I've just got myself a Sapphire Radeon 7970 Vapor-x Ghz edition and after lots of research I decided this was the card for me. I loaded it into my rig last night removing the previous GTX 550 Ti's running in SLI, installed the latest drivers (13.1 I believe) and fired up GW2 expecting maximum graphics settings and a blistering fps!
Unfortunately I was left rather disappointed, with the settings as they were previously (everything on high, FXAA off, high res textures etc on at 1080p), in Lions Arch 25-35 fps and out in the world 50 fps but randomly spikes down to 40 every so often... This seems only slightly better than the 550's.
The machine is running an AMD Phenom II X6 1090T @ 3.2Ghz, 8Gb of Corsair vengeance ram @ 1600Mhz and then the radeon (the rest of the specs are in my sig). When the games running the CPU is running at around 50% and GPU activity is sat at 31% - That seems rather low to me. I tried putting the graphics settings up and switching to supersampling to try and entice the GPU but usage stayed at 31% and the fps took a serious hit.
So am I just expecting too much or should the game be performing considerably better? If so, anything I'm doing wrong?
