I see..., what could be a way to solve tha problems? my laptop isnt a good one but still is better than the minimum requerimentsI don't know where you would find that skin...but I can tell you that I seriously doubt changing the skin is going to fix performance problems. I'd recommend you be prepared for disappointment in that regard. Unless you actually like the colors you are changing, you are better off trying to fix the problem more directly.
Thank you, so, a way i think i can solve this is only using the program at onceAssuming you haven't done any upgrading to the hardware, and it is a Dell Inspiron n4010, your computer only barely passes the minimum requirements and does not meet the recommended requirements. There may be things you can do in Windows 10 that can help. See if there are any processes running in the background that are eating up system resources (anti viruses, Google Chrome, etc). Maybe turn on game mode? (unsure about that one)
As a last resort, you may want to look in to reformatting. If you can, look in to replacing the hard drive with an SSD, but I understand that may not be possible.
