If I had them, I wouldn’t even have to use FFlags in the first place, this would solve 99% of the problems I have with Roblox.
If advanced graphics settings are out of reach, at least add a way to separate render distance from graphics quality, but for the love of god don’t make graphics settings automatic.
the flags to disable directX and enable vulkan renderers (vital for improved performance, not just for lower-end systems to run smoothly but for those who simply want a more stable and less jerky experience.)
flags to enable or disable UI changes (very useful for developers to force enable a-b testing ui to ensure their UIs work well with them)
any flags that adjust rendering (excluding or range limiting those that affect atmosphere and lighting to prevent cheating) to override the hugely flawed auto quality algorithms that often make Roblox look worse than the users device is capable of.
I don’t have much experience with terrain, is this not something game developers can alter using scripts? If so, speak to developers of the games in question and ask them to add a setting to adjust it or disable it.
