I've been having some problems eversince I updated from Windows 8 to Windows 8.1 (idk if it is related).
Everytime I start Wolfenstein ET, I get these Lines running trough my screen, horizental lines.
It's quite frustrating because it's there while playing as well. Some maps have a more extreme lines, and in some maps the lines are hardly noticable.
I tried capturing the lines with a screenshot, but they do not show up on the screenshot....
I hope anyone knows how to fix this.
