I have used the tutorial Hex editing for NVidia surround and I have had zero problems in the game. I have GTX 980 Ti in Sli.

First I took my resolution and created the Hex code......I use 5760 x 1200 so 5760/1200 = 4.8
So, the correct code to enter into HxD is: 9A 99 99 40 (this IS the correct order for the digits and letters)

open HxD, drag mgsvtpp folder from steam/steamapps/common/MGS_TPP and correct the code line, save.

My game runs perfectly in Surround, HUD is perfect, no marker issues, no other corrections needed.
My game version on the start screen shows 1.04

Sorry if this is redundant, but I had a hard time finding mgsvtpp(exe) file so I thought I'd include the path here.

Cheat Engine table:

mgsvtpp_1041.7z

First value should be changed
from
F3 0F 59 0D DC 0D FD FE
to
F3 0F 59 0D E0 0D FD FE
this fixes marker position.

Second value - 64, is size for marker and some ui elements.
Proper value should be calculated by formula:
64 * ((width/height)/1.77777)
For example, 64 * ((6000/1080)/1.77777) = 200.00087
So, 64 should be changed to 200.00087

Third value should be changed
from
F3 44 0F 5E 81 0C 01 00 00
to
F3 44 0F 59 81 0C 01 00 00
this fixes sonar effect.

Fourth value should be changed
from
F3 0F 5E AA 0C 01 00 00
to
F3 0F 59 AA 0C 01 00 00
this fixes wind effect in the desert.

FOV Tool:

MGSTPP_FOV_1_041.7z

Grrrrr.....

The darned patches/updates FUBAR the settings.

Since last evening, I guess there was some kind of update.

I simply revisited the .exe file and placed it into HxD and re-edited my settings.....all good.

Did the EXE/codes change AGAIN today? My game is crashing now even though jackfuste's codes for 1.041 were working perfectly yesterday.

EDIT: Can confirm when I use cheat engine the codes are no longer the same as what Jackfuste posted yesterday, here is what I'm getting now instead:

1. 28 C3 0F 28 CA 0F C6 C3
2. 64
3. 0F 59 D0 0F 55 F3 0F 58 D4
4. D2 E8 BC BA 8B FF 90 48

and the FOV multiplier now has a default value of 0.
