Video now lags after Windows 7 Install under same hardware
Was under the Vista banner until recently with these hardware specs:
OS: Vista
CPU: 2.83 Quad Core
Video: ATi HD4850
RAM: 8GB
HD: 2x 1TBUsing CS4’s Premiere Pro worked just fine. Came to the forums here and saw that people weren’t having too many issues with Premiere and Windows 7, so decided to upgrade after completion of my last project. Finished that up, installed Win 7, and now am experiencing what can only be described as video playback lag.
In a dual monitor setup, if I made the playback window full screen, it begins to chop out. I’m working with AVCHD files, and understand that they’re hard to work with, but in Vista, I experienced no real problems. The cores run at about 50% each during playback. Again, nothing strange. As I reduce the size of the playback window, the actual playback improves. If I reduce it to the size it originally is when docked, playback is fine.
Nothing on my system has changed besides the OS. I’ve reinstalled the most up-to-date drivers for my card, and saw no improvement. Thoughts would certainly be helpful!

This should solve it:
Remove all your ATI drivers, and driver folder afterward and let Windows install its own.

Do I simply go to the folder in Windows and delete the driver folder and everything in it, or is there a process for removing the actual driver?

No, please don’t. That folder contains all your drivers.
Just the driver folder or file for your ATI card.
But try going to control panel > Programs, and remove the driver from there first. Then restart and let windows do its job. That alone should take care of the issue.

This unfortunately did not solve the problem. It must be some problem with Premiere Pro and Windows 7. Nothing changed, hardware or driver wise between my upgrade, and I did not experience this problem when working with Vista.
Something I left out: If I undock the preview window and make it full screen on the second monitor, it lags out. If I make it very, very small, the video runs fine. Leads me to believe that it’s not using the GPU to process the video. I can’t imagine why that would be the case though.
Playing the AVCHD files just off the desktop in media player classic have no problems at all. It’s only within Adobe Premiere. Thoughts?
