You obviously do not understand the purpose of Safe Mode. It's a troubleshooting environment and disables many non-essential features in addition to performing other maintenance functions. Of course things that are graphics intensive will run more slowly because hardware accelerated graphics is disabled. I'd recommend reading the documentation regarding Safe Mode.
re "You obviously do not understand the purpose of Safe Mode"
Well I understand the purpose of safe mode and there is a massive problem. While trying to clear some plist and cache data to resolve an issue with preview. For some reason preview will only open the same image even after deleting it from my machine...no matter what I am trying to open. Preview will then become unresponsive and hang.
The problem can only be resolved by booting into safe mode then back into normal mode.
Checking activity monitor while booted into safe mode reveals more than 14gig of memory allocated as "wired"(I have 16 gig of memory) after the memory required by the OS is allocated this leaves programs a small portion to run in.
opening the applications window takes 10 seconds in safe mode and that is NOT normal.
Do you have any idea how the wired memory is allocated and how to determine why the core would require 14gig of memory ?
