Slow and Jerky Graphics
I just posted a similar thread under Windows Media Center concerning the playback of recorded TV video. I triple boot Windows XP Pro 32 bit, Vista Home Premium 64 bit and now Windows 7 RC1 (build 7100). I have experimented with different graphics cards and different drivers. In Windows XP my playback is without fault. In Vista & Win 7 it jerks.
I also noticed today that an executable slide show had the same symptoms. Then I went to a folder with just pictures in it and tried to view them using the default Windows 7 picture viewer, and it was *way* slow loading each picture, showing the "loading" icon on each picture before it finally came up. I then booted back into XP and brought up the same folder in Windows Picture & Fax viewer. In XP you can thumb from one picture to the next almost immediately. These are 1.5 to 2 Mb files direct off my digital camera. Vista and Windows 7 display the same sluggishness. My Vista install was originally 32 bit. It was slow too.
Does anyone have any suggestions?
