Wow. Removing Dullahan did wonders on my computer! I came across this because I thought it was weird that Second Life was so much slower on my new laptop, even though both the embedded graphics card was better than the old one and it even had a discrete one as well. But now after taking the dullahan stuff away SL runs pretty smooth even with high settings. The reason I searched was that Dullahan was taking up 60-70% of the GPU, and I had no idea what it was. I still don't know but I can plainly see that SL works better without it.
