Question by Ben Holmes · Feb 10, 2012 at 11:22 PM · performanceoptimizationoverhead

Overhead performance spikes

I'm in the later stages of optimizing my game and I'm seeing spikes labeled as Overhead up to about 28ms which is clearly unacceptable.

What kind of recourse do I have for optimizing Overhead stuff? Is there anything I can do about this?

See Performance Optimization and Graphics Optimizations

Thanks but those two articles discuss optimizing scripts and GPU stuff (which I have done) and don't mention Overhead at all.

Are you using C# or Javascript? There are some language specific things to be aware of.

If your overhead spikes to at regular intervals, it's likely that you have lots of temporary objects being created per-frame and every once in a while the Garbage Collector is causing a slowdown trying to clean it all up. Here's an article on MSDN explaining the GC and performance issues.

I'm using C#. Also garbage collection is something I'm aware of but it should not be reported in Overhead. There is a separate report for GC.collect.
