Hello, I just got into blender about three days ago, and it’s really addictive 
(Sorry if this is a little bit off topic in this forum… I couldn’t find a place where my topic could fit better)
My problem is that after using blender for a while (15 minutes or so), the program gradually slows down until it practically comes to a screeching halt. Starting a new project does nothing to help, but if I close blender then re-open it, it magically becomes fast again. My computer isn’t too old (bought last year) and i’ve been going easy on it, so it’s still in very good shape… Is there a way to solve this problem? is it a RAM issue? I fear that i’m doomed to either restarting blender every ten minutes, or buying better hardware 
Anybody have any advice?
