Windows 7 and 8.1 Support
UPDATE 1:

FOR WINDOWS 8.1- i HAVE HAD ZERO ISSUES RUNNING IT, I STARTED AND PLAYED THE GAME WITHOUT HAVING TO CHANGE OR MESS WITH ANYTHING.

FOR WINDOWS 7- INITIALLY I COULDN'T GET IT TO START AT ALL, I WAS ABLE TO GET TO THE MAIN MENU BY BYPASSING THE LAUNCHER WITH THE STEPS SHOWN IN THIS VIDEO. WITH THE VIDEO BELOW I WAS ABLE TO GET TO THE MAIN MENU BUT I WAS NOT ABLE TO START THE GAME, WOULD CRASH AS SOON AS YOU HIT STORY OR TRY TO CHANGE SETTINGS. I HAVE BEEN SPEAKING TO A COUPLE PEOPLE ON THE FORMS WHO CLAIM TO HAVE BEEN ABLE TO GET IT RUNNING ON WINDOWS 7 BUT I HAVE NOT BEEN ABLE TO DUPLICATE THE RESULTS ON MY RIG.

CONCLUSION: IF YOU HAVE WINDOWS 8.1 I WOULDN'T WORRY ABOUT IT. INFACT IT IS RUNNING BETTER THAN MAFIA 3 DID. IF YOU HAVE WINDOWS 7 I WOULD CAUTION YOU IN PURCHASING IT. I AM GOING TO KEEP LOOKING TO SEE IF I CAN FIND A WORKAROUND FOR WINDOWS 7 BUT TILL A RELIABLE WORKAROUND IS FOUND I WOULD NOT PURCHASE IF YOU HAVE WINDOWS 7. WINDOWS 8.1 ON THE OTHER HAND IS FINE.

------------------------------------------------------------------------------------------------------------
UPDATE 2:

ALSO WANTED TO ADD THAT I THINK THERE MAY BE SOME MISSING FILES IN PLAY THAT MAY BE CAUSING THE ISSUES WITH WINDOWS 7 COMPATIBILITY. I AM STILL LOOKING INTO IT. BUT IT IS VERY HARD TO SAY WHAT SPECIFIC FILES ARE NOT COMPATIBLE OR MISSING. I STILL HAVE NOT BEEN ABLE TO GET THE GAME RUNNING ON THE WINDOWS 7 COMPUTER. BUT THE WINDOWS 8.1 COMPUTER IS WORKING JUST FINE I HAVE ALMOST COMPLETED THE GAME WITH IT. WILL UPDATE AGAIN IF I LEARN ANYTHING FURTHER.

-----------------------------------------------------------------------------------------------------------

UPDATE 3:

WE HAVE ACHIEVED A SOLUTION TO WINDOWS 7. I MARKED THE CORRECT ANSWER BELOW. I HAVE TESTED THIS OUT ON MY SYSTEM AND ALSO ON A FRIENDS WINDOWS 7 COMPUTER AS WELL AND THE SOLUTION SOLVES THE CRASHING AND THE GAME NOW PLAYS NORMALLY. WE DID IT, I WANT TO THANK EVERYONE WHO CONTRIBUTED TO COMING UP WITH A SOLUTION. WE HAVE SHOWN WHAT WE CAN ACHIEVE WHEN WE COME TOGETHER AS A COMMUNITY. WE NOW HAVE COMPATIABILTY WITH WINDOWS 7 AND WINDOWS 8.1.

I got it working on Windows 7. I re-wrote the directions because some if it was difficult to understand. I am pasting them here:

FIRST~
Navigate to C:\Windows\System32 and copy xinput1_3.dll to a different directory.
Rename newly copied xinput1_3.dll to xinput1_4.dll.
Move newly renamed xinput1_4.dll to <path-to-game>. In this case, Local diskC\Program Files(x86)\Steam\Steammaps\Common\Mafia Definitive Edition.

SECOND~
1.Download dxvk-1.7.1.tar.gz from here https://github.com/doitsujin/dxvk/releases
2.Unpack dxvk-1.7.1.tar.gz and copy all dll libraries from the x64 folder to the main directory of the game.
3.Now go to the Documents \ My Games \ Mafia Definitive Edition \ Saves folder Edit the launchcconfig.cfg file with Notepad and change it to: 0 0 0
4. Open videoconfig.cfg and change to: -6 0 1920 1080 0 0 0 0 if using a 1080p monitor OR change it to: -6 0 2560 1440 0 0 0 0 if using 1440p monitor.
5. Run the game via mafiadefinitiveedition.exe in the directory, not via the original launcher shortcut.
In options, keep it at Windowed mode! .. but change the border option to "no borders."

same here. also i still like to play some older titles and they are not all supported with win 10. so i can keep this as my old win 8.1 pc and buy a win 10 pc next year when they finally release DDR5 and stuff.

Yeah, the only game I have not been able to play because of being only windows 10 was Sea of Thieves. I just recently played Destroy all humans remake and it gave me no issues at all despite being windows 10 as the min spec. Sadly i wont be able to play cyberpunk 2077 because that game is direct x12 only which isn't supported by windows 8.1.

For other games like cyberpunk 2077 I agree. But this game literally is using the Mafia 3 engine with direct x11. So I really dont see why it wouldnt be able to run in older OS. But we will see when it releases. I just dont want to upgrade till I get my new computer next year.

Many games in 2020 are saying they are Win10 exclusives. However, if the game uses DX11 or Vulkan API it's almost guaranteed to be working on Windows 7 and Windows 8.1, just without 'developer support', whatever it means. This is fine with me as my GPU isn't beefy enough to for ray-traced games anyway.

Honestly, in 2020 I stumbled upon only one game where developers intentionally cut Win7 support despite being Dx11 game - The Riftbreaker demo/prologue.

Unknown as for now, but somewhat unlikely.
Mafia 1:DE is built on Illusion Engine used for Mafia 2 and Mafia 3 (actually copying many things from Mafia 3) and they all are working on Windows 7.
Also, they list GTX 680 as a GPU required to run this game and this is DX11 GPU.

You don't have to format if you wanna update. You can update to Windows 10 just like any regular update (the ones you don't get anymore). None of your files or softwares will be affected. It's just a Windows update.

It may run on Windows 7. The reasoning for Publishers not listing Windows 7 anymore is simply that it isnt officially supported anymore. It MAY run but don't expect it to and at that point your own fault. Windows 7 being officially listed will become less and less which is normal.

Yeah, but Windows 8.1 hasn't met the same fate as 7, so it's weird that 2K didn't list 8.1 as part of the minimum system requirements.

You can also go legit without formatting and update.
