Roblox PC Tweaks: Higher FPS and Smoother Play, Safely
Roblox is light by design, but big, crowded maps can weigh down any PC. What matters most: manual quality control and raising the frame-rate cap in Roblox's own settings, with no outside tools that put your account at risk.

Warning: FPS unlockers and modified launchers
Roblox is protected by an anti-cheat system called Hyperion. Old “FPS unlocker” tools and modified launchers that change the game's internal settings can conflict with it, and Roblox has restricted much of what they used to change. The official setting is enough, and it's the safe option for your account.
Questions gamers ask
Yes, with the Maximum Frame Rate option in Roblox's own settings, no outside app needed.
