Roblox's Built-In 3D raycast vs Self-Implemented 2D raycast

[twardy95 (Twardy)]

I have a quick question related to raycasting.

Would a self-implemented 2D raycast module be faster than Roblox’s built-in worldroot:Raycast() ?

I don’t need its 3D functionality, so I’m wondering if I should get a 2D raycast module instead, and would such module be faster than the one Roblox provides?

Honestly, it depends on the module itself, and how optimized it is. Yet, thinking about it critically and an educated guess would say yes it is faster.
