ORIGINPC Workstation Laptop ( windows 10 ) + RTX 3070 Gigabyte + Razer CORE X ( no CUDA )
Finally after waiting for two months I got RTX 3070 and try to Upgrade my laptop GPU by External one .
I pugged in thunderbolt 3 with my laptop , Razer Switcher has been installed and updated GPU Driver .
GPU showed in Device Manger and also connected with External Monitor but when I trying to use it in Render in Cinema 4D ( octane render ) error comes no CUDA selected when select 3070 from setting directly back to default when close settings window.
Talked with Razer Support they said need update firmware for GPU By Nvidia ( end of this year will be come ) , Maybe what he said is true, but I have seen many people working for him without problems .
I hope any body can help me
