I've bought a powerful machine, Intel I7 720Q with 8 GB RAM and 7200 RPM HDD and Radeon 5870 with 1GB VRAM,
and after installing the new Adobe Master collection CS5 I found out,
x64 are very slow (I have a legal copy!)
E.g. when I open a 3MB file and I'm trying to move it with the hand, or scroll, it is going very slowly, laggy, 10x slower than on my 4 years old machine with CS2 !
Do I have to enable any kind of acceleration or something?
