I must ask why do you need CreateObject? Only thing I ever needed CreateObject is for places where I know vehicles will be spawned on. For interiors I use streamer as well but let the player be freezed for 1-2 seconds until they have loaded in the objects properly.

Anyways to answer you, you can't do anything about it. It's a static limit (https://sampwiki.blast.hk/wiki/Limits) and it's not changable (unless you want to decrease it, then just redefine it to smaller, but 1000 is the max and you can't go above it).
