So I basically became a part of this fantasy we all share yesterday!
I gotta begin with that I understand that the game is still in a rough phase and all that, but I just want to make clear that I'am not the only one dragging around on this issue.

What I'am experiencing are two types of issues.

1 - The game will drop in FPS at times and have a obvious slower camera rotation due to that. The resolve I've found for this is to alt-tab and wait a bit.

2 - The real issue is that at other times, the game will completely stop responding and when opening the task manager, FF is also pointing out that it's not responding. If I just watch the game instead I end up seeing minor screen changes at rare occasions, as if I was getting 0,001 FPS or something hehe. This takes much longer time to recover from as well. (20-30 +/- seconds)

I hope you're all having a blast though, as I must say that I'm impressed what the currently Dx.9 version of the game is offering on the graphical output front!

Many thanks in advance
