Garrys mod hl2 engine error

Ok, hello boys n girls.

Ive been playing “GM” for 8 months and never i had this problem…
One day, me and my friend was going to play, and have some fun on ROLEPLAY.

Suddently i got an “ENGINE ERROR” in the second i joined the game.
So i was searching and searching.
Some people said, try this "-dxlevel 80 “81” " i tryed it, it workd, no more error.
But then i got an other problem, the whole “rp_downtown_v2” map was suddently black.

So i search again they said “Update directx driver, and your graphiccard”
i did, but still is the problem there…

Did it happen once or many times?

It could be a number of things
Try this:

1)Look to see if it happens in other Source Games (Half-Life 2, Team Fortress 2 and others)
2) Try and reinstall Garrys Mod from scratch
3) Removing all your addons
4) Look at your Temps of your computer (Possible Overhear although unlikely)

These are the only things i can think of

Also in DX8 does it run other maps fine or is the problem only with rp_downtown_v2?

Ive done evrything that you said now, and i’ve tried to remove the map, and downloaded it again.
Still having the problem…

And the map is like this forever, sometimes its worse .

Could be overheating aswell… check your temperatures.

hmm how?

Hi there, to check your temp just download a trial version
when its installed and started go to computername and sensor there should all temps be

ps: i got the same problems on the
Directx 9 - Engine error
