At the main menu screen in fullscreen mode at 2560x1600. The screen flicks black and I sometime receive nvidia errors reporting that my," video card has stopped responding and has recovered". The mouse pointer is visible on screen and can be moved about.

At the main menu screen in windowed 1024x768 (debug purposes, fiddled with the LoG config) the game window flashes white intermittently, flickering pixels. Attempting to play the game results in shocking fps. Tried again after a reboot and the window stayed black once the LoG loading screen finished.

In both cases the music plays fine regardless what is happening on screen.

Getting late here so I can't spend the time to screenshot/dxdiag.

System specs are: intel i7 960, 8gb ram, nvidia gtx 580 (295.73 drivers), windows 7 64bit (with latest updates). Currently able to play Tribes: Ascend, Left for Dead 2, Dota 2, Witcher 2, Diablo 3 and Arkham City flawlessly in maximum detail at 2560x1600. I'm using the download from the humblebundle website.

Turn on vsync.

That'd be VerticalSync = 1 (default) in the config file? Can't get to it in-game anymore as the window goes black moments after the main menu appears.

Not sure about the config file (will wait for a dev to reply to that), but you could probably force vsync on through your video card control panel settings.

In the config file
"verticalSync = 1" means vertical sync off.
"verticalSync = 2" means vertical sync on.
"verticalSync = 3" means triple buffering.

Could you try setting it to value 2 and see if it helps?

Tried "verticalSync = 2". Seemed to make the main menu more stable (no instant black screen when running fullscreen). Flickering pixels still as noted above still occur. I can click Load Game/Options/Credits and get what is expected but New Game/Quit Game options don't respond (the mouseover highlight works though).

When running in windowed mode the window is black except for the flaming torch which is animated and the glow/smoke above it. No main menu is visible.

As noted on another thread there is an unfortunate bug with 2560x1440 resolutions which causes the topmost menu entry to act strangely. You can use arrow keys and return keys to navigate the menus until this problem has been addressed by a upcoming patch.

Tried 1024x768/full screen and was able to start a new game. Screen went black. Alt tabbed out and back in again to find the introduction text scrolling away. Bypassed that and black screen again. Alt f4'd and noticed an nvidia 'not responding' error fading away from the system tray.

I've also tried fiddling around with the nvidia control panel options (disabling AA, forcing vsync) but didn't have any luck.

I'll be back in about 24 hrs to have a look about the forums to see if there's any info or similar problems. Thanks for the assistance so far

A friend of mine had a problem with the screen being black and only showing the torches. It had to do with Crossfire/SLI, and I think he solved it by turning that off.

That's actually caused by forced anti-aliasing from a graphics driver software.
