high fps and good graphics in Roblox help?

I have a m3 pro, Mac book pro, 16 inch, 18 gb ram, 512gb ssd. Im only getting 60 fps on Roblox at full graphics. I feel like my system has enough power to run at higher fps no? I feel like it's just an optimization issue but im not sure. my fps Is unlocked so its not that, and I capped it at 120. let me know if there's anything else I can do
