Hi mack,
I fear you have answered your question already. Your hardware seems not to be supported well enough. And when it happens in Blender then it happens of course in Bforartists too. Since we rely at Blender.
You have now two opportunities. Upgrade your hardware. Or downgrade your software. Means an older version of Bforartists or Blender.
Sorry that i don’t have better news.
Kind regards
Reiner
