Fluid Brush Not Working though GPU Supports DirectX12

I have Nvidia GEFORCE GTX 1660 but still not coming
it to does support DirectX 12

Hi! I have the same issue that you do with my animate fluid brush tool. I have a NVIDIA NVS 5200M video card, and I discovered that even though my card supports DirectX 12, I don't think that it has feature level 12_0 support.
If you have a Windows 10 computer: 

To check, I followed these steps:

1. Click Start and click or type Run.
2. In the Open box, type "dxdiag" (without the quotation marks), and then click OK.
3. The DirectX Diagnostic Tool opens.
4. On the System tab, information about your graphics card is shown, including the DirectX version. You can see the name of your card, as well as how much video memory it has.
5. Click the Display tab, and look at the Feature Levels. I think that if 12_0 is supported, it would be shown in the Feature Levels. My video card doesn't display it, so I think that is why the fluid brush does not work for me (see screenshot).
   
   If your 12_0 feature level is also missing, I would make sure that your video card driver is the most up-to-date.
   With administrator rights (logged-in as an administrator), Click Start and type Run -> devmgmt.msc -> Device Manager -> Display adapters -> double-click your display adapter.
   Click Driver -> Update Driver and follow the steps.
   
   Unfortunately, I am unable to update my video card driver anymore (it is already at the most up-to-date version), so I would have to buy a new video card. 😞
   
   I hope that this helps!

Try opening animate with your gpu
right click animate > run with graphics processor > high performance nvidia processor

Hello,

I've been checking on this page every few weeks to see if there's been any update. Unfortunately there hasn't been any from the adobe team whatsoever. 

I am also experiencing this issue where the Fluid Brush Tool is disabled regardless of the fact that my GPU does support DirectX 12.

I have a GeForce GTX 660 video card, and it does support DirectX 12 .

If someone could help out with this it would be much appreciated.

- Thank you
