Finally. My best run so far after more than 100 attempts, without major mistakes, just some minor annoying ones. And — wow — no crushes during the entire run. I also returned original music. But what really big happened — I discovered a whole new way to skip half of the time of the dialogs by temporarily increasing the maximum frame rate to ~5000 through console and then decreasing in back in the main game (because enemies speed up too). This saves ~5-6 minutes and now this is a world record. I consider this as a fair method because this is an original game function and we already use the rocket jump quicksave-quickload abuse and others. Moreover, in other games, like Half Life, playing with frame rate is a significant part of the speedrunning. This technique also adds more fun as I am tired to try to beat previous great skilled champions, pmcTRILOGY and Skillertare, just using the same keys and paths. Now it feels like a new speedrun, especially with these new fast dialogs that were very annoying for sure. At the same time the new fps technique requires some repeats (this is like 20th attempt). Don't forget to quicksave-qiuickload every time you decrease the frame rate back to the normal 50, otherwise the enemies would still be fast (their speed calculates once the game is quickloaded). I also found the rocket jump is easier with fps ~100, not 50-60. Should experiment more, maybe we can fly after all?:D
