Hardware / Re: New Computer Setup CPU 5950x vs 12900K

« on: 2022-01-20, 10:07:31 »

Undervolted 5950 @4.4 - 4.8GHz.
12900k can match 5950's performance only when enormously overclocked which is useless in every aspect.

Hardware / Re: Hardware optimization?

« on: 2021-12-23, 13:36:51 »

Just set fixed all core frequency and find lowest stable voltage for that frequency. Then you will get maximum from your CPU with your cooling solution.
Do not use voltage offset mode and single core turbo boost frequencies...it is not worth those extra 10-15% speed in single threaded tasks.
With fixed freqv. and fixed clocks it is much easier and more accurate to find stabile lowest voltage.

Test 10min. rendering and you will see how temperatures will rise. Try to keep it under 80°C. If you reach 90+°C, reduce the frequency by 100 mhz and again, find lowest voltage....or buy two tower cooler :)

[Max] I need help! / Re: Cube map seams

« on: 2021-05-15, 10:52:43 »

Try to avoid using denoising and sharpening/bluring in frame buffer... then no visible seams appears.
You can check seams in PS if you cut and paste one square of cubemap and place it to correspondent another square.
If visible seams persist then it is probably issue on Layama side during resampling process...

[Max] I need help! / Re: Lot of noise when reflection/refraction override is enabled

« on: 2021-05-07, 21:51:01 »

So now it is more clear. The main diference is, that I mostly do cloudy day renders without sun or additional interior light. That's why I came across this noise problem when refl./refr. override is enabled. This scenario is not so common and I am assuming that optimization in rendering process in corona 6/7 was targeted for more common scenario(sun + sky)...therefore I see masive noise increase in direct light  render element.
Can be this considered as a bug or a simply unwanted regression in visual noise level in corona 6/7?

For now I will stay with corona 5, I am occasional "designer" (just few renders per year) so this is not something critical for me. Should I drop some report in bug section, or is this topic enough for devs to take a more indepth look?
Thank you again. ;-)

Hi, thank you for reply.

Hmm where did you find the wrong scale? I checked dimensions on every object and they are same(utility - measure  = object properties - general tab.) My system unit setup is 1 Unit = 1milimeter.

I also created just box with fliped polygons with one hole as window and the same issue - after enabling reflection/refraction override  the noise has increased in corona6+. Left and right render both 30s.

I also deleted the ENU folder to be sure that some script is not causing this issue...

[Max] I need help! / Lot of noise when reflection/refraction override is enabled

Hi, when reflection/refraction override(black/gray/white color or tonemapped jpeg) in scene settings is enabled, masive noise is apearing using corona 6/7 latest daily. Corona 5 without issue.
Noise is visible in Direct render element, Indirect is very clean. Increasing LSM has almost no affect.
I am using only corona sky(Hosek Wilkie) in scene environment as a light source.
Tested 32s render, adaptivity off, UHD cache, GIvsAA 4, LSM 4, MSI 4, High.clamp 0, adapt. light off, random sampler new improved. Corona5 with portals, for corona6/7 no portals and env.sampler changed to adaptive.
Renders in corona 7 identical with 6.
Scene in attachment.

Any workaround? Similar issue mentioned @cecofuli in this topic https://forum.corona-renderer.com/index.php?topic=27953.msg170860#msg170860

How about this system I've just spotted is a better one than the dual x5650 it's about £30 more expensive?

HP Z600 Workstation 4 x Xeon X5672  3.20Ghz 12 GB RAM

Compare benchmark results here https://corona-renderer.com/benchmark/results   and you can search for additional CPU information (number of cores, max turbo multicore frequency) here http://www.cpu-world.com/CPUs/Xeon/Intel-Xeon%20X5672%20-%20AT80614005922AA.html

If you have exactly i5 4460, then 2x xeon 5650 will be roughly 4.5x faster, and your frame times will drops from 20min to 4.5min. and you will be waiting 225 hours for 3000 frames. If you will be rendering on both machines, it will be less :) .
As you mention, your scene is simple, so 24GB RAM in triple channel will not make rendering significantly faster.

EDIT: roughly math, 184hours (i5 + xeons)

The xeon E5640 is 9 years old architecture @2.8GHz.  2x E5640 is still slower than one 8core Ryzen 2700x (300€). You will be still waiting days, days and days to render 3000 frames.
Interior animation with just 2 windows is not easy task when you dont want to spent a lot of money on renderfarms.

If 100% photorealism is not so important you can use unreal engine or unity to render animation. It will take one or two days to prepare scene(PBR textures, prepare objects for prebake shadows/ realtime GI, set reflection cubes, ...) but you can save a lot of monney and also time. 3000 frames can be rendered in game engines ~ 30min on your computer. GPU is not so important, even office dedicated low end graphics card is enough.

Forest pack is not RAM hungry until you creating millions of instances. Check how many primitives unique.: and how many Instances: do you have in corona render scene stats.
