Interesting. I go back a save game and everything works 100% normal. No issues at all!
I load the one save game and it's glitch city. So I think just redo the last few steps of clicking the elemental switch things to open the big door to whatshisface.. I do the first two, and then return back to the 'end of time' to fast heal without spending spells, plus I like to stock up on spells....
I return back to the thorny spot in the phantom forest..and blamo...lag city.
So I load it back again---normal--- Go to the end of time.... lag upon my return.
reloaded back to the 'working' area and went from the thorny spot to silverglen...normal. teleported to cyseal and normal--and then the game suddenly quit back to desktop.
Very odd... Just did the same thing again after restarting. This time all normal with the older load games. Until I fast travel to the end of time, or anywhere else it seems...then it's like my crew is running in place. Seems I'm rather stuck as it's not possible to continue on this way. It's worse when I have my crew all in 'line' and then run into a bad guy...Everyone goes into their 'line spots' and it takes forever for them to line up--not to mention can't cast spells like this. Even when the bad guy hits me with anything, I see the impact--and a few seconds later then I see the blood and the effect of that impact.
At this point it's not my computer, as the early loads run fantastic--until I teleport anywhere......I haven't tried to physically 'walk' out of the areas, as that causes the same effect where it cleans up the level and such, so I would expect the same behavior.
