quick question

[empty ingot]

Yeah

Checking off physics properties improves performance

[snow wolf]

nice, that's great for my game

[astral quartz]

so only parts that move will check for touches so this means unanchored part
but there still might be a very small improvement when a moving part gets close to anchored parts as the part no longer needs to check them parts
but I'm not 100% sure how Roblox does it so it might even be possible that Roblox still scans all parts close to a moving part even if it has touched set to false

if all your parts in your game are anchored then setting touch to false will have no effect on performance

[snow wolf]

weird, once I've set both CanTouch and CanQuery to false, the 'orange lines '[ctrl + f6] were much lower on average

not all my parts are in game are anchored, but most are

so it does seems like it helps reducing lags

The few moving parts will have to detect touches to anchored parts

https://devforum.roblox.com/t/new-part-collision-property-cantouch-activated/1132204

From this post it says you must turn off cantouch and cancollide in order to see a small performance benefit

Makes sense because even if cantouch is turned off it will still need to detect touches to handle collisions
