big stuuters and freezes

[SEE]

Some of your .ini settings don't match up with example config.ini files I have seen for later Nvidia cards (e.g. I had problems with Effects=2) . These may not be responsible for your probs but pretty sure you will get pointers in that respect.
I hadn't a clue that incorrect 'Sound' settings could cause 'stutters'. I have disabled Hardware Acceleration for the time being and will watch this thread with much interest and see what else can cause the dreaded 'stuts'!
