in Technical Help (nuts n bolts)

Hi every one. So here's my big surprise. 2 weeks ago i had an issue with my computer who wouldn't start anymoresad. I went to the after sale store where an update issue was detected. As i've Always find my PC slow with DAZ, i asked the technicians how to speed up daz a little  without spending a lot of money. He proposed me a ryzen 5 4600g, telling me that it would speed up 2X my DAZ renderyes.I have a small configuration(8g Ram, Windows 10, Athlon 3000G, Daz3d 4.22). So there was 2 characters Max(genesis 3 and 8) in my scenes. I went back home, Happy with my new CPU. Started a render.Oh my god, it is so slowwwww, it seems that it is 2 times slower than beforeangry. I have tested a few render made before and it is clearly much slower than before. 2 days ago i upgraded to windows 11 and Daz 4.24, still slower than with the previous configuration. any ideas ?

    8GB RAM is very limiting, I would suspect that that is the main bottleneck. It's possible that the overhead of handlign more threads on the nw CPU is tiping you over a boundary. I would have thought that RAM was at least as effectie an upgrade as the CPU.

    The only change in your system was the CPU? Comparing the datasheet the new CPU is much better than the old one. (Comparsion at CPU-Monkey: https://www.cpu-monkey.com/en/compare_cpu-amd_athlon_3000g-vs-amd_ryzen_5_4600g)

    But your whole system is very limited für DAZ - the "G" CPU have integrated graphics. Maybe you should look in the BIOS of your System if it has to much RAM for the graphics: if that was less before, the system will "swap" - what results in a much slower speed. 

    Has your system a HDD or a SSD - I would recommend a upgrade to a SSD. Unhappily at the moment price for that increase.

    Hi, thanks for your answers. The main program is installed in my system hdd wich is an SSD. My Media library is on an external drive(4 TO Seagate Expansion SCSI Disk Device).

    Hi,

     

    Im new here, so don't know everything, but my renders were horrifically slow(10+hrs for a single character, no scene).  I then unchecked the CPU rendering in render settings, kept CPU fallback, and let the GPU on my laptop(that has a 4060 GPU), and the render times dropped to 1hr for high sub d character with modest scene.  Plus, my CPU doesnt cook.

    Does your pc have its own GPU, or is it running off integrated graphics only?

    Hi, Thanks for trying to help. I don't have a graphic card. only integrated graphic on my main board and the 4600g.

    For rendering you absolutely need a dedicated GPU (as many CUDA cores as you can afford and at least 8GB) and preferably at least 2x your current RAM. Your MB will be a bottleneck in any case as it's a DDR4 board.
