Choppy Windows in Windows 7?

Heres what fixed the choppy windows for me
Instructions:
Press [Win] + R or take the RUN option from the start menu.
Now type regedit there and press Enter Key to open up the Registry Editor Window.
In regedit go to HKEY_CURRENT_USER\Control Panel\Desktop
In the right pane, right click on MenuShowDelay and click on Modify Type in a number between 0 to 4000 [400 is default, I use 1] for how many milliseconds you want the Menu to wait before it opens. Typed 1 in the box and no more chop just smooth sailing... I posted this because it blothered me and I just found the solution had to share it...

I don't know if this will help. I had choppy video play back in google Chrome, Internet Explorer, Windows Media Player. I got windows media player and google chrome to play right without choppiness by disabling flash player. First I typed this into my web bar, chrome://plugins/ , next I disabled Flash. Flash (2 files) - Version: 11.1.31.203 (Disabled), Shockwave Flash 11.1 r31. I thought this would not let me watch videos anymore. It didn't however, videos on youtube worked perfectly in any quality, i used to get a lot of choppiness in 320p, I would change it to 240p and it would work sometimes. Now however i get perfect playback in Chrome and Windows Media Player. Sorry if there are any mistakes in my text, English class was never my strong suite.
