I just downloaded Gmod two days ago, and when it finished I hopped on, selected singleplayer, and the map flatgrass. During the loading screen I recieved this error:
I have tried everything, (yes, that tutorial on Steam too,) and I’m just wondering if my computer could even * run* Garry’s Mod at all.
Windows XP Home Edition, Version 2002, Service Pack 3.
Pentium 4 CPU 2.40 GHz
2.39 GHz, 1.00 GB of RAM
All help appreciated.
