Recently got a new computer, so I reinstalled some of my games. However, when I click on play in the HOI3 launcher, the screen goes black and a grey block pops up and bounces around which says "Not Optimum mode Recommended 1600 x 900 and 60 Hz".

Please help me to solve this problem. :sad:

In your program installation directory you will find a file called settings.txt.
Make a backup of the file and then start an editor like notepad++ and open it
you will find the following lines:

graphics=
{
size=
{
x=1920
y=1080
}

Edit the x and y entry to corresponded with you max resolution of your monitor.

Below this entry you will find also other useful graphic settings like fullscreen and refresh rate edit with care.
