Was just doing some new performance profiling of my current project Gunfight Arena, and I noticed that our performance degrades linearly with the number of clients in the server. This is entirely expected, however I wasn’t expecting it to be this bad, and the reason for it seems to be the roblox PlayerList UI. This is especially frustrating because I’ve disabled this UI in the game so it’s not even visible.
In pre-render there are 2 0.005ms calls per player to render UIGradient effects. Then almost every heartbeat there is a 1.9ms call from Script_PlayerListManager.
My current game code (which I’m still seeking to make more efficient), runs in just 3.5ms. The rest of my frametime is taken up by Roblox operations, which would be understandable, except 25% of the total frame time is taken up by this PlayerList stuff when the PlayerList UI is entirely disabled AND no-one is viewing the playerlist in the escape menu.
We are sorry, but we will have to close this thread as it’s a duplicate to the other one mentioned here:
The other bug report has a ticket filed in our internal database and an engineer assigned to it, I’m not sure what’s the priority of this bug, but I will make sure to let the engineer know some developers are still experiencing it!
