world generator this what i made in unreal 4.12, its little bit laggy.

is it made with blueprints ? if so try the bp->c++ convertor (Nativization of bps assets)

yes and why

it will help performance someone said that the gain was 10x

That’s been a very arbitrary number thrown about, but in reality even if that were the case I wouldn’t expect to see quite that same increase from the nativize function, as the auto-generated code will not be as optimized as it could be if written by an experienced programmer.

That’s not to say there’s no improvement. Honestly this looks like either a performance issue with the engine on the user’s machine, or that the recording from OBS was causing significant lag.

sorry mate it wasn’t me who tested it but here is the “benchmark” :

can you tell me how
