It's free! So take it or leave it!
But when you work on a game , if you can gain time on workflow , i can assure you it's not something you'll not take attention.
some lag on tools : no thanks : and Gimp 2 is free.
oh, gimp 2 has its lags too at times. it be interesting to see a side by side speed comparison working with images with the same resolution and same size brushes/ effects.
I havent use psp10 yet though so i dont know how much it lags.
