I Have a 4090 and My Render Times Are Underwhelming

justcreated1111

Hey guys, I have no Idea what is going on, but I recently upgraded from the 3070 to the 4090 which theortically should be almost triple the performance. I had done some tests with the 3070 prior to swapping to this beast, and the render times are only slightly faster 5-10%. 

All my compenents are up to standards besides my physical ram, which I am waiting for. Right now It's sitting at 16gs but will be upgrading to 64, but I don't see how ram would make a difference if I could fit the same scene in with my old setup. Completely lost. Any help would be apprciated.

A possible reason could be the recognition of the daughterboard by your operating system.
When hardware changes too much you have to make sure that Windows takes it into account. When changing a motherboard, for example, it is strongly advised to completely reinstall Windows. Of course, it could work without doing so, but it would't be (at all) the right way to ensure that the OS uses the available hardware to its full potential.

** Did you reinstall Nvidia drivers after installing pluggin'in the graphic card ? If not, my advice would be to 1/ uninstall Nvidia drivers completely and all traces of it (Revo, Voidtools Everything, etc.). 2/ reinstall NVidia Drivers. That's the minimum you should do for such a jump in hardware.

I went from a 2070 to a 3090 and the difference is phenomenal (but I also changed CPU, motherboard, RAM, etc. so I reinstalled Windows). You should definitely feel way more than 5 or 10% with a 4090. WAY more.

** Another reason could be the bus speed of your motherboard. But you wrote that the rest of your computer is "up to standards" (whatever that means)...so I guess that's not the problem.

There is a benchmark that you can run and compare your times to a base image.  Based on other benchmarks, the 4090 should be able to render the benchmark image in just over 1 minute.

But...a 3090 will do it in about the same amount of time as well.  It seems, after some investigation from other users, that the current version of iray drivers in Daz don't really take advantage of the 40-series cards...yet.  Testing of the private betas of Daz (which should be released to public betas soon, and eventually as public release) I guess does show some imporvement, but not as much as Daz 4.16

I switched to Studio drivers and did a fresh install of Daz, and my render times have drastically sped up. I still think there is potential for faster rendering when Daz fully intergrates the new cards into their system.

I was able to complete the benchmark in 1:22 seconds, 1900 iterations, which as far as I can tell, is about 40 seconds faster than a 3090.

That was not necessary ;)

But glad to read it works better now.

That's almost a full minute faster than the 3090 times they were giving the past two years which is right in line with nVidia's marketing hype. It may speed up a bit more, but not a huge amount, with nVidia fine turns their iRay SDK & DAZ uses it in DAZ Studio.
