That's true... but I think it's not only texture size that causes performance issues, the number of textures that need to be looked up also plays a role. I'm no engine coder however, so I might be wrong. I bet Your Computer would know more about that!

I'd stick to the multiple textures idea, thanks for your efforts to help though

I became unsure as you wrote that.. Wanted to look it up.

If all of that is correct "today" I do not know. Well, things to be considered:
- polycount doesn't matter as much. 1-300 polygons (during that time, cross all engines) = the same use of performance
- drawcalls; the amount of textures is the most important "bottle-neck"
- Don't bevel edges into very small borders
- Use geometry rather than alphas

So, is 3x1024 a better optimisation than one 2048? Well I guess the "safest" bet would be to create a 2048 and include a fourth 1024 texture into it = utilizing all of the texture space (same memory usage) + lower drawcall.

In your case I think you should do whichever fits you best. Ultimately I don't think you're going to stumble upon performance issues developing your mod.


I personally will have to start thinking about these things..
