I have Windows XP SP3, and I decided to install Internet Explorer 8 last\nweek. It installed fine, and I used it for a week, but my desktop UI speed\nhad become NOTICEABLY sluggish: when I move windows around, there would be a\nwhite "lag" behind them, similar to turning on "mouse trails" for your\ncursor. It acted like I had disabled video acceleration. Also, YouTube\nvideos were jittery and my CPU utilization was very high while watching.\n\nThinking it may have been outdated NVidia drivers, I downloaded and\ninstalled the latest release from NVidia's web site, but the situation did\nnot improve.\n\nI've searched the web and the newsgroups and cannot find anyone with a\nsimilar problem; I found some people complained about sluggish WEB PAGES with\nIE8, but my issue is not that web pages are slow to load, but specifically\nit's a problem with my GUI rendering speed.\n\nAnyway, this morning I uninstalled IE8, rebooted, and now my GUI speed is\nback to normal (fast) -\- I can move windows around without trails -\- so it is\nobviously something with Internet Explorer 8.\n\nMy system specs:\nDell 400SC\nPentium-4 HT 2.8GHz single core\n3 GB memory\nNVidia GeForce 7600 GS 512MB AGP 8X, driver version 185.85\nDual LCD monitors\nWindows XP SP3 with all high-priority updates\n\nThoughts? Anyone?
