Open NVIDIA Control Panel > go to "Program Settings" (and select Roblox Studio) > change "Monitor Technology" to "Fixed Refresh" > Reopen Roblox Studio.

If that alone doesn't work, go into the "Studio Settings" of Roblox Studio with Alt + S > "Rendering" > Change "Graphics Mode" to Vulkan.

Then to verify what your FPS is within the Roblox Studio game testing, when in-game within Roblox Studio, press Ctrl + Shift + F4, "Render" and/or "Heartbeat" should be at your desired framerate (mine is 180).

this worm emote is supposed to have my arms/legs in a perfect worm-like line, but as you can see, its back and forth left and right if i can describe it that way.

(this is not the only emote affected, its just the easiest to show)
