Max 2010 rendering with only 50% CPU

[MasterBercon]

Many of our scenes render only using ~50% of the CPU capacity with 8 cores. I believe this is caused by the new bitmap handling. Using iBitmapPager.enabled = false doesn't make any difference.

Using only gray material without any textures render just fine with 100% but textures kill the performance right away.

Is there any workaround for this major problem?

Would be best to contact Autodesk for more information. They are aware of the issue and looking for a fix, but I do not know when this will be available. I'm not aware of any fix for this at present - the issue seems to affect all renderers in 3ds Max that use its native bitmap handling.

Do you happen to be using a core i7(nehalem)?

I saw somewhere that there is possibly an issue with Max 2010 and Hyper Threading.

EDIT: Sorry, I got it mixed up.

The thread is here: http://www.chaosgroup.com/forums/vbu...ad.php?t=45785

The conclusion was that it is just a Max 2010 bug...or could it be the Hyper Threading? It doesn't seem any attempt was made to see if disabling the HT helped.

Well, we do have i7 machines in the office; they run fine with hyperthreading and 3ds Max 2009.

Nothing new about this? I have exact the same problem with the difference that my machine (Dual Quad Core E5345) just use 30% processor capacity.

Quite boring to be forced to use the "old" 2009 version...

Not yet; nothing much that we can do about the issue on our side. I guess we'll have to wait for a 3ds Max 2010 patch.

I dont get it. prior versions of max worked find with bitmaps and threads and so on. So why try to fix something thats not broken? howcome all these problems all of a sudden?
