Roblox FPS unlocker: Roblox now uncaps FPS itself, and how to go further
Here’s the honest 2026 answer a Roblox FPS unlocker search is really after: you don’t need the old standalone tool anymore. Since May 2024, Roblox uncaps your frame rate from its own settings. Open Settings, set the frame-rate limit above 60 or to your monitor’s refresh, and you’re done. Where BetterBLOX still helps is everything after the uncap: FastFlags in BetterStrap let you pick a frame-rate target and trade rendering quality for frames on any PC.

Roblox uncaps FPS now: what’s left to do
Here’s the honest update most guides haven’t made: in May 2024 Roblox shipped a native FPS unlocker right in the client settings. You no longer need a sketchy standalone tool just to break the 60 FPS ceiling; flip the setting and your frame rate climbs to match your monitor.
So why does BetterBLOX still show up when you search “Roblox FPS unlocker”? Because a raw uncap is only step one. Anti-aliasing, post-processing and 3D grass all cost frames your GPU could be spending on the number instead, and the built-in toggle touches none of them. That’s where FastFlags come in: the tuning the setting doesn’t give you.
FastFlags go past a simple uncap
FastFlags are client-side settings Roblox reads at launch. BetterStrap writes them to a local file before it starts the client and puts the performance ones behind named modes and saved profiles, so you don’t have to hand-edit JSON to get a result.
- A frame-rate target you pick — 60, 120, 144, 165, 240, 360 or unlimited
- Anti-aliasing, post-processing and 3D grass, each on its own control
- A rendering backend you choose — Vulkan, Direct3D 11, Metal or OpenGL
- Save a profile per game and map it to the places you play

Tuning for a low-end PC
An uncap can’t manufacture frames a weak machine doesn’t have, but FastFlags can free some up. On a budget laptop or an older desktop, turning post-processing off, stripping 3D grass, dropping anti-aliasing to 1× and lowering texture quality reduces how much work each frame costs, so games run smoother and feel more responsive even without a high-refresh monitor.
Cut the render load
Turn post-processing and 3D grass off and drop anti-aliasing so the GPU renders cheaper frames.
Set a target you can hold
Pick 60, 120, 144, 165, 240, 360 or unlimited, so the frame rate matches what your monitor can actually show.
Keep it reversible
Every control has a default. Go back to it any time, nothing is permanently changed.
Client-side by design
FastFlags are Roblox’s own client settings, written to a local file before launch — nothing is injected into the game and no memory is touched. BetterStrap’s presets and graphics controls only set flags that change your own client: frame rate, anti-aliasing, post-processing, 3D grass — never flags that touch gameplay or other players. It can also check your list against Roblox’s live flag list and mark names the client no longer knows, and the raw editor writes whatever you type, so anything you add by hand is your call.

Roblox FPS unlocker FAQ
Frame rate, FastFlags and performance, answered for 2026.
Do you still need a Roblox FPS unlocker in 2026?
Not the old standalone kind. Roblox added a native FPS unlocker to the client in May 2024, so the classic third-party “unlocker” tool is largely obsolete. What is still worth doing is going beyond a plain uncap: BetterStrap sets a specific frame-rate target and trades rendering quality for frames — anti-aliasing, post-processing and 3D grass — from one FastFlags page.
How do I unlock FPS in Roblox?
Open Roblox settings and raise or remove the frame-rate cap. That is the built-in unlocker. To push further, launch Roblox through BetterStrap and apply a FastFlags profile that sets your frame-rate target and drops rendering quality on top of the uncap. On macOS that needs multi-instance switched on first.
Are FastFlags allowed, or can they get you banned?
FastFlags are Roblox’s own client settings. BetterStrap writes them to a local file before launch: nothing is injected into the game and no memory is touched. Its presets and graphics controls only set flags that change your own client — frame rate, quality, rendering — never flags that touch gameplay or other players, and it marks names Roblox’s live flag list no longer knows. The raw JSON editor writes whatever you type, so anything you add by hand is your call. See our answer on whether FastFlags are allowed for the full picture.
What frame rate can Roblox actually run at?
With the cap removed, Roblox will render as many frames as your hardware and the game allow, commonly 120, 144 or 240 to match your monitor, and higher on strong PCs. The ceiling is your GPU, CPU and the experience itself, not an artificial 60 FPS limit.
Will unlocking FPS help on a low-end PC?
Removing the cap alone won’t create performance a weak PC doesn’t have, but FastFlags can. BetterStrap’s Performance mode drops anti-aliasing to 1×, turns post-processing off and strips 3D grass, and a lower texture-quality preset takes out the rest, so a budget laptop can feel smoother even if it never reaches a high-refresh number.
