BloxBoost lifts Roblox's 60 FPS cap on Windows 10 and 11 without new hardware or account. One preset, one button, back to the game.
Stock Roblox locks to 60 frames per second. On a tired CPU or old integrated GPU, this cap is cruel — the client still burns cycles, but you only see every second frame worth of work. The game stutters, camera lag wins, and weak hardware gets blamed for what is actually a bottleneck by design.
BloxBoost removes that cap and tunes Roblox's performance flags the same way the community does by hand. It wipes the cache so the client doesn't drag old assets through RAM, and bumps the game's CPU priority so every core pushes the frame rate higher. Older laptops actually feel the difference.
Every change is reversible with a single Reset button. The app writes only Roblox's own settings file — the same one Bloxstrap and FastFlag packs edit — so there is no injection, no process memory patching, and no file corruption.
Ultra removes the frame cap entirely and uses the simplest lighting model (Voxel) to maximize frames on machines that barely run Roblox at 30 FPS. Visuals are stripped, but the game is playable.
High caps at 360 FPS and also uses Voxel lighting — best for budget desktops and older laptops where you want a big frame-rate jump without total visual gutting.
Balanced sets the cap to 144 FPS and keeps ShadowMap lighting, so you get smooth gameplay without losing the game's look. Safe middle ground for most players.
Quality is for machines that handle Roblox well. It caps at 240 FPS and enables Future lighting for real-time shadows and modern visuals.
Switch presets any time. Reset first, then pick a new one. That way old settings don't clash with the new preset.
Free forever, no account login. You run the app, hit one button, and Roblox launches. No signup carousel, no tier picker, no background process watching you after you close the window.
Fully offline. The app does not call home, does not send telemetry, does not check for updates automatically. Everything happens on your PC.
For Windows 10/11. Installs in about a minute using the standard Windows setup from the downloaded zip.
Built for weak hardware. The presets are tuned for integrated GPUs, budget CPUs, and laptops with thermal throttling. High-end gaming rigs will see the same FPS unlock, but the real win is watching old machines come alive.
BloxBoost writes only the client-side settings file that Roblox reads on launch — the same file community packs edit by hand. It does not inject code, does not patch game files, does not read process memory. That said, Roblox Corporation sets the rules. Check the game's terms if you are unsure, and use this tool at your own discretion.
Yes. Windows 10 and Windows 11, 64-bit only. No Mac, Linux, Chromebook, or online version.
BloxBoost skips unknown or renamed flags instead of forcing them. Future updates won't corrupt the client. Your old preset might do less, but the app will still run and the Reset button always works.
Yes. Press Reset and every flag is removed. Roblox returns to its original state in one click. You can then apply a different preset or leave it vanilla.
