I can't playback my timeline in my project, I used to be able too, but now I can't; the project is way lighter then before since there no more audio in it, only video.
I push SPACEBAR and CTI doesn't move, scroll and image can barely keep up on program window.

I cannot works on my system which I newly reseted and upgraded to be able to work more smoothly :(
Sounds like the system should be able to handle most of what you could throw at it.
Let's take a step back and see what has changed.
I'm assuming that you did not have this issue, with your previous configuration. Is that correct? What parts of the system were changed/upgraded? What is different with your current setup? Those *might* give some clue, as to where to start looking.
