Painting Tool is WICKED Slow

Hello,
I am creating a map and when I use the paint terrain tool to paint the terrain texture, it is really laggy all the sudden.

Specs:
GTX 1080TI Aorus Xtreme 11GB
16GB Ram Installed
Ryzen 7 1800x @ 3.6ghz
Double 2Tb Drives

 

I think thats normal, its been that way for me for ages now, in general the world editor as a whole is beyond useless other than for placing objects.

 

If you're using the autopaint tool, that is just the nature of the beast.
If you're using manual paint, it may be due to map resolution or brush scale.

 

I've had this when a decal road was nearby with the option 'over objects' was selected. Deselect it, and reselect it later is an easy solution to that.

 

The terrain is actually 8192 by 8192, which is quite large, but I was hoping to use most of the map, and have extra space left over to add on in the future.

Yes, I have always had that issue with autopaint, but I am never using it again for that reason.

 

Same issue here on an 8k terrain. Freezes my entire game and makes random terrain while the game is locked up.

 

I had problems with forming the terrain on one of my maps, it was very laggy. And then i tried to delete the forest object and it fixed it. For now it is like butter, when sculpting the terrain
