Firstly, sorry for my English.

I have problems with running the game. I try to run it with desktop icon and with konsole (console program for KDE/Plasma5).
This is console input/output
[code=bash]
# It is working directory of game I have read from desktop icon
cd "/home/slawomir/badware/This War Of Mine"
# Now I start the game with command I have read from desktop icon
"/home/slawomir/badware/This War Of Mine/start.sh" ""
Running This War Of Mine
GLX_EXT_swap_control not supported, unable to set vertical sync.
Extension EXT_texture_compression_s3tc not supported. Shutting down the game.
# Now I do above, but without empty paramater
slawomir@linux-jdzf:~/badware/This War Of Mine> "/home/slawomir/badware/This War Of Mine/start.sh"
Running This War Of Mine
GLX_EXT_swap_control not supported, unable to set vertical sync.
Extension EXT_texture_compression_s3tc not supported. Shutting down the game.
[/code]

Looking to output I got think the reason of game not running are my Intel GPU driver (mesa), but I run game previously normally and I didn't update Mesa. As I know, the s3tc texture compressing method are now patent free, so It was included in mainline Mesa library.

Ok. I solves this problem by:

force_s3tc_enable=true /home/slawomir/badware/This\ War\ Of\ Mine/start.sh

This solution I found on this site:
https://askubuntu.com/questions/56379/is-there-an-easy-way-to-enable-s3tc-on-intel-graphics

There's also another solution: Install libtxc_dxtn, but this solution won't work on my system.
