In Skyrim - Acceleration Layer Mod thread you wrote: "The game is almost seemless for me on my ancient rig. I have an X2-5000 with 2gig of ram and play on high with 0 stuttering and 0 crashes in over 250 hours of gameplay."
What resolution you play your game at and at what settings? My machine's specs are a bit better than yours (I mean no disrespect) and I am unable to play it in high!
