You do NOT need Hi-AlgoBoost on that machine--Having it installed will cause more problems that it will address. Remove it entirely and go from there. I have a similar machine (Windows 7 though) and only 4GB of video RAM and have no need for Hi-Algo Boost, so you shouldn't either. It essentially lowers FPS dynamically based on combat state and panning rate ( when you are turning the camera! )--you're machine is QUITE capable of high FPS during combat without it. It sounds to me like you are experiencing exactly what Hi-Algo Boost is supposed to do, so ditch it if you don't like the effects. Beside, it is intended for use by people with low-end computers that still wish to load up a bunch of graphics mods--you sir, do not have a low-end computer.

I was having similar issues to some in this thread and thought I'd post my findings as I see quite a few people are using PDT to clean saves and having similar issues to what I was experiencing. I came to the forums specifically to see if anyone else was having the same issues. Rather than re-post everything I already posted in the comments section for PDT (Savegame Script Scalpel), I'll simply direct you to the comments section there where you will find a recent post by myself that explains the problem I was having, and the FIX. Please do not take this as me disparaging Savegame Script Scalpel in any way--I think it is a fantastic tool and I highly recommend it. http://www.nexusmods.com/skyrim/mods/53045/?tab=4&&navtag=http%3A%2F%2Fwww.nexusmods.com%2Fskyrim%2Fajax%2Fcomments%2F%3Fmod_id%3D53045%26page%3D1%26sort%3DDESC%26pid%3D0%26thread_id%3D1608508&pUp=1

There are a few fixes for this around the internet (including the IN-DEPTH sticky-post at the top of this forum), but the easiest way is if you are already using the Unofficial Skyrim Patch(USKP). If you ARE already using USKP, then just head to Whiterun and go into the Temple of Kynareth. On the tables along the wall are shrines placed there by USKP--these shrines are there specifically to rinse away these "stuck" physical effects applied to the player. Good luck!
