Bsp taking very long time to update now

I know its 2 yrs old, but my question is as orig. author.
Usually my BSP’s do update, though a few seconds given my rig isn’t 100% SOTA and I expect that ,- although atm they aren’t doing that, and building them takes way too long, though I do have some semi-complex designs :wink:

Using 4.19.2, is this possibly a bug or am I asking too much of my computer given how much its drawing ?
5101x5101 terrain 256x2 and 10 components ( 50 or so BSP, various design/size )

If my current system isn’t enough @i5 3750 8gb ram GTX 950 2gb , is more about the ram tho atm I have 16 or more about more powerful cpu + GPU ? I know about the requirements which I match just fine overall, though from what I’ve read here, 32gb is optimal .
