what would resoult in better performence? not using textures at all or using textures (multibale textures)?
-
textureless is faster but…
-
textureless in your case: default texture is assigned
if you are facing performance issues
using textures ,you can optimise by -
using a texture atlas as textured objects look
better for example this and this uses a single material mostly
-
using vertex colours.
-
and if you have the models export it as a single mesh from your 3d program uv mapped to your texture atlas
-
but still in the end depends on the style of your game if you really want no textures
Not using textures will provide a slight performance boost but a more noticeable video memory usage savings. Your game will have to be highly stylized to avoid using textures because in most games a ton of the detail comes through textures.
If you aren’t already pushing your max gfx memory or if CPU is your bottleneck then you probably wouldn’t even notice a difference.
