3ds max only using 15% of cpu

[scottghgh]

hi guys

 

i recenly upgraded to windows 10 and since (im assuming) i have been having trouble with 3ds max 2015-2016 only using 14%-15% of my cpu's, so when it reaches that mark it hangs and stops responding also the file takes about 10 mins to save.

 

i really have tried everything i can think of and im abit stuck now

 

if any one has any ideas ?

 

 

scene details : lots of rayfire objects baked out and 4 pflow systems. so its quite a heavy scene but seemed to be fine before

 

 

system spec is

32 gig dominator platinum

titan x

i7 3770k

win 10

 

thanks

as far as I know, Pflow operations have never been multi-threaded so i would check your performance using a different scene to make sure that isn't the bottleneck.

[scottghgh]

Thanks John

 

yeah it seems other files are fine. i dont realy have anything as heavy as this in terms of pflow scenes but....

 

i will have a look at bottlenecking and see whats what. im not a techy im a artist so i will have see excalty what that is and how to fix it .

 

thanks for pointing me in a new direction John

[scottghgh]

think ya right John its looking like the pflow bottlenecking

Most operations in 3ds max are still single core - so no matter how many CPUs you have it will only use 10% of the CPU. These are the things I know of that only use 1 CPU....

 

Pflow (mentioned already) - considering you have baked this out this is not your issue....

Saving a scene

Loading a scene

Running a .ms script

Most edit poly functions (connect, detatch etc)

Most animation and customize tools

 

Come to think of it you could probably make a smaller list of things in 3ds max which ARE multithreaded lol...

Rendering

Itoo Plugins

Rayfire (using GPU)

Most 3rd party plugins these days

 

Feel free to add to this list of things you know which are multithreaded

the file is just unworkable freezing everytime it reaches 15% cpu

 

so what are we syaing here, new processors are needed if i want more power or ?

 

@james no the pflow is not baked out, just the rayfire geo. everytime i do a cache or disk cache it hangs as well so..............STUCK:(

[scottghgh]

reloaded windows 8.1 and the hanging at 15% has gone

 

alot better performance as well FPS wise

 

and it saves in seconds

 

SAME FILE

I wonder what related to Windows 10 is contributing to the decreased performance?

Graphics driver compatibility perhaps? You may need to contact nvidia and wait until an updated Titan driver set is available before trying it again. Not sure what the likelihood of the graphics driver affecting the load/save time though :/

[scottghgh]

maybe have been a hard disk conflict with windows 10 maybe. as it was taking ages to save and wouldn't cache either

 

i do have 4 different drives so..could well have been that
