Hi,
I’m not sure this a is a Black Mesa problem or a Steam problem, but whatever, here is what happenned.
First launch yesterday, everything went well, the game started on a lower resolution in 4 : 3.
Then I went to set up everything in the video option, resolution (1366x768, instead of my native which is 1920x1080), played the game a moment, and still, everything went well.
When I came back today to play another round, I could not start the game because of this error : Failed to create D3D Device.
I’ve found out that if I wanted to start the game, I needed to start it with my native resolution (1920x1080) otherwise it gives me the same error.
The fix I’ve found it’s to set launch options with my native resolution : -w 1920 -h 1080
With that, it works.
Then, if I try to change the resolution back (in-game), then leave the game immediatly (without playing), then removing the launch option, I can start the game again without problem.
But if I play a little bit, then leave the game, then removing launch option, I won’t be able to start the game because of “Failed to create D3D Device”.
Well, I hope it’ll help some people while waiting on a fix. Oh ! And btw, this game ROCKS !!!
