Reducing cpu-usage?

Questions & Answers

Hello!

I can’t find the issue why my game is slow as hell…
The FPS drops under 5!!!

Draw Calls: max. about 250 Saved by batching: up to 1300
Tris: under 350k Verts: under 200k
Used Textures: max 5 2,7MB
VRAM usage: 3,7MB to 25,8MB
VBO Total: 2706 - 19,4MB
Shadow Casters: 0
Visible Skinned Meshes: 0

It’s a multiplayer game.
State control is only used for the low-poly player. Everything else in the scene is static. (see batching…)
At the beginning i use Network.Instantiate a few 100 times, so the traffic after 15 seconds is:

bytes sent: about 70k
bytes received: about 10k
message bytes queued: about 50k

After playing 2 Minutes without any further use of Network.Instantiate:

bytes sent: about 120k
bytes received: about 60k
message bytes queued: about 80k

There are max 2 Players and they only use the build-in Character Controller, Mouse Look, Character Motor and FPSInput Controller scripts.
I don’t use the Update-function in any of my self written scripts.

CPU usage without testing the game: about 10%
(old slow pc(AMD A4-3300), but thats ok, it should run on android and iphone)

Running a single (builded) instance of the game (all Objects instantiated):
CPU usage: 90% to 100%

Running two instances(Server and Client):
CPU usage: always 100%

Running two instances on 2 PCs(Server and Client):
CPU usage: 90% to 100%

If someone could gave me a hint how to reduce CPU-usage, i would be very happy :slight_smile:

Thank you in advance

Hard to say are you using real time shadows with trees or something that’s high poly. or what the case may be go and see when dose it get better or worse.

I have unity free and you should tell me what you have a lot of in the scene.

Wish you the best.

Run this through the profiler. Find out what methods are using most of your CPU power. Optimise those areas.

Without identifying a specific bottle neck in the profiler you will not be able to progress.
