Question by erikkubica · Sep 06, 2016 at 01:40 PM · performanceperformance optimization

Performance issue new project vs everything deleted in old project

Hi there,

I have seen a lot of answers but they don´t describe my situation.

I have noticed that my "game" with terrain, 4 walls an sphere(player) and some client <-> server communications takes 10% cpu usage on non development build. Same result if i just run it in unity on the fly.

My cpu is skylake i7 2.6ghz 4 core 8 thread + gtx950m

But also if I remove all objects from game (incl. camera) the fully empty game uses 8-10% cpu

But if I create an new empty project the game uses 0% cpu.

Is there anything in background which can cause game without gameobjects and scripts to use so much cpu? Or is scripts loaded even if they are not attahed to objects or they are attached but objects are not spawned?

Other info: Unity5 downloaded friday, W10 Anniversary. + I have also tried to run builded empty game with nvidia, but nothing changed.

Thank you


Edit: Turning on vsync helped to reduce from 10% to 5% (200fps vs 60fps). But 5% also feels much.
