Game is slow

Hello to everyone!

I have downloaded all the logo, face and kit packs and integrated them with FM15. The problem is that sometimes the game becomes too slow, but I'm not sure what is causing it. The worst lag comes when I am at scouting lets say 100-150 players in a list. When I choose one to see the stats, it takes a second to open the page and I thought it may be caused from the extra graphic packs. The game and all the extra features are installed on a samsung ssd, so I doubt it's the drive that causes the problem. The processor is an i7 mobile and the laptop has 6gb ram memory. Also i'ts kind of hard to believe that 50 kbyte png's slow down the game, so do you believe that there is something else slowing down the game? Or do you have any suggestions to make?

Thank you in advance
