How do I boost my game performance?

Hi, I am making a game and it's going really slow on computers. My computer can run much better graphics than my game perfectly fine, but with my game, it lags a lot. If you want an example, go here: http://www.giantyeargames.com/forest-demo-scene.html

Please tell me some tips or just plain old how to speed it up.

Many thanks!

I haven't seen the demo but here's some general tips:

• Don't instantiate/destroy game objects a lot
• don't use really high polygon models
• don't use expensive (as in cost a lot of processing power) lighting and shadows
• don't use huge textures, especially read write enabled ones
• use texture compression
• if certain scenes lag, break em up into smaller scenes and transition between them
• If you have unity pro, use the profiler to find slow script areas
• if you don't have pro, consider asset store options, benchy is what I've been using, to find slowdowns
• reduce characters count, reduce particles count, reduce anything you can get away with
• find a good balance between performance and visual quality

Good luck!

 

Hi,

I forgot to mention in the post. I have pro. And all that is lagging right now is just the environment. There is some coding involved. And the only thing making it so slow is just the movement of trees and grass.

 

Use the profiler, it might give you some ideas as to whats wrong.

 

The biggest CPU user for the game is the Camera. How would I fix that to speed it up?

 

Take a screen shot of the profiler when a deep scan has run, with the worst lag spike showing. Show said screen shot to The forum. Somebody will know what's going on maybe.

 

This is what I got. (see attachment)

Mostly vSync is causing the issue.

 

Ahh that's just the delay for vsync. You seem to be getting between one to two hundred frames per second. Can you do things in the game that cause slowdowns while recording?

 

Thanks for that. I can see Unistorm is a fairly useless asset then. Spewing that much gc allocs per frame is entirely unacceptable for optimised middleware.

As mentioned above waitfor at high framerates generally can be ignored. For low framerates, it's usually a bottleneck like fill rate.

 

Whenever I record, Unistorm actually is the only thing that makes it just go a little slower. It's just when it rains though.

 

Lol well... I guess that's just the overhead of using that plugin. I imagine if you look through some settings within that whole thing, there must be a way to tweak the rain quality, or density... Something to make the rain less intensive. I couldn't help ya, might need to contact the Dev who made that plugin if you get poor performance specifically from it.

 

Unistorm isn't slowing down the game. It's the environment of the game. All of the tree movements, grass and water. Unistorm runs just fine.
