american truck simulator care package 1.12

- description

The saying goes there are many ways to Reno in this
game quite literally and figuratively when it comes
to modding this game.

Basically this mod shifts the color palette, reduces
the quite pronounced darkness gamma wise and adds a
little sharpening in the mix this is based on an unmodded
game so if you are using other mods that alter the light
or weather you might not get quite the same effect as shown
in the screenshots.

3dmigoto shader tweaks:
- reduce intensity sun shafts
- increase global light day / night time
- reduce green or red slightly globally day and night
- increase presence sky dome by reducing green and increasing blue
- decrease density fog horizon land night and day
= update for 17/01/2021 version 1.12 =
- removed increase light in cabin interior no longer needed
- added dampen darkness night sky dome tweak
- added increase rim light effects road ornaments and cars
- modified increase global light night time better mix from day to night

If you do not like specific tweaks please see 'further tweaking'
for disabling specific shader tweaks.

For reshade:
Press 'F1' in game to toggle reshade shaders on or off
or press 'shift F2' and use reshades gui to toggle

- tested

Tested with file version 1.39.3.3 of american truck simulator
on win 7 / nvidia 1050gtx ti
See screenshot for settings game.

- performance

reshade / 3dmigoto gpu usage 1080p@ ~60fps (vsync)
without - clock 1070hz gpu usage ~80%
with - clock 1320hz gpu usage ~75%
approximately 10% increase (1050gtx ti on win 7)
max gpu: 1772Mhz gpu usage 100%

- further tweaking

If you like you can compare the modified shader, ShaderCache contains
the original shader, to alter values.

To disable specific tweaks open the shader from
the folder 'shaderfixes' with a text editor example:
8d01e16dc982b984-ps_replace.txt

Has a remark on the top line:
// decrease density fog horizon land

So if you do not want that to happen
remove the shader from the folder 'shaderfixes'

253c19c80724faa9-ps_replace.txt

and if compiled remove:

253c19c80724faa9-ps_replace.bin

then restart the game.

All shaders <shadernumber>ps_replace.txt have
a similar descriptive remark.

- tips

Start the game with an other homedir location.
Create a shortcut (.lnk) with your file explorer and modify
the properties to:
"<instal dir game>\bin\win_x64\amtrucks.exe" -homedir "<instaldir game>"
example:
"G:\games\american truck simulator\bin\win_x64\amtrucks.exe" -homedir "G:\games\american truck simulator"
After starting the game a new folder will be created called
'american truck simulator'
or you can copy the old 'american truck simulator' to the new location.
