Steam, all DLC, Win 10 64 Bit, AMD 1800X, 64 GB RAM, C Drive is 8TB SSD and I run Steam on it/load games from it.
The first time or two I loaded the game I just ended up with a black screen before anything but the credits. After a reboot I managed to get to the settings, with it set to windowed mode. I’ve a 4k monitor. Ultimately I got into the start. Chose the easier difficulty and got into character creation rather than taking a pregen. But it just stopped accepting mouse clicks after awhile.
I could switch between several portraits before locking up. Or if I chose one, I could go farther and flip some aspects of a character before nothing would move, though often I’d still get audio feedback as if the engine were still responding.
Sometimes I could CTRL-ALT-DEL to Task Manager or ALT-TAB to quit the program but a couple of times I just had to reset my PC.
