[freenode] <nemo> Jupstar: does ddnet really have that many changes to text? I'm thinking in particular in context of games

14:24

[freenode] <nemo> Jupstar: we use pre-rendered textures for the time counter just for Ã¦sthetics, all other text is generated on the fly from the ttf, the most frequent text changes being either chat or % changes in some game attribute

14:24

[freenode] <nemo> and the latter is only a few characters once a second. big deal

14:25

[freenode] <nemo> in terms of web browsers, I'm not sure what they do. I bet it depends on circumstances.

14:25

[freenode] <nemo> there's all sorts of crazy things one has to support on a web page these days

14:25

[freenode] <nemo> I remember discussing w/ the mozilla guys why adding absolutely any animation to a web page spiked CPU - text was the main culprit

14:26

[freenode] <nemo> these days browser have gotten better about putting that into textures and offloading to GPU - in part because GPUs have gotten better too

14:26

[freenode] <nemo> but regardless, I don't see why the choice of font should have any significant impact at all

14:26

[freenode] <nemo> why not let players use whatever font they want?

14:26

[freenode] <nemo> well. they probably can right?

14:26

[freenode] <nemo> just copy over the asset

yes, but in many locations we might be assuming the width of the font

15:00

instead of using a calculation to get the actual width

[freenode] <nemo> huh

15:16

[freenode] <nemo> odd. definitely should be calculating width of the rendered texture from the font

15:16

[freenode] <nemo> well. apart from maybe approximations

15:16

[freenode] <nemo> esp due to unicode

but lots of UI stuff is fixed size

15:17

boxes having fixed size, would look weird if they were different size in each language

[freenode] <nemo> ehhhh

15:17

[freenode] <nemo> you could just have a safety margin if it's a key part of the game layout

15:18

[freenode] <nemo> but yeah. overflowing happens

15:18

[freenode] <nemo> you can choose between truncation, animation scroll, or resizing

15:18

[freenode] <nemo> deen: https://issues.hedgewars.org/show_bug.cgi?id=275 this is still open - it bugs wuzzy more than the others I think

15:18

[freenode] <nemo> https://issues.hedgewars.org/show_bug.cgi?id=275#c3 in particular is our problem

the problem is that in the background is a highly refreshed game, so you cant just invalidate rects and render "a bit"

17:22

so you have to "render" the text textures to the framebuffer every frame anyway

17:22

and that is not necessaraily faster then compute the few vertices

17:23

but that depends on the GPU cache, i cant tell for what GPUs , but i assume modern GPUs just keep pretty much all textures near to the processors

17:23

ofc only bcs teeworlds doesnt use alot of textures

17:24

tripple A games are different level maybe it profits from rendering ready textures instead of swapping the font texture(with the game textures) always (edited)

[freenode] <nemo> Jupstar: what I mean is, you don't need to rerender the texture itself every frame

18:01

[freenode] <nemo> so... why does changing the font help

18:01

[freenode] <nemo> that's the part I don't get

18:01

[freenode] <nemo> how does any font change at all, result in any significant perf increase

18:02

[freenode] <nemo> since the font should only be regenerating textures in like 0.0001% of the frames

i dunno what you mean by changing the font

18:13

the theoretic problem i see is, that the text that was rendered on textures to not rerender it every frame also needs processing alpha blending etc

devs, can you make it so when my friend changes their username for teeworlds, it will change their name in my friends list as well?

no, that's not possible
