I already did that, based on your advice in another topic from someone else experiencing a similar problem. Thanks for that, by the way.
Edit: Did some more testing, and my original hypothesis below appears to have been slightly off. I've corrected it now.
1) When I met Talana, the game consistently freezed on the loading screen when trying to load the scene where you play as a dragon for the first time (the scene between meeting her and meeting Damian for the first time). Turning all graphics options down to their lowest made this go away. I'll try lowering them one-by-one the next time I play to see if I can pinpoint the problem.
This appears to be related the "Dynamic Geometry Distance Rendering" setting under the graphics tab of the options menu (but that setting isn't the sole culprit; see next paragraph). If I set it to low, the next scene loads just fine; anything higher causes the game to freeze while loading. I can have all other settings maxed out and the scene will usually load, and no matter how low I set everything else, setting this to medium or higher will cause the game to freeze while loading.
However, even with DGDR at low, the scene doesn't always load. If I've just started up the game, it will, but if I've been playing for a while (or even just had it open on the title screen), it won't. So there may be some sort of memory issue as well. But the DGDR setting is definitely involved in some form or another, because the scene will *never* load if I don't have it set to low, even on a fresh restart.
I should also note that I have no problem with any of the other dragon sequences in the game (although I haven't played through FoV on this computer yet), despite playing at maximum settings. Whatever the problem is, it appears to be unique to this scene.
