Had a mess around on mission 1. I noticed that you can walk during the intro. I hit escape during the prologue skip, the loading screen, and again to get rid of the cutscene all whilst holding forward. Not sure if you need to press esc, but its worked for me so far. Causes Telsia's dialogue to start whilst the Tuvok cutscene starts playing. When you finally get to play you are pretty much at the end of the corridor in a position to turn around and destroy the nodes.
Had a full playthrough of mission 1. Done in a few segments as I'm out of practice with the strafe jumping. Could shave some more seconds off with better movement and gameplay. Before the 2nd generator modulation (7:40 in vid below), I had restarted that section about 5 times. Probably needs testing to see if it was a complete stroke of luck or easily reproducible. Would save a lot of time in future segmented runs.
