UI performance hit while moving.

Hey,

I've been trying to increase performance for the project i'm working on and i noticed that the UI seems to hitting performance quite a bit, but only while the character is moving. I found this a bit odd because the UI elements aren't moving or anything.

In the pic below you can see the UI section increases as I move and significantly increases when I open the inventory and move. When stationary there is no impact at all.



Does anyone know if I can reduce this performance hit somehow?

Thank you.

 

Click on your profiler where that spike happens and look at the code hierarchy to see what takes up the most time per frame. When you highlight a function in the hierarchy, the section of the graph that represents the workload that function puts on the CPU will be highlighted, so you should be able to find the function that creates the bulk of that UI spike by selecting one item at a time until you see a large chunk of the purple section lit.

If you can share what Unity internal functions are slowing you down, I might be able to help more. If it's not a unity internal function, I still might be able to help if you post the code for that function.

Good luck!
