Guild Wars 2

CPU: Intel Core i3
RAM: 4Gb
GPU: ATI Mobility Radeon HD5650
OS: Win7 SP 1 64bit
Driver: ATI Mobility Catalyst 12.8

I have a Vaio notebook. Please note, that I do not have any fps related issues with most of the games. Recently, I only had drops in D3 and SW:ToR, for reasons not known to me. In this matter, I have around 50 fps upon entering the game and after like 10 minutes or so, my FPS drop to around 15, with a peak of 25. I’ve been monitoring the temperature of my GPU and it stays the same (~70C degrees) at the beginning and in the middle of playing. Overclocking it didn’t help, neither did installing various drivers (Sony has them blacklisted, so I was installing un-blacklisted 12.8 drivers and the 11.12 drivers from Sony support site, no changes in performance). Of course, I performed a clean installation every time. I also had my HD defragmented and the registry cleaned, along with any system caches, etc.
Moreover, there is no or very little (2-3 fps) difference between the highest, auto and the lowest graphic settings. At the moment I play on highest textures, HD character models, best texture filtering, depth blur and everything else on lowest, but changing it to even lower does nothing at all for my fps.
