these are my specs and it's on a 400 by 700 image but with a huge amount of layers, like 150 at this point. yeah I now it's a lot and my computer isn't that good but the thing is, this lag is new. pre-patch I could go up to 200+ before things would slow at all. something has changed or broken in this version for me. even smaller projects are showing signs as they grow.
