Render speed win7x32 vs win7x64
show user profile  Endycool
Hi everybody. I'm currently render an extense sequence in diferents computers at my home, and i'm shocked of how slow is one of those computer compared to another one that it's almost identical.
My sister's pc is a q6600 with 2gb ram, running win 7 x 64.
My father's pc is a q6700, 2 gb ram, win 7 x32.
On my sister's pc each frame takes 20min, while on my father's pc each frame takes 5 min!!!. Both cpu are almost identical, the only big diference I can see is the OS. I was wondering if anyone has experience something similar... i could install win 7 x32 on my sister's pc, but i would have to do a complete format, and i don't know if it worth it.

that's interesting and not entirely unexpected.

check you don't have lots of crap running in the background on the 64 bit configuration.

Nop, there's not a lot of crap running in th back. In fact I have installed win 7 on that computer just a few weeks ago, and it has only a few programs installed...

well, there's not much we can do. if that's your benchmark results & your scene fits in 32 bit max, looks like you have identified your optimal solution.

ensure you've installed all hotfixes, service packs, etc.

max & windows.

amd64 has addtional instructions that usually gives a performance boost over 32 bit windoze but if they're not being used, 32 bit will win due to reduced memory requirements.

personally, the only difference i identified between 64bit and 32bit max is that 32bit one crashed every 5 minutes... maybe thats just me though.

Nope. Not just you. The 32 bit is a crash-fest.

on small scenes (fully patched) ?

obvoiusly if you hit the memory limit bad things will happen.

Yup. Even on small scenes, max 32bit was buggy as heck for me.

32 bit max is what works faster on win 7 x32. I've tried to install Max32 bit on the win 7 64 computer and it's the same shit.... i think it's the Os, but i'm not sure... it's a relatively small scene but with a lot of refractions and it's a 2000 frames animation, so 20min each frame...

I think you should use 32bit max :)

1. you have no idea how fast a girl can destroy the internal efficiency of a 64bit workstation

2. 2gb ram is the problem for the 64bit version which is made to handle 48gb and more
it's like testing the speed of a Wally powerboat in your inflatable backyard swimming pool, results will be awkward.. :)

the 64 bit version will only be running slower than normal if its run out of memoy & swapping.

you'll be able to tell this due to constant hard drive activity.

that said - 2GB is very low for apps such as max so you'll hit that limit soon if you haven't already.

more memory doesn't equal faster but not enough = slower.
