fixed it by setting bSupportsManualVertexFetch of the VertexFactory to false. Still, I have way worse performance than with UE4.18. I mean, seriously, how is it possible that Epic changes low-level stuff without even telling **somewhere anything **about it? The low-level stuff is not documented at all anyway. This costs so much time and really annoys me.

From the 4.19 patch notes:

Vertexbuffer Objects now bind their SRVs directly instead of filling out a StreamDescriptor. Care must be taken when the Vertexfactory is initialized before the VertexBuffer as the bound SRV will become invalid if the underlying vertexbuffer is re-created. We do not support late binding of the data anymore.
