When I mean Power Supply, I didn't mean by the temperature of your computer, but that is indeed rather a bit high. ^^" Still, it would be great to know what Power Supply you have on your computer. (Because sometimes Power Supply does not have the amount needed to maintain a stable state, which
may explain the high temperature inside your computer.)
As for GvG, it lags. Regardless of what Guild Halls I'm playing on, it somehow lags. So I presume that is normal.
Resolution does affect FPS by a huge proportion, you probably didn't notice much. I believe that you never really thoroughly test different resolution at different situations. (Such as going through an intense battle with different resolution) I've tested it, in comparison, 1280x1024 and 1024x768 is very noticeable when in combat and especially in GvG. You can expect heaps of 'jiggles' and decrease in 20%-50% decrease in performance when in Combat. And if you want to know how I test this, I have 5 different computers with different specification. (From Low Ranger to High Range, you name it
)
As stated in my previous post, Nightfall contains graphical tweaks that will affect performance even on mid-range computers. There are bump maps on landscape (Presumably only on rocks, bet nobody noticed it), high resolution textures used on NPC Heroes and couple of Bosses, and refracting instances. (Perhaps more than just those graphical tweaks) But you did say something right, GvG shouldn't have carried the FPS problem through NF, since in most cases they are designed way before it was released. However, it still somehow lags regardlessly.
Ok, another solution... Have you tried updating your graphic card drivers? I would assume you already had, since you swap around your graphic card quite a lot of times.
