I am testing H19 on a Mac m1 max and especially the viewport is very slow. Since my main WS is using a 3090 I very seldom encounter any slowdowns there even with heavy scenes so first I thought it just was that the M1Max was slow. But: Loading a simple 1 M tris 3 M vert model as fbx renders like butter in Blenders viewport using wireframe, triangles or even with Eevee rendering while over in H19 I get 15 fps with just the basic smooth shading. It is like everything is done in software or something. Both viewports use OpenGL so it is not that. Is there some known tweaks one could do? Switching of some feature? Knows bugs? Should it be reported?
