I've got a Toshiba Satellite L75D-A. I think it's from around 2013. I have 8 gigs of RAM and an AMD-A4-5000 (1.50 GHz) video card.
So basically, it's not a gaming PC! :P
Oh... I see... I don't think your PC's that bad. I also tested it on a 2011 macbook air which is much less powerfull than yours and it was fine. Might be something else...
Well... It might be a bit too late for this jam but I'll try to include some disabling options next time. It might be hard due to time constrains though so I don't think I can place it on the top of the list of stuff to do. It would nonetheless be interesting to have an automated way to determine the performance of the player's PC and adjust stuff correspondingly.
