Not sure why this is, but my computer runs EXTREMELY slow after quitting StarCraft 2 after playing for an extended period of time (30 mins+). It takes about 5 mins for it to get back to pretty much normal, but it's never 100% fast like it was prior to launching the game. The only way to get Windows running fast again is to restart the PC.
-- Studio XPS 435 Desktop: Intel Core i7-920 Processor (8MB L2 Cache, 2.66GHz)
-- 4 GB DDR3 SDRAM 1067MHz (4 DIMMs)
-- 500 GB SATA Hard Drive (7200 RPM)
-- 512MB ATI Radeon HD 4850
StarCraft 2 runs fine with everything on High settings...well, the loading screen of the 1st game takes a long time to load...longer than everyone else...and then the first 20 seconds of the game it may be really slow and seems like it's loading a bit. But after that, everything loads fast.
Any ideas? It drives me nuts, as I play SC2 daily, and hate restarting my PC due to it server media to my HTPC (which isn't being used during gaming) - I just don't like restarting.
I'm going to test temps this week. I'm thinking it's more of a RAM issue, although 4GB is enough for SC2 and Windows 7 to run fine. I have other stuff running, but more than enough ram for all of it. And it's a fresh install of windows 7 - no bloatware that came with dell. I normally build my own PC's, so I'm not a noob...but I got an open-box deal on this a few years ago for dirt cheap - otherwise I would've never bought a dell.
I'm a total noob...I had like 1.5GB of free RAM, which I thought was enough, since I've alt-tabbed out of SC2 before, and seen it only taking 600MB of RAM. However, I used a remote monitoring program on my iPad to monitor my PC, and noticed it was taking a LOT more than that. I was running out of RAM and I think it was dumping things to my hard drive. I have things like CrashPlan, Dropbox, Subsonic, Sabnzbd, Sickbeard, etc. running, and Chrome - which was using about 1GB of RAM, so I just closed Chrome down and it worked great - I quit SC2 and things were fast almost immediately.
For those interested in the iPad app I used, it's called PC Monitor and it's AWESOME if you like monitoring things remotely or have a server you need to keep track of.
