PRODUCT - Will your products work on CS5 or lower Adobe applications?
The long answer is maybe but probably not ¯\_(ツ)_/¯ .
You will have no problem using the .tif texture images in our texture packs.
If you are running CS5 or earlier there is a good chance you are running a 5+ year old machine and you may experience slow performance with some of our more vector brushes and effects. This will depend on your processing power and RAM.
Earlier versions of Photoshop will not be fully compatible with our 5000px brushes or smart PSDs.
