Is that comparible to texture atlases?

What do you mean?

Any chance that you push your current progress to the SFML experimental repository? I wouldn't mind if it doesn't build at all.

It's still too early to push something, sorry. But you can get all the relevant information about the new API in the dedicated thread.

...if you mean SFML2's current state

I mean SFML 2's next state :D
So the optimizations that I'm talking about are coming in the new API.

here's what a simple benchmark shows

These FPS are too high, the results are not really relevant. Add more stuff so that you reach ~100 FPS.

That's 13 pages which could probably compressed to one little list. ;)

Alright, this is clear now.

I had to instantiate 800 buttons to make the FPS drop to 100 FPS, however the "good performance" might happen due to using sf::View clipping to the window's area (haven't checked if SFML does culling in sf::View).

I know what a texture atlas is, but I don't understand your question. Well, now that I read it again, I understand that "comparible" meant "comparable" and not "compatible" :lol: so it makes sense now.

Distance fields are not comparable to texture atlases, it's just that a single "instance" of the glyph will enable to render it for any size, instead of having one instance for every character size.

Yeah, I'll try to post an update as soon as things get a little cleaner (and clearer) on my side.

It doesn't.

Thanks for clarification and sorry for the typo. ;)
