When i make sigs twoards the end of em everything starts kinda lagging when i try to add stuff. i think its cause my graphics card but i got a new xps. Anyone know how to adjust my card settings to speed it up?

this is not to do with the graphics card, its to do with the RAM, basically it has to do more things to more and more layers, and it is quite common, try merging layers that you dont need to go back to!

This is pretty obvious as kirsty said, try making a smaller size document and saving it more frequent.
You can also group layers to sort things.

tiight thanks guys
