First of all, I'd like to say that there are no words to express how impressed I am with the project and since English is not my native language that makes it even harder

The Facts:
a. I installed Skyrim (non SSE) specifically to play Enderal, so it's 100% clean. I haven't even touched the settings before installing the game.
b. After Skyrim got installed, I installed and updated Enderal to the latest version exactly as described in the various guides.
c. I'm currently playing with one mod (Enderal Gameplay Overhaul) but all the issues being mentioned below happen with or without that mod since I restarted multiple times without the mod just to figure out the best combination of settings before I decided to install it.
d. My PC uses a 1080 graphics card with a i7 4790k, 16GB of RAM on dual monitors (different sizes) and game+mod are installed on an SSD. Moreover I'm on Windows 10 Pro 64bit.
e. Regarding the settings, I used 'High' since I never drop below 60fps and haven't touched anything other than audio, mouse sens and the entries that the aforementioned mod requires.
f. Regarding OneTweak, I have no idea when it is on or off since there is no visual indication other that settings changing (does it start on or off?). No matter what state it is though, I will either CTD (no error window, straight to the desktop like nothing happened) or I'll experience a crash with an error window (game not responding etc.).
f2. One thing I have noticed that happens depending upon which state OneTweak is in (on/off) is that videos have no visual and audio stutters (one state) and visuals & audio work normally (another state). Crashes happen anyway no matter if the videos work or not.
g. As mentioned above, crashes will happen no matter what. I read on another thread that it was important how long before a crash happen but I really don't see any stable pattern.. it can happen anytime, indoors, outdoors, without looking at anything specific (to give some reason for the crash), etc.
I have managed to reach 2nd level (just around that 3-wolf battle in the beginning) and I just love what I'm seeing ..and what I'm discovering

Please tell me there is hope for me.
