Around 2 days ago I updated Skyrim and everything appeared to be fine. But then I got this huge lag spike, much like on the PS3. It happened at the Dark Brotherhood sanctuary and was incredibly bad but it did NOT jam the game and the game went back to normal. Not sure if this has to do with the update or not. Skyrim is installed to my hard drive and I'm around 45 hours into the game. I DO have a lot of save files, but I see no delete option for them.. I'd mainly delete my really old files. I have 2 files for my current playthrough, one being a backup at almost 1000 saves.
How can I reduce lag in Skyrim? It doesn't appear to be in any other games I play..
