I've just tried the same with Neverwinter, which was the only other game I have installed on the laptop. I get a similar performance drop when playing full screen, so for the time being I'll assume it's a fairly common driver issue and will be fixed in some later version.

I will do the same for now. I had some issues doing a clean install last time I tried, so I'm not quite ready for that yet. I'll try with some other games as well and see if they have similar issues.

I haven't played Guild Wars 2 specifically, but CPU does become an issue for some other games in the genre once too many people are in a single area. Have you tried playing with the graphics settings at all? If lowering them doesn't increase the FPS significantly, then CPU being the bottleneck would be very likely.

I have a M17x R4 with 7970M. Last week I upgraded to Windows 8.1. After the upgrade, I lost my dedicated graphics until I installed these drivers (AMD 13.151). However, now I'm seeing a very strange performance issue. I was trying to play Rift on the laptop, but it was performing even worse than it was before I reinstalled the AMD drivers. I was getting about 2 FPS on settings that were previously fine for the laptop. After some experimentation I figured out that the performance is fine when I run the game in windowed mode, but it is terrible when running full screen. I realize this is a pretty specific set of circumstances, but has anyone seen something similar, or does anyone have any suggestions on what I could try to resolve this?

Thanks for the update. It appears the European Dell website is lagging behind. A12 was still the latest version there.
