Cut Poly performance

[Michal_Z]

Hello,

I am experiencing fps drops during the runtime, I have two Recast Graphs, 5 moving navmesh cuts for each. The graphs are quite large, therfore they are precalculated and saved, loaded at the start.

Screenshot from profiler:

Screenshot of setting from one of the graps:

Is there any suggestiong what should I tweak to avoid these peaks?
I am also using this code to cut NavmeshCut when is enabled and remove it when it is disabled:

Force NavMeshCut disable to occur immediately

I ended up exposing the navMeshUpdates.lastUpdateTime, so I can only enable the AI after the nav mesh cuts have been applied. That seems to prevent the jumping. I’d like to hear @aron_granberg preferred answer to this issue though. That being said, strangely, the units don’t seem to be pathing around the cuts. In fact, it appears that sometimes the cuts don’t impact all of the graphs. Any ideas about that? Thanks!

Might it be connected somehow?

Hi

That’s a long time for a cut. How many cuts do you have in that tile? Or is it very detailed?

Using normal graph updates (using AstarPath.active.UpdateGraphs(bounding box)) can sometimes be better. They are often more expensive in pure CPU time, but they are much better parallelized and will likely not cause as much work to be done on the main thread.
