I have an older iMac (Early 2008, 2.8 GHz Intel Core 2 Duo, 4 GB ram, ATI Radeon HD 2600 Pro graphics) and it is running OSX El Capitan. It seems to run other art software like Sketchbook Pro and Mischief just fine but for some reason the Artrage 4 demo seems very laggy. When I use my graphics tablet it gets even worse basically unusable… Does this sound normal? Is Artrage 4 particularly resource hungry? Is there any other solution other than buying a new computer?

Thanks
