1. First you need Notepad++: https://notepad-plus-plus.org/repository/6.x/6.9.1/npp.6.9.1.Installer.exe
   
2. Second once installed you need to go to Plugins > Plugin Manager > select HEX-Editor and install it
   
3. Now navigate to your game files (Right click the game in steam > Properties > Local Files > Browse Local Files)
   
4. Click on the BIN folder
   
5. Right-click on xgcore.dll > select Copy > Paste this file in the same window to create a backup
   
6. Right-click on the xgcore.dll > open in Notepad++ (or drag it into the notepad++ window)
   
7. Click Plugins > HEX-Editor > View in HEX (if you fail later it is because you aren't in 8-bit mode, you can set this in the options for the plugin)
   
8. This next step is for 3440x1440 (2560x1080 will be at the end)
   
9. CTRL+F and click the Replace Tab
   
10. Paste "39 8E E3 3F" in the Find field and "8E E3 18 40" Replace field (Don't click anything yet, and you obviously do not include the quotation marks)
    
11. Click FIND to find the first entry (make sure your cursor is at the top) and replace that entry. You do this for every entry except the one shown here: http://i.imgur.com/r6m9dLx.png
    
12. It is important you change all found entries except the one in that picture (it is the only one that doesn't terminate on a single line)
    
13. Now click Save and close Notepad++
    
14. Launch the game
    
15. Enjoy true 21:9 gameplay with no black bars

If you experience a crash it is likely because you changed the wrong line as my game is running perfectly stable: http://i.imgur.com/ZIJsp8R.jpg & http://i.imgur.com/gLt0x7G.jpg

Note: For 2560x1080 use "26 B4 17 40" as the new value instead.

Tip: Sometimes (not sure if it is related to this edit or not) the game will launch and not appear to be running, but it is in your task bar. You can alt-tab over to it to get it as the active window and then press ALT+ENTER to fullscreen it (may have to hit it twice). This is probably just a game bug that occasionally happens though and has nothing to do with the edit.

NOTE: This is just the concept for finding FOV and modifying it. I have no interest in troubleshooting this or determining what works and does not. Use this guide at your own risk. For understanding how to modify the below and what, refer to the other page in this guide.

FOV for games can be found in hex in one of the game's files (probably xgcore.dll like the resolution). Format will most likely be in IEEE 754 which is comprised of four hex pairs (just like resolution in this game and most games).

• Example: An FOV of 60.0 would be "42 70 00 00" in hex.

Typically this is formatted from right to left game files. So "42 70 00 00" becomes "00 00 70 42" in hex.

You can use a IEEE 754 calculator to get your fov value into hex (ex http://babbage.cs.qc.cuny.edu/IEEE-754.old/Decimal.html). Paste your fov in the decimal field and click the Rounded or Not Rounded button (either works) and look for the hex result under single precision field.

• Example: Instead of hex in this format "ST UV WX YZ" it would be in this format "YZ WX UV ST"

In anticipation of requests for odd/unusual aspect rations I have included a list of common ones below:
