I have problems of lags in a big patch,
I have approximatively 100 objects jit.gl.text2d witch are all moved independently by line objects.
Problem: In a sequence i have some freeze moments (during about 100 or 200 ms i think).
I tried to optimize scheduler settings. It’s better now but the the problem subsists.
Here is one element of my patch.
Even with this very simple patch, IT’S NOT PERFECTLY SMOOTH !!! Why?

Thanks for your help

I’d advise looking into using bline (triggered by bangs from the same qmetro that’s driving your display) instead of line.

Though I’ve found your patch works fairly well with the time grain to line reduced to 10 and running at 60 fps.

I’d suggest optimizing your patch to work with one line object at it’s lowest possible time grain, moving between start and end points with jit.xfade, and adjusting the position of each object before banging (aka. automatic 0).

I’ve got this one running at 40+ fps with 400 objects…

just for curiosity i try this last patch in my machine and the framerate drops down and down when i go with more than 30 objetcs! with 40 objects i get 5 FPS!!

im in win7 64bit with the last Max version on a
Intel® Core™ i7-940XM Processor Extreme Edition
(8M Cache, 2.13 GHz)
and a gpu ATI Mobility 5870 1GB GDDR5

not a slower machine, but…

any idea?

thanks!

anyway setting at 400 objects im getting 20FPS… half of you..
im curious which machine do you use?

btw, i always get better performance using gl.text3d instead of gl.text2d… with 400 objects and gl.text3d goes to 40FPS..

best!
