when i start up garrysmod everything seems normal but when i want to use the tool gun half of the explanation box disappears. watch the video.
Happens to me too ever since I got my new monitor and changed the aspect ratio accordingly, I just ignore it.
i didn’t get a new monitor, but what is the aspect ratio, is that how big the screen setting is?
Aspect ratio is basically standard or widescreen.
The RT camera tool has an option that makes a small RT screen in that corner, about exactly that size. Make sure that option is disabled.
Edit: Or wait, maybe it was in the other corner. Well check it anyway.
