I am rendering scene and I see the cpu at 100% durring FG pass but when it gets to AA it slows to 40% to 90% is this normal? or is there something wrong with my computer?

It could be a bug. Could you provide the scene (as simple as possible) so we can check it?

Thanks Jure give me a few days and I will send. It is only doing this on a i7 on 4cpu computers it does not do this.

Any one out there had any trouble with Kray using all the CPU speed? I have a i7 920 and I am seeing speeds of 10 to 90% in the task manager. Any special settings that need to be done in bios? Rendering in Lightwave render is 100% very confused here.

dbl post. update I just loaded old scene and it is rendering 100 cpu now. Could the model slow render speed? I know it can make it render slow but in my case it is all over the place ever second.

It could be some surface issue rather than model itself... Try finding the offending surface and then report back so we can check it.

I sent you PM. Thanks for the reply

Hello,
I have the same probleme on i7 with Kray 2.1. with 2.0 cpus go to 100% but with 2.1 it works bad 20% to 80% (with the same scene) same pblm with BNR 4, and Kray 2.1 make a lot of error with the script and i need to reinstall all plug and script.

I7 860 / 8gb RAM / QUADROfx 1800
2 *I7 860 / 8gb RAM / gt 210 (little render farm)
Quad core q9600 8gb Ram /quadrofx 1700

all computers in XP 64bits LW 9.6

what's new in the 2.2 (link in news letter don't works)

thanks

on a other frame of my scene, all cpu are at 100% for prerending raytrace and AA.
how can i found the "bad textures" witch slow my scene?

First try disabling nodes. Those are most often cause of problems. But if you find the problematic surface please send it to us because we need to check this problem.

ok i try but i havent node textures i tried

Use Kray surface override and select "disable all". If this helps then it means it's surface problem. Otherwise it's something else.
