Mac Pro Dual 3ghz Quad-Core, 32 gigs of Ram, 5770, SSD, 44fps. Dissappointed.

Pretty disappointed.  Just setup my new machine, and it only registered about 44 fps.   Why?  Other mac pros here have a lower clock speed, less ram, and they're getting 60-70fps with Keyshot 2.  Is Keyshot 3 that much slower?

Assuming you are using the camera bip file. I find this hard to believe since I am getting 39fps on an i7 quad-core with hyperthreading, running at 2.3Ghz.

Is KeyShot pegging all 16 threads?

Hey cash68

When I/we upgraded from KeyShot 2 to KeyShot 3 on my home machine and on four of our office machines, we consistently saw a 25% reduction in FPS.  However, I don't know how well the FPS between KeyShot 2 and KeyShot 3 correlate because my KeyShot 3 workflow felt lighter/quicker than KeyShot 2.

how many cores/threads does your mac pro have?

[cash68]

It's a dual quad-core machine.  Keyshot is pegging all eight CPU's.   I installed Keyshot 2, and instead it got about 59FPS, so I guess that's more appropriate.   Didn't realize Keyshot3 was so much slower.

[guest84672]

It all depends on the scene. Try other scenes and you will see that KeyShot will perform that much faster.

Also, no hyperthreading?

[cash68]

What do you mean?   How do you know if you have hyperthreading enabled or available?   

[guest84672]

It is a new machine, right? The new quad-core processors all support hyperthreading, so you should have 16 threads available.

[jiyang1018]

quad core with hyperthreading would run as 8 cores.

[cash68]

Thomas, no, it is not new.  It is a heavily upgraded Mac Pro 1,1.   Its processor is an Intel Xeon X5365, 2 of them.   So dual-quad cores.  I see 8 CPUs getting maxed out when running keyshot.  Are you saying I should see 16?

I think your score of 44fps in KS3 is very much in line with what can be expected from a dual Xeon X5365 (@ base clock 3.0GHz).
Remember, you're talking about a CPU that was released in 2007.
A brand new dual Xeon E5-2660 (@ 2.2GHz,albeit with 8 cores per CPU) workstation will blow your system out of the water and be about 3 (!) times faster than your rig in KeyShot.

Please have a look in this list:
http://www.cpubenchmark.net/cpu_list.php
This ranking of CPUs gives a pretty accurate indication of KeyShot performance.

To prove my point:
My Intel 3930K gets a score of 11987 in that list. I get around 70fps in KS3 (@ base clock 3.2GHz).
Your dual Xeon X5365 gets a score of 7640. That's 64% of a 3930K.
64% of 70fps is...45fps. 

I, personally, will ALWAYS consult that list when in the process of choosing/buying a new workstation.
Just my 2 cents of advice...

I think there's nothing wrong with your hardware or system configuration.

Ah.  Gotcha.    I was expecting more like 70+ fps... but I'm still happy.  It cranks compared to my old system, which struggled to get over 30.

[guest84672]

ok - no hyperthreading on this chip set.
