Thanks for the video. I wasn't having gaming / video issues but I knew that some were - again, specifically after display sleep. If you're not sleeping your computer / display, that most likely accounts for why the card works so well for you.
No disrespect intended, but I've seen multiple posts from you claiming to have a fix for the 550Ti issues. As the title of the thread indicates, we are looking for fixes to the sleep / wake / freeze issue. Unless I am mistaken, you don't have a solution to offer for this issue, or additional insight into the cause of the issue?
I understand that you don't care if sleep / wake works; we do!
And again, no disrespect intended - but 100% of people with this card are having issues, and when people are announcing that they've found the solution, people get their hopes up. They spend time following your directions, hoping that it will solve their issue. There is a good chance that someone will find themselves worse off for having followed your directions (or having made a mistake while trying to follow them).
Instead, it is more helpful (IMO) to attempt to reproduce the problem, and post all the information you have about the crashes / hangs / reboots WHATEVER that take place when you try. Announcing that you've solved it only serves to derail the thread and causes headaches for people who believe that following your directions is going to solve their "Nvidia 550Ti Sleep / Wake / Freeze" problems.
Having said all this... I am sincerely happy that your card is working well for you.
