Al-right, let's try to narrow this down then. I made a comparison between that PROGRAM folder and the Beta 3.4 files.
Then I placed the files I consider to be most likely to cause the lag in the attached ZIP. So please do the following:
1. Make a copy of your smoother-running Beta 3.3 install
2. Extract the attached ZIP on top
3. Find a heavy test case and let me know if it got worse again
You may want to find a heavy test case that DOES run smoothly before extracting that ZIP.
That way you can use the exact same scenario to check the difference.
