Before I say anything, I just want to say f**k off ubisoft

I played Assassin's creed: Odysseey for about 44 hours when it came out so I know that it is not a problem with my computer
I went to play Assassin's creed: odyssey again so I can buy valhalla and try it out but assassin's creed: odyssey didn't work and I tried every possible thing that I found on the internet to resolve this. I am a computer science major so I am well-versed in computers btw.
I thought that Assassin's Creed: Odyssey might be an older game so I bought ACV to see if ubisoft had gotten their [censored] back together but apparently I guess not.
I don't want to sound a whining kid without telling you what I did so people can have a reference point.

1. uninstall and reinstall ACV (obviously as a first step)
2. verified game files before running to make sure that install was correct
3. moved ACV to my C : drive which is a SSD with my OS (it was on my HDD (D: drive) before)
4. uninstalled ACV and ubisoft
5. installed both ACV and ubisoft connect on my C : drive
6. verified game files again
7. updated my graphics card driver to v. 457 (latest one)
8. verified that firewall was not blocking the program
9. went to my boot options and lowered the overlock to normal
10. went into the ACV application properties and clicked "always run as administrator"
11. set the pagefile on both my C and D drives to be "system managed"
12. went into NVIDIA control panel and
    1. set it to "use the advanced 3D image settings" under "adjust image setting with preview" tab
    2. turned image sharpening off
    3. tuned texture filtering - quality to performance
    4. power management mode - maximum performance
    5. threaded optimization - on
13. moved the icon from the folder to desktop
    1. i started getting about 4 errors that some .dll files were missing (which I could see right there in the folder under the application)
    2. I deleted those .dll files.
    3. verified game files again so that the files would be re-downloaded
    4. when I click the application from desktop again it continues to give the same errors stating that .dll files were missing.
       1. the missing files
          1. uplay_r2_loader64.dll, tobii_gameintegration_x64.dll, GFSDK_Aftermath_Lib.x64.dll, amd_ags_x64.dll
          2. after verifying game files, they are in the folder again
14. reinstalled ACV again and verified files

after all this, it is still crashing to where I cannot even see the menu,
Get the hell off my desktop and refund my money

Hey guys. I found something that made my game work. hopefully it makes your game work for you too
follow these steps

1. go to your desktop
2. right click
3. click display setting
4. scroll down to the bottom
5. click graphic settings
6. the scrolldown menu should be on classic app
7. click browse then find acvalhalla.exe and click add
8. then click the icon and click options
9. set to high performance
10. try running the game again as admin

good luck guys

@exaudio this is ridiculous that this is happening to a game that JUST came out. still no response from ubisoft. figures

bump so others could see potential fix that worked for me

@trolsopol yeah I tried every trick in the book so now I am waiting for refund

I ran AC:odyssey for 44 hours with no issue and got to around 88% progression
I can play all other games on high-ultra and played star wars jedi: fallen order on max setting with no issue

oh and I forgot to mention some other things that I did

1. closed all unnecessary background processes from task manager
2. tried downgrading video card driver to an older version (then updated to newest version)
3. trying restoring to a previous point in my system restore
4. lowered settings for the game before i ran it
5. changed the window size to be smaller (windowsize to 0 in the text file)
