      With Opera not running fo into your profile folder and delete the three files that starts with 'session' that you find there. Just a heads up, this will clear any webpages that you had open the last time you exited the browser so you wont be able to continue where you left off. Bookmark them before you delete these files if you need them. Does that fix the problem?

      I thought this would be the cause since someone else on here said it fixed it. But when I go into my profile folder there are no files with 'session' in it

        Go to opera://gpu/. Post results. Be sure to use markdown so the forum doesn't gobble it up.

          I'm trying to paste it but not sure how to use the markdown to properly display all of it (it's long). And right now it looks like a jumbled mess when I try to paste it here

            Just do the 'Graphics Feature Status', 'Driver Bug Workarounds' and 'Problems Detected' sections if that makes it easier. Below you'll see my output. Its fairly standard for a Windows machine.

            Use four spaces at the beginning of each line to indicate a block of pre-formatted text, such as code samples.

            Example:

            Graphics Feature Status
            Canvas: Hardware accelerated
            Flash: Hardware accelerated

            Compositing: Hardware accelerated

              lando242 May I ask a question. I have used Opera for many years, but am not a computer expert by any means. I am also experiencing the problems mentioned here. I am not able to find the Opera profile folder to see if I have the files with 'sessions' there! Can you help me navigate there please?

                Opera Menu > About Opera. It says the location of the profile folder near the bottom of the page.

                    Ditto, same problem, except my lags are about 3-5 seconds long every 20-30 seconds. Opera is now impossible to use.

                        Did you try the deleting of the sessions files?

                            Read the first reply to this thread, that should cover it.

                              When I go to the AppData\Roaming\Opera Software\Opera Stable there are no files in that folder with "session" in them
