Why do you work in such big resolutions? It is totally unnecessary.
Because I use my own art, which is scanned in at very high resolution, also SA screenshots need to be Hi Res or they suck, and thirdly- because I can, and the images I work with will kill other computers.
The software I use pixelates it if I resize, however ive just aquired photoshop cs3 so i will see how that goes.
