bad jit.gl.pix peformance

December 22, 2013 | 12:10 pm

Every time I use jit.gl.pix objects in my patches I get big performance decreases (from 60/55 to 20/25 frames).
It happens with all the jit.gl.pix examples and also with very simple gen patches (like using simple arithmetic).
The max windows tells nothing. Any ideas whats the problem here? Thanks!!

Macbook pro late 2012
NVIDIA GeForce GT 650M 1024 MB
OSX 10.9.1
Max 6.1.6

I use mac osx 10.6 and only have faster frame rates ! Could be because your using the newest OS.

No problems here on a similar machine running 10.8.5 and Max 6.1.3

Gen performance has been consistently awesome for me…

Could it be a Mavericks thing?

if it is a retina machine, the recommendation for optimal graphics performance on retina devices at the cost of resolution, is to disable retina support on the Max application. Get Info on the application in the finder and check the box for "Open in Low Resolution".

Thanks for the input, but no retina machine here.
Maybe its a maverick thing. I’ve also noticed that sometime the same patch runs fine and sometimes not (without changing anything). I have a tricky performance this weekend with many beamers and I’m a bit scarred..

Is the slowdown related to the number of jit.gl.pix objects you have in your patch? A while back I found a nasty bug that degraded rendering fps in discrete steps for every 10 or so jit.gl.pix and gen objects in a patch. It was fixed but maybe something like that reappeared? http://cycling74.com/forums/topic/bug-gen-killing-render-fps-please-test/

There is definitely something weird with jit.gl.pix in my OS because sometimes it runs fine and sometimes not, but I haven’t found anything. I need to try a bit more. Thanks for the link DTR!
