If they just brought this back and fixed it, nobody would be complaining here.

Wow isn’t it amazing that local fast flag support is being removed…? Atleast give us the option for no framerate limit, because what is this bs.
I believe videos like from Sharkblox and also several news accounts recently tweeted this. I am not really up to date with this thread but that’s what i heard

Where did this come from? Are they really removing the ability to use fastflags??
Most people won’t be affected by this except cheaters
Hello, I have a question about the framerate cap feature. Is it possible change the cap using keybinds instead of opening escape menu and switching between 60/120/144/240 values…?

There is a fast flag for that. You can re-enable UI hiding.
(Taken directly from the bloxstrap wiki, however this won’t be of much use considering all of them are being removed.)
GUI hiding
Relevant flag(s): DFIntCanHideGuiGroupId
This is a group-based FastFlag, therefore you must be in a Roblox group for it to work. It can be made to work with any group you’re currently in - see the flag editor for that, but if you don’t feel like doing that, and want to avoid confusion, you can just join the Bloxstrap group. Here are the following keyboard shortcuts it provides for toggling the visibility of GUI elements.
| Key combination | Action |
|---|---|
| Ctrl + Shift + B | Toggles GUIs in 3D space (BillboardGuis, SurfaceGuis, etc) |
| Ctrl + Shift + C | Toggles game-defined ScreenGuis |
| Ctrl + Shift + G | Toggles Roblox CoreGuis |
| Ctrl + Shift + N | Toggles player names, and other BillboardGuis that show up above a player |
Pro tip: Ctrl + Shift + G + C + N makes for a nice screenshot 
Enabling this will show a freecam option in the menu. That option isn’t supposed to actually work, so just ignore it.

I’ve been using Alt+Enter for true fullscreen on Roblox since 2019, and back then, you didn’t need to install a ClientAppSettings.json — the "FFlagHandleAltEnterFullscreenManually" was already set to false by default. Everything worked perfectly without any manual setup.
Later on, the situation changed. There was a period when Roblox completely removed the "FFlagHandleAltEnterFullscreenManually" flag from the client itself. I remember the exact version when this happened — it was “version-da93e2c4e15845b1”.
At that point, even if you manually installed a ClientAppSettings.json and set "FFlagHandleAltEnterFullscreenManually" to false, it still wouldn’t bring back true fullscreen, because the flag literally didn’t exist anymore in the client release.
We had to reach out to the Roblox client engineering team about it, and around October 2022, a Roblox engineer confirmed that they would re-add the flag back into the client.

So basically, that’s the history behind it. Hope this clears it up a bit!

Too bad they didn’t set it to false after they have added it back. It would be great for them to fix the bugs related to it and set it to false by default the moment they plan to remove or limit client ability to adjust FFlags.

Yeah, the reason they didn’t set the flag to false by default when they added it back is because we actually told the Roblox client engineer to just reintroduce the FFlag into the client first — since, like you mentioned, there were still bugs with Alt+Enter and true fullscreen. So we agreed it’d be best if they just added the flag back in, and we’d handle setting it to false locally through ClientAppSettings.json. That way, it was completely up to the user and didn’t cause issues for everyone by default.

Sadly, what you said is just IMPOSSIBLE, due to how roblox sees it’s future. Hoping for something to change, but for now I mess only with render distance flag, to get 40 FPS with max render distance

I have to meddle with internal flags to get good performance on my high-end pc, roblox is insanely unoptimized. maybe if roblox offered deeper graphics settings on their own like most games do, we wouldn’t have this problem. you should be able to get higher render distances without having to ramp up the shader qualities and AO. It’s comparable to piracy, if people were given more options, people wouldn’t need to mess with external programs.

i’m mostly advocating for flags to be left alone because i want the choice to have flags on. roblox’s rollout system is infamously horrible because if you’re in a slow rollout channel like i am you’re stuck stranded 99% of the time waiting decades for new features instead of just being able to turn them on in a beta menu like studio.
there is zero good reason for removing flags because it hurts every single user who needs more than the normal client offers as everybody has come to expect the ability to turn on new features or change existing ones which would make no sense to turn into settings

i hope they don’t remove all flags or just remove the flags that cause people to glitch around the map, I use fastflags to disable the full screen titlebar as it gets in the way of my screen or exclusive fullscreen so i can get a smoother video, removing fflags hurts every user who needs more than the normal client which is pretty much everyone, i’d rather pentest some of the flags and patch them first over disabling all of them completely

Hey everyone, we appreciate the feedback we are getting from passionate users who use flag overrides for good faith purposes like performance. As we said before, we want to avoid interfering with good faith flag flips, whilst also not requiring we hunt down every flag that can be used for evil. That’s why we promised we would implement an allowlist of flags that we know are safe.
I looked through the list of allowed flags and, though we can’t share the exact list yet, I can say with relief that it is quite broad, and includes tens of the most commonly used flags, including several of the performance overrides offered by community tools such as Bloxstrap. Rest assured that this use case is not being dismissed.

RIP the grass length/speed ones if they don’t make the cut, terrain grass is really laggy and developers shouldn’t be able to force it on us.
