also tested benchwell on the 5.2 demo. the GPU was lame with low score like it's an oldie. 18% top at the task manager. CPU delivered as others on the CPU chart and at 100%, and more wierd, while testing on CPU the GPU got to 25% load....

Target SL 15
GPU rendering 2x 3090 RTX
CPU Threadripper 3970x ( Denoise)
Priority: Normal
Denoise: YES (CPU)
Multyligh: YES
ISO: 100
Time: 15 Minute

Considering you don't have visually any control over Maxwell Render internal Denoiser, i generally avoid it.
Topaz is far better and visually immediate.

so is it possible that the 5.2 demo simply doesn't utilize my card properly? I was expecting at least double the speed, judging from NL publications. and it's almost the same with worst image quality (in GPU) in higher SL ....

1) Consider the rendering time i posted regardless the Threadripper 3990X is based upon an Overclocked CPU with all cores at 4GHZ.
2) with a stock 3990x a 30 minute rendering could become an Hour or more.

3) For the fireflies in GPU rendering, considering your scene, i noticed is caused by a lightsource named maxwelLayeredMaterial26136
setting that to ZERO, will remove completelly the fireflies in the render.
This strange bug happen only while rendering with the GPU.
If you render the scene with CPU engine, you can easily leave this light source on.

4) If you check the console when the GPU rendering start, you will notice a loot of errors about shaders not completelly supported in GPU engine.
The grass used in your scene is correctly loaded in CPU engine, while GPU engine can't handle it.

Speed wise, Maxwell Render is far behind Octane and Vray, especially with GPU rendering.

Quality Wise, if you start your rendering during the night and stop them when you wake up, you will have a wonderful, clean nice looking render.

Speed wise, Maxwell Render is far behind Octane and Vray, especially with GPU rendering. --> but why can't I get 100% GPU power like CPU ?? devs need to answer that.

1) The light causing problem probably is related to the LIGHT Hotspot on the Ceiling.

2) I hope this not the problem about your gpu, but i know NVIDIA placed software side, an Ether-mining hash rate limiter, reducing the GPU performance while mining.
This limiter has been placed only on RTX 3060 and maybe RTX 3060 TI
Maybe Maxwell Render share code wise something to those kind of limiter introduced by Nvidia?

Test your GPU with the tools i link to you, and compare thescore of your GPU.
If your score is similar to other users, could be a problem related to Maxwell Render, or maybe to the Demo Version.

https://gpu.userbenchmark.com/ : good for comparing scores

https://benchmark.unigine.com/heaven : good for testing stability on short period and benchmarking your GPU.

https://geeks3d.com/furmark/ : this higly stress your GPU, better set up a 100% fan usage to keep the temps under control.

If with all 3 benchmark your GPU usage is at 100%, and score similar/ on par with other 3060, the problem could be related to Maxwell Render.

well, running two of the tests- pointed me to a simple conclusion: maxwell is not using the GPU as it should. the score at userbenchmark was very high and the geeks3d test showed also a-100% use of the GPU. maxwell is just not using it for more than 7-8% while other software (topaz, tests...) does. guess I'll have to wait and see if NL gets it done right :(

Contact Nextlimit / Maxwell Render Team and request a trial license to use Maxwell Render unlocked for a week.

I’m sure they will release one for a loyal long therm customer.

Maxwell Render / Studio 5 is way better then the older release.

For sure there is still more to improve.
Some minor bugs and some unfinished things could make your experience a bit rough.
Hope the NL Team will not fall back like within the V4 release.

Last thing you can do:

1) download DDU driver ( Display driver Unistaller)

https://www.guru3d.com/files-details/di ... nload.html

2) start your system in Safe Mode
3) start DDU and remove all the Nvidia files

4) start back Windows in Normal mode.
5) instal back the latest studio Driver from Nvidia.
6) restart your system.
7) uninstall completely Maxwell Render
8 ) use something like CCleaner to clean the Windows registry.
9) restart your system
10) instal back Maxwell Suite.

If even after this your gpu doesn’t ramp up at 100% Probably is something coded inside Maxwell working not correctly with RTX 3060 more then a driver issue.

If you can find another different GPU to test would be great.

maybe I'll try that , I'm a bit skeptical it can help.
NL support still has to help me with my v.4 license but they're on holyday or something, I'm waiting for a week now to support ..(!) for my ticket.
