im about to try this cuz im having this issue XD alt tab takes what seems like forever, zones take like a good 30 sec to load, plus wow does this odd thing where it will randomly alt tab itself >.>
i used to run 90-100 fps ive dropped to like 60 since this started recently.
WoW is hitting the page file often enough that it becomes a problem. Don't have a flash card reader either...
Probably just time for a new PC. DO NOT play WoW with 4gb of ram.
Yeah well, you have 4 gb of RAM. WIndows 7 eats 1 GB. Browser with ~6-15 tabs eats another 1 GB. Now, WoW have to get some RAM, and I guess it needs 2 GB ram as bare minimum. So, when you play WoW, anything else is dumped into pagefile to free RAM for wow. When you alt+tab to, say, browser, it uncovers browser's data from pagefile, and instead dumps wow's data to pagefile, this requires a lot of HDD reading/writing, which is awfully slow compared to ram read/write speeds; that's why everything is slow. Now, all you did is made a RAM disc out of your flash drive, which added a lot of "RAM" to your system, that's all.
But if serious, you should just buy yourself another 4 gb of ram, it costs less than one dinner in restaurant nowadays.
No more time wasted in WoW.. still reading this awesome forum, though
Started up one of my old computers that was used in wrath and could hardly run it with about 30fps with about 1.5gb of DDR1, had no issues alt tabbing.
