Right click gmod in steam, go to properties, set launch options and type:
-dxlevel 85
THen tell me if it works.
I already have that set I'm sure. It's how I can barely function on Gmod.
Same thing for me
I think your processor is too weak to run it
It's been working fine before.
get rid of spidermod. it's a bug. and it causes bugs.
Deleted.
I get this too, Ctrl-Alt-delete and then close task manager and click Garry's mod taskbar icon
Will try that now. EDIT: Didn't seem to work. I ctrlaltdel'd, went to task manager, closed it (though it never went away :( ) and then finally clicked the Garrys Mod Taskbar Icon. Sure enough, nothing happened. Methinks I'ma reinstall. I'm about to go to sleep anyway.
If removing addons doesn't help you'll probably have to reinstall.
Probably. I see no downsides though.
DOUBLE EDIT: Wow, the install only took about 2 minutes.
Triple Edit: God damn. I reinstalled and it still doesn't work. Maybe my processor IS too weak. Can you update your processor on a laptop?
