Some months ago I realized that i couldn't visualize any streamers in dop simulations. I just wanted to let others know that I solved the problem by installing an older version of my graphic card driver - geforce gtx 570 (driver version 411+ back to driver version 337.88)

Probably solves the problem I had in H12 too, where polygon faces would not show in viewport (primitives worked).

so yeah, cheers

Houdini 13.0.570 should also fix this problem with the 344 driver series.
