    Revit and Dynamo lagging and VERY slow

    I got a new computer recently and since then everything turned bad with Revit. The computer is rocking awesome but Revit and Dynamo (also Autocad and Civil 3D) are so damn slow and lagging.

    Specs laptop:

    Alienware 17 R5
    CPU: Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz, 2208 MHz, 6 core('s), 12 logic processor(s)
    GPU: NVIDIA Geforce GTX 1070

    SSD: Samsung SM961 NVMe PCIe M.2 512GB
    HDD: HGST Travelstar 7K1000 2.5" 1TB

    Microsoft Windows 10 Pro

    Revit 2019.2
    Dynamo 2.0.2
    Autocad & Civil 2018

    This are the prestations when Revit is running: (see image)

    Does it has something to do with the used GPU? I notice that the 8gb is using al of the data instead of the 16GB. But i'm not an IT-specialist so i don't know. That's why i'm asking. If so, how can i change this?

    Already tried:
    - Un-/install all the software
    - Load different projects
    - Reboot laptop
    - Close all unnecessary software

    Since it is a laptop I would check to see if it is thermal throttling. I've used MSI Afterburner in the past to check fan curves and temperatures.

    Make sure you turn off the Intel on-board graphics chip in the bios so Revit is using your GTX.

    That processor looks not optimal for Revit at all, since so much of it's processing is done single-core.

    What advice did you get/What research did you do before you decided on this configuration for a Revit machine?
