I recently upgraded to Windows 7 Ultimate (without reinstalling, an actual upgrade) and now I'm experiencing some really annoying mouse lag in Chrome. It seems to happen most often when there is a Flash element on the page, though that's not always the case.

I have a Windows Experience base of 7.5 (I just re-ran it), 7.7 in desktop and gaming graphics, and Skyrim still runs fine. I ran an Intel chipset update and re-installed my Catalyst drivers (I uninstalled them first), and I don't have any available Windows Update. I've also re-installed both Chrome and Flash, and I've disabled all of my Chrome extensions. Nothing has helped.

What might be causing this very annoying issue, and what might I do to fix it, short of reformatting?

Thank you.


Solution 1:

It seems that you have built-in Chrome's Flash enabled. It may have one/two versions that will conflict with the default Flash. Therefore they will cause lag when viewing Flash content.

In order to use only the default Flash do the following:

  • Type chrome://plugins/ in Chrome's address bar
  • Check for Shockwave Flash versions that point to Chrome's folder. Disable it/them.
  • Default Flash (pointing to System32) should be enabled.
  • Restart the browser and you should be all set.

Watch this video from other device apparently. It shows what I wrote above.

Solution 2:

I've also experienced weird issues with Chrome when the Shockwave player was present on a page. I disabled Chrome's Shockwave/Flash player and use what's installed on the machine, because sometimes they conflict. You should try disabling Chrome's built-in Flash player.

Mike,

  1. Disable all flash plugins in Chrome
  2. Close all web browsers
  3. Uninstall both Flash and Shockwave
  4. Open the Services snapin. Find the service "Tablet PC Input Service". If it is running stop the service, then change the 'Startup type' to "Disabled". Click OK. (Ignore this step if you are using a tablet PC)
  5. Launch Chrome go to ABOUT:FLAGS and enable GPU compositing.
  6. Close all web browsers
  7. Reboot
  8. Launch a web browser other than Chrome and install Flash (and shockwave if needed) from Adobe's website.
  9. Close all web browsers (this is only because some browsers cache some writes)
  10. Launch Chrome and verify the flash plugin installed correctly.

Don't skip browser closing/reboot steps! This will resolve your mouse lag. It did for me.

Afterthought: if using any OEM or 3rd party mouse software with a USB mouse verify update rate is greater than 300 Hz (this won't fix the problem, but can hide it). MouseRate7 and other utilities can do this.
