Well, I have no idea why, but I cant create things in photoshop in a bigger than than 1025x480. Its really laggy, for example if i were to use the smear/smudge tool it would take 7 seconds later for it to finish a simple smudge, I dont have a bad computer either.. :S
As you can see from what I made I'm a HUGE space fanatic, I might not be good, but I'm getting there I hope..
Maybe sometime you can do a video on your entire process to ease my pain staking time in photoshop learning things solo.
Well, actually I can, but the free time is needed very much... SA takes almost all of my free time and there is one important project I do nowdays, but as I said, maybe... Anyway I know that this is silly question but... Do you have original version of Adobe photoshope ? If you do, than there can be some problem with you RAM memories (working too slowly aso.) or software problems- you can try reinstalling it at least.
Hm... It seems to be very strange... I think it has to be some software error. that something is not compatible with it because the PC you described, it's far more better than the my one, which doesn't have any problem such as this one...
