Checking in with FPS issues as well. Everything was perfect at release with 100+ fps, within last couple weeks this drops to a steady 30-50 fps with spikes all the way down to 5 fps (mainly it seems when loading distant textures or open/close map). These are all with every setting maxed.
System Specs:
Intel core i7 3930k 3.2GHz 6 core
32Gb DDR3 quad core memory
2 EVGA GTX 680 O.C. in SLI
ASUS Sabretooth X79 chipset mobo(as you can see my system is way overkill for GW2 and I should not be having these issues. I also have no problems with anything else so this IS game related ANet.)
Downgrade is your only chance. I’ll send you a fresh lovely 460 in exchange for your 680s. Just PM me. :-)
throw in a box of chocolates and we got a deal
