Mesh SubmitVBO Taking Up CPU Power
Hello, after looking at the "Profiler" to try to speed up my laggy game I found that one of the top items in the list was "Mesh.SubmitVBO". This item takes up 20%-40% of the total CPU usage. (Located under Camera.Render --> Drawing --> MeshRenderer.Render --> Mesh.SubmitVBO).
Is there a way to lower the CPU usage of this thing?!
Thanks in Advance, CarbonTech Software Admin
This is related to Mesh drawing (obviously, it's under the Drawing heirarchy in the profiler), so you must have too much of something drawing in your scene.
And "20-40%" isn't anything to worry about, I don't think... I've read people's support requests where this drawing function was taking up over 90% of each frame, and since it's a percentage, not a hard value, it's only relational to the other things that have processed in that particular frame. All the values (should) add up to 100%, and this just means that drawing takes up roughly 30% of the time in each frame.
Oh, and to answer your question:
Is there a way to lower the CPU usage of this thing?!
Yeah. Draw less. Less textures. Less verts. Less triangles. Less of everything. But like I said, it's nothing to worry about. I would really only worry about it if it was steadily above 80% or so.
Hmm, just checked the profiler again and found this:
Camera.Render : 81.4% - Drawing 42.5% - Culling 37.5% - Water.OnWillRenderObject() 24%
etc...
It seems that the pro water takes a lot of CPU to render (probably the terrain reflection). Is there a way to preserve the reflections from the terrain and lower the CPU tax?
Real time reflections are, and always have been, expensive. ;) Heck, even PC titles use cube maps (a type of pre-rendered reflection, similar to how a skybox is rendered).
