OK... a lot of work testing it all out... and stuff.
Status quo: Well, the good message, after some good testing now it all is working properly for me (on a new Windows 10 system)... videos, game engine and resolution (1080P, a little bit streched, just like the original GoG-resolution but more crispy) aswell... The bad message is, it is kinda a bit complicated to solve, because a lot of stuff will have to be solved first.
How to properly fix:
Sure, the RT Launcher would have been the "easy solution" but unfortunately it will simply break the unofficial 1.04 patch, so this is not truly a option to us. So, the best way is trying to fix the videos without touching neither the executables nor the game engine at all. Because if we do we will open Pandora`s box, it may break endless amount of stuff. So i had to find a way "how to make it sensitive but still powerful"... this is somewhat challenging, but thanks to many other users i was trying to get some good input.
Issues to solve: The main issue is simply because for some weird reason the videos are attached to the game engine, and they usually only work with QT (Apple Quick Time). In order to make it work you have to use a older QT file, else the game may become bugged... so the mouse will not work properly anymore, so it will be lagging. I think, it is not easy converting the videos to another format because of the way the engine is attached to those videos. You kinda would have to recompile stuff and whatelse... the work is not just huge, it may aswell break patches...
Improper workaround: As a workaround you could get the CPU to run in a "non natural boosted mode"... so it will simply overpower the software issue by working aproximately 100 times faster than what is truly required. Or you could scale down the mouse-tracking a huge margin and maybe no issue will be detected anymore with a very slow polling-rate (maybe never a issue on notebooks with very slow touch-pads... never tested). But this is simply no good solution for any real gamer system with a high powered mouse... so the software simply will have to work without such issues.
Or you may simply fix those weird QT issues with a older QT backup, so the engine may respond in a more natural way... not going to lag.
Now step by step what to do: 1. Install the GoG game
2. Download those 2 quicktime files with the ending qts and qtp, unpack the folder, move it to the gamefolder and overwite everything when asked: (remove spaceholder) https:/______/mega.nz/file/fhIFGT5b#qaHCS3RcDey6vXo2c6umwogAL5VlZBTI-CVBDz8nmRk
3. Download those updated video files, unpack the folder, move to the gamefolder aswell and overwrite everything when asked: https:/______/mega.nz/file/nzZl2CLY#rl1WOOWFnqinwqnQS3OsKlpRATnXWOJ5KlqXLt4plUo
4. Now download the Voodoo-driver files named "dgVoodoo v2.8", unpack the main-folder and then pick the folder "MS> X86>____" and copy everything inside to the game-folder, overwrite everything when asked: http:/______/dege.fw.hu/dgVoodoo2/dgVoodoo2/
If done properly the game should now be able to be run in the initial "GoG-graphic mode" without any mouse-lag anymore. The video files should work correctly too. So the biggest step is now done.
Optionally: Optionally you can copy the
dgVoodooCpl and the
dgVoodoo.conf to the game-folder and then open the VoodooCpl in order to adjust settings, for example you can remove the Vodoo-Label which is currently apparent on your screen. On the General and Glide tab no need to change anything but on the DirectX tab i would put the resolution to 1080P or any other you may desire and at the same tab you can remove the Voodoo-watermark too.
Basically the game is now using another QT version, altered video files... and another graphic API interface which got a better compatibility with newest systems. However, as far as i can say, the patch or the game itself should not be altered at all... so i think there is nothing broken... not finished testing yet but the possibility for screwing something up is very low.
My game is now looking like this:

Could be interesting to watch, maybe some new patches in the future:
