No, not that we have noted. We are developing on a MacBook Pro and a desktop Gamer PC around 4 years old. However, I also have a "on the road" mediocre non-gamer Windows Laptop, which is now 3 years old. This one is good to run tests on and so far it is performing good. Our challenge is that we will have many more agents that PA, higher resolution textures and larger maps. So of course we are doing everything we can to constantly improve performance.
