Diablo 1 HD Hellfire Mod | Awake

Hi.
I was able to install and play Diablo 1 HD/Beelzebub mod.
My first impression are amazed, since I have never thought that was possible.
But, while I play in the first dungeon, my game freezes, stop to respond and for some reason it make my monitor blink a black screen, when it backs to normal, shows a triangle yellow sign with a "!" on the small icons and shows the following message: "The video drive stopped to respond and restored itself - The video drive ATI Radeon Family stopped to respond and restored itself with sucess".

PS: I dont know if this is true, but it look like to happens always when my dungeon map is open, I can spent a lot of minutes in town without any problem, but when I go to the church and I need to open the map, after a few steps and monster fights, it happens. Btw, I have not tried without open the map, because I think it is just my imagination.

Sorry any mistakes with my english, not my native language.

Must be a bug with the driver version your computer is running.

I don't remember ever having this problem with this mod, and even though I'm certainly not one of the biggest players around, I did play it for quite a few hours, with a Radeon graphics cards.

So... did you try updating your driver?

Maybe also try to start the game in some compatibility mode.

Btw. using Radeon too.
Having very very few graphic glitches here and there.
But the game is running just fine besides that.

Thank you for the answers!

Kirase, I will try play a while in some compatibility mode, thanks for the tip!

Constance, my video's driver version is already up-to-date for my coinvinience. I am happy to know this game works with most Radeon users, I just need to know why in my case it glitches.
