In addition to a needing a good GPU (graphics processing unit) you need
a pretty good CPU if you are working with several markers.  The more
markers in a scene, the more it taxes the CPU.

In the ARToolkit libraries there are a lot of calls to operating
system's trigonometric functions and square root, which could be
replaced by lookup tables for increased speed.  In an earlier posting I
attached c source code for fast square root lookup, originally taken
from the www.NVidia.com web site.

You might also try recompiling a non-debug version with the optimizer
settings set to higher values.

well, it depends on where you loose performance.

the camera code that comes with artoolit isn't that great.
you might want to try thomas pintaric's version which includes optimized

windows video retrieval code.

if the processing power itself is the problem, then you might want to 
try a better compiler e.g. the one from intel, although i doubt, that 
this will help a lot in this case...

Hi
I''m using Artoolkit for tracking... I'd like to Know which is the best 
version of ARtoolkit to do that....I need high frames/second. I test 
Artoolkit 2.65 (windows) but results was not satisfactory.
What can I do for increase the performance?
Thanks
