Today I benchmarked #GodotEngine 3 on lossless image formats.
I loaded the default icon a million times:
PNG (3305 bytes) took 1.758 seconds
Optimized PNG (1939b) took 1.853s
WebP (1378b) took 1.778s
WebP indeed has a small speed penalty compared to unoptimized PNGs, but it largely makes up for it in size.
EDIT: Forget I said anything! The bottleneck is elsewhere, I renamed icon-opti.png to i.png and it's the fastest now >_>
#Benchmark #WebP #Aseprite (used for conversion)
The speed is actually the same for all format when the file name is the same length.
In short, the bottleneck is probably gdscript.
Godot 4 benchmark coming right up!
After doing a benchmark on Godot 4.1 with a serious image (2-3 MB depending on the format), I conclude that the loading speed is exactly the same.
Thanks for reading, and use whatever image format you prefer in the end.
As for me, I'll mainly use webp for… web stuff (sounds extremely what-it-says-on-the-tin in retrospect)
