HP Sauce Posted October 30, 2008 Share Posted October 30, 2008 Currently our render station is taking far too long to do its job, so I'm hoping someone can estimate the speed improvements between the machines listed below or indeed suggest alternatives. Our 3D models generally weigh in at around 50-100mb, and are usually set up as a high-spec Custom Quality Renderworks with HDRI. Current spec:- VW2009, 32bit XP SP3 Single Core 2 Duo at 2.33ghz 4gb low speed ram 128mb Radeon x1550 Intended spec:- VW2009, OSX 10.5 Two Quad Core Xeons at 2.8ghz 4gb 800mhz ddr2 512mb GeForce 8800 (or Quadro FX type card if difference is worth the money) If anyone can estimate just how long will be cut off our render time from switching I'd appreciate it.

cad@sggsa Posted October 30, 2008 Share Posted October 30, 2008 I have the same frustration and glad I have not yet upgraded to 2009 as (I still need to shop around for a better Render program. I have had many suggestions from the ppl on here. nl. Artlantis, Strata3D, 4DCinema, ESP Vision etc. I still have to gain access to one of these programs demo as I,ve had endless problems from IT to see and compare. See some of the threads on here......

Jershaun Posted October 30, 2008 Share Posted October 30, 2008 In my experience, the only way to increase render times drastically (without losing quality) is to change render engines like C4D. Only way. Quote Link to comment
Vectorworks, Inc Employee Dave Donley Posted October 31, 2008 Vectorworks, Inc Employee Share Posted October 31, 2008 Hello highpass: Raytracing in Renderworks responds well to adding more cores. If you are talking about going from 2 cores to 8 cores I would expect raytracing of HDRIs to get between 3 and 4 times faster. With processors of the same clock speed adding more cores doesn't quite reach an exact 4x speedup because the threads need to managed, but in general raytracing in RW scales well with the number of cores. If the new processors have a clock speed bump then that may mitigate the thread management processing. I recently tested the number of cores versus render time for a raytraced HDRI scene and it shows a consistent progression in render speed (for 1, 2, 4, 8 cores). Quote Link to comment
HP Sauce Posted November 3, 2008 Author Share Posted November 3, 2008 Dave, thank you for the information. More cores seems the way forward. Quote Link to comment
