Help with D-force - no gpu

So I tried this a few years ago. I had no luck. Now I have å much better CPU so my renders are much faster, but I'm having trouble finding a low profile gpu so I was wondering if theres a magic way of simulating D-Force without a gpu.

    There's no "magic" way. dForce doesn't require a GPU in the first place. I did physics simulations before I got an Nvidia card.

    Studio tells me theres no device for simulation.

    dForce requires an OpenCL device - GPU or an Intel CPU with the Intel OpenCL driver. https://www.daz3d.com/forums/discussion/203081/dforce-start-here#latest

    Whata re your system details, especially the CPU, OS, and GPU?

    No GPU. CPU: I7 2600. OS: Windows 10

    OK, I did those simulations on a computer purchased in 2018 with an AMD processor, and apparently AMD CPUs no longer support OpenCL which--as Richard said--is a requirement:

    GPU = Graphics Processing Unit (in general a graphics card or CPU/mainboard with integrated GPU) so you must have one if you have a monitor attached to the PC.

    That is incorrect.

    A framebuffer for drawing the screen can be created in RAM and sent to the monitor. It's just slower than a GPU, which is optimized for graphics subroutines.

    The 2600 has Intel's HD 2000 graphics, which I don't think supports OpenCL (according to Intel's table).

    Do they really use that anymore?  Even my 14 year old Intel cards have integrated graphics with a GPU:

    "The GMA X3000 was an integrated graphics solution by Intel, launched in June 2006. Built on the 90 nm process, and based on the Broadwater graphics processor, in its Broadwater-G (Q965) variant, the device supports DirectX 9.0c. Since GMA X3000 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. It features 4 pixel shaders and 0 vertex shaders, 4 texture mapping units, and 4 ROPs. Due to the lack of unified shaders you will not be able to run recent games at all (which require unified shader/DX10+ support). The GPU is operating at a frequency of 667 MHz. "

    Many modern computers do include integrated GPUs, but it's not a technical requirement. Not if you're using serial connectors, anyway; I don't know about the HDMI era. Haven't been keeping up with the latest tech.

    Though to be honest, you probably do need a GPU to compensate for Windows 10's utterly garbage, bloated design. Anything to take the strain away from your poor processor.

    I run an AMD Ryzen CPU and a Radeon graphics card on my system. Even without CPU support I can still use OpenCL on the GPU.

    I did the same. My point was, if the OP has an AMD computer made after that, then they wouldn't be able to run dForce on the CPU.

    I made my computer after that. Frankly, I always assumed my dForce simulations were running on the CPU by default until this thread made me look into it and notice that it's on the GPU.

    Thanks for all the answers. To clear things up. I don't have a dedicated GPU. The HP Compaq have Intels onboard graphics. I've been trying to remove a AMD GPU from a Dell Optiplex 390, but theres some kind of mechanism wich secures the card that I'm not able to loosen. Oh well. I'll just have to do without D-Force I guess. laugh

    Did you try to unlock the retention clip?

    Have you tried the Intel CPU driver links from Rob's post above?

    also mentioned here: https://www.daz3d.com/forums/discussion/534341/error-initializing-opencl-kernels-when-using-dforce

    I am having the same issue:

    Processor: AMD Ryzen 9 5900X 12-Core Processor
    Dedicated GPU: AMD Radeon RX 6800
    Memory: 32768MB RAM

    Can no longer use d-force.
