So I have this game I’m trying to optimize, but right now, with just this on the screen, it’s freaking out.
I have a bunch of hexagonal cells made up of 6 walls, with 3 line renderers on each (the inside, the white outline, and the black outline). Inside the cell, I have a bunch of squiggles on the ground, and some random plants scattered about. The squiggles and plants are both just sprites.
Everything ran perfectly at 60 fps when I had a grid 1/4 this size (15x11) – but switching to a larger grid at (30x21) I’m below 30 fps. I have a 3070 in my computer, and if mine can’t run it, there will be problems elsewhere.
As I start looking through the profiler, it’s clear that I don’t really understand what’s happening, or what I might do to improve the situation.
Can anyone give me a good idea of where to start? I know a little bit about the physics optimizations, but the rendering stuff is a mystery to me.
I’m not a rendering person but if you’re going to show some profiler output for timing, by far the most important thing to actually show are the times which you’ve unfortunately cut-off in the image above.
Those batch numbers look scary though. Looks like nothing is being batched.
Maybe a tile-map might’ve been a better option here, not sure.
– Ah you’re right! It seems like the times are like 26.xx ms, 19.xx ms, 19.xx ms 19.xx ms, 14.xx ms.
If I can get them down below the double digits it might work! xD
… It’s interesting. Static batching was the first thing I tried. I set all the objects which don’t move in the scene (all of them right now), and made sure isStatic was turned on. I also went to make sure that static batching was turned on in the edit - project settings.
Fear your 30x21x3 Linerenderers are the issues (or is it actually 3 per wall, not per hexagon?!). That’s just a lot and I bet it’s not actually the GPU bottlenecking but the CPU. Try setting resolution to 720p - does that improve the FPS significantly?
If not (vs 1080p), the CPU is the limit.
Unfortunately this is tricky since I assume you want to keep this randomization of your cells.
An idea comes to mind to eliminate the linerenderers:
Generate every tile shape onto a render texture at game load and then turn that render texture into a sprite.
To save memory and improve batching, you could limit the number of different cell shapes to 100 or so. Nobody will notice that it’s not all 100% randomization.
