I think this RAM should get it's own thread. With 006 after a few minutes i was able to use up about 49%, with the second devel I'm currently at 34% which is much better. I'm trying to keep my test conistant as possible. So w/e changes you made between the two has improved it, but not yet solved it.
Let me know what else I can do to help futher.
EDIT:
I had to reboot after the above test so below is a new test, my box starts up with 16% usage.
Yes with the second devel release ram usage is much better, but scrolling the library really fast up and down 3 times makes the ram spike to about 57% then it slowly starts to drop. When i started the library test, ram was at 27% after scrolling it jumped up to 57% and now holding at 30%.
You think the texture bug is still active? People with 1GB probably would have froze by now.
Great work so far.
