lighting and bumps the frame cap to unlimited. You get the cleanest visuals and the most FPS.
**High**: Your PC is a few years old or is a budget machine. High caps FPS at 360 with simple lighting. This is the most popular choice—it cuts lag in half and still looks reasonable.
**Balanced**: Your machine is decent but not new. Balanced caps FPS at 144 and uses better lighting. You get smooth gameplay without sacrificing the game's appearance.
**Quality**: Your PC is relatively strong. Quality allows up to 240 FPS with full real-time lighting. This is overkill for most weak machines.
BloxBoost does not modify any game binaries or inject anything into the Roblox process. It only writes to `ClientAppSettings.json`, a settings file that Roblox reads when it starts. That's the same file that community optimization packs edit by hand.
Before using any performance tool, check Roblox's Terms of Service to understand what is and isn't allowed. BloxBoost itself is open-source MIT licensed and fully transparent—you can read every line of code.
BloxBoost is free forever, no trials, no locked features. Just download the zip, run the installer, and use.
Yes. Windows 10 and 11, 64-bit only.
Yes. Click Reset and every flag is removed. Roblox goes back to vanilla in seconds.
Press Reset, then try a different preset. If the game still looks off, close and reopen Roblox normally.
