Great, almost two-times faster :o)
But 7 FPS is still very low, i will try to understand library a make
some performance tuning.
I started with quickly set profiler and got these results:
Func Func+Child Hit
Time % Time % Count Function
---------------------------------------------------------
1252,490 12,2 1305,109 12,7 15819 nuiGetVal(class
nuiXMLNode *,class nglString,float) (nuiflags.obj)
1205,943 11,8 1249,593 12,2 3360
nuiGLDrawContext::DrawShade(class nuiRect const &,class nuiRect const &)
(nuigldrawcontext.obj)
1143,250 11,1 1143,250 11,1 26956
nglFontBase::GetGlyphInfo(class nglGlyphInfo &,unsigned int,enum
nglFontBase::GlyphType) (libngl.dll)
More than 30% of time was "wasted" these functions. I think especially
nuiGetVal can't get so much. I'm going to find some sort of "caching"
for this function.

Hi!
Thanks to me being under heavy jet lag, I found some time to fix a lot
of performance issues in NUI tonight. All of the problems had to do
with text rendering. There are still some problems left and I think
i'll find some time to do it soon! (nuiEditText needs to be rewritten
using nglFontLayout, nuiFontBase should be a bit smarter when it comes
to texture management and rendering, etc...).
I'm adding these changes to the CVS right now.
Let me know if things are getting any better for you. (text rendering
is what is really killing nui right now, we really need to implement a
better solution to render a collection of glyph FAST, it's easy but
still has to be done ;).

I'm running Windows XP Proffesional, Detonators 52.70. I understand
that NUI is not fully optimised, but score is very low. I'm going now
to experiment a little bit more with NGL - maybe something is wrong
with my configuration.

Hi Martin!
I haven't had much time to work on NUI lately and there sure have
been some speed degrading changes in the last few month. I plan to
track them down and fix. Of course we could also use some help as
profiling rendering and other CPU hogs is not trivial.
What OS are you using?

Hi guys,
first of all let me thank you for NGL/NUI library. I was excited by
it's (NUI) screenshots. So i download 0.7.10 version a try to
compile it. About six hours of experiments ended up in reading mail
archive, configuring CVS, downloading fresh sources, exploring new
README and finally installing stlport, againg compiling and viola -
i got it :o) Than i tried nuiTest and i see some problems with
speed. Am I getting something wrong or 5 FPS are normal on WXP,
MSVC6, ATHXP 2000+ and GF4 Ti4200?

Martin Sliwka
