T4 MP not launching properly
When launching T4 MP, can hear the menu music but shows up on the screen. Not even a black screen, it just shows up as a transparent window in the taskbar.
T4 ZM works fine however. My guess is that when I downloaded custom zombies maps it messed with the MP client, since I noticed the issue sometime after downloading the modded maps. However deleting the mods doesn't seem to have fixed the MP issue nor repairing the T4 installation.
Try copy pasting this command in the bootstrapper cmd window and see if you can alt tab into the game again:
r_fullscreen 0;vid_xpos 0;vid_ypos 0;r_noborder 1;vid_restart
Wow I guess it was that simple. Thanks for the help.
@KaseyMoxie World at War is an old game and fullscreen mode has issues (+ Windows 10 fullscreen optimization miight not make it better) so yeah windowed borderless (r_fullscreen 0) is highly recommended. It will avoid crashes when using alt tab too.
