Vray with Max 9 x64 - CPU usage problem

V-Ray V-Ray for 3ds Max Issues

Hi,

I have problem with rendering on this “combination”: Vray 1.5 SP1 + MAX9 x64 + Win XP x64. CPU usage (while calculating LC and rendering) is about 50-60% (sometimes 70%). I have try to set Dynamic Memory limit to 3-4GB - default geometry: dynamic - then CPU usage was 98-100% but the rendertime (and LC calculating time) was 2x longer than on MAX9 x32 with CPU 100% usage. Can someone help me with this problem ?

Hardware: 2xIntel Xeon Quad Core - 4gb RAM - WINXP x64

What would happen if you set the default memory to static, and the memory limit to e. g. 3000?

Best regards,

Hi Vlado,

If I set the default memory to static and the memory limit to 3GB - there is the same effect - CPU usage 50-60% :frowning: I’ve even try on “clean MAX” / MAX SP1 / MAX SP2.

any other ideas ? :slight_smile:

p.s. I’ve noticed that when I have LC+IRRMap “combination” with dynamic limit (3Gb) - LC is calculating with 50-60% CPU - IRRMap is calculating with 100% CPU - Rendering about 60-75% CPU (when displacement areas are rendering - CPU usage 100%) :expressionless:

Bios setting Maybe?

thanks for the advice - but it doesn’t make a difference :frowning: Still the same situation. We have Xeons E5420 on Intel Workstation Board Veronia S5000XVN Motherboard.

p.s. I checked on Dual Core - Vray on Max x64 works fine - 100% CPU usage.
