AMD Graphics card support?

Here is some of the output while trying to run the version of BubbleLab VR on the steam store. Let me know if you need any more info.

If there is a way to get it work with an AMD brand graphics card, let me know.

@peteristhegreat last I checked, there was no way to support AMD cards due to a dependency to Nvidia Flex.

However, you may be able to use it now! Check https://docs.nvidia.com/gameworks/content/gameworkslibrary/physx/flex/index.html

I would have to update the version of flex that is being used under the hood and perhaps it would work then

This is a great find! Thanks for the reply.

I can try an exe with flex and report any logs for an AMD graphics card. I am running an AMD Radeon RX 5700 . I checked to see if my card can get its support software updated to run AMD: Radeon Software Version 16.9.1 or above.

I have Unity installed on my machine... I can try something like this: https://developer.nvidia.com/blog/video-tutorial-flex-unity-plugin/ and report back, but if you have a beta built with a newer version of flex that may be a bit faster to try out.

This looks like a list of D3D11 cards... and mine is not listed, but some of its family is... maybe the list is incomplete:

Update:
Looking at DirectX Diagnostic Tool (dxdiag.exe) it says I am up to DirectX 12, so that shouldn't be a problem.

@peteristhegreat thanks for checking on your compatibility. Let me see what I can do regarding the flex version upgrade.

And thank you for reporting this! I'm glad there seems to be a path forward -- was not the case when I made this game initially
