I’ll open this topic with an image: left is ingame, right is some data
My Computer specs:
Windows 10
Intel i5 2500k @ 3.4ghz (issue occurs at 4.0 overclock as well)
16gb DDR3 RAM
Radeon HD 7970 (Using new beta drivers, problem occurs on rolled back drivers as well)
OCZ-AGILITY4 128gb SSD (Game installation drive, OS is on a Crucial M4)
I am at complete wits end. I am the one who usually helps people with issues of this nature. I have run the extreme gamut of ideas to identify and fix the problem I am having with JUST Guild Wars 2. I am getting >100 FPS in Planetside 2 (a game with legendary performance issues) with all settings maxed in quiet areas, and 40-60 FPS in busy fights. My computer also runs just fine in Diablo 3 and World of Warcraft. An hour long Prime95 test did not unearth any facts either.
I was running around Tangled Depths last night when my frames suddenly dropped to ~5 FPS. I figured it was some sort of antivirus scan so I opened up task manager to find that Guild Wars 2 was utilizing <20% of my CPU instead of the usual 80%+. Figuring a fluke, I restarted the game and watched the CPU usage. Everything up to and including the character screen worked fine. I could rotate my characters, swap between them easily and they would load all nicely and behave. However, the moment I would try to enter the game world, GW2 CPU utilization would begin dipping rapidly, and my frames would go with it.
A full restart of my computer proved fruitless, with the pattern repeating itself no matter what I tried while using the 64-bit client. I tried just about every option and command line available to modify how the game would run. I tried many permutations of graphics options from extremely low (on average a 1 FPS gain) to extremely high (no difference). I tried this same testing on the 32-bit client as well. I copied the game folder over to another one of my SSD’s and tried running the game from there — still ~5 FPS and <20% CPU utilization.
In frustration, I formatted my C drive and did a full reinstall of Windows 10 to rule out any malware present that would specifically target GW2. I installed the latest beta drivers from AMD for the 7970 and started the game with nothing else installed and all options left default. To my dismay, 5 FPS and <20% CPU utilization. I ported to different zones, Divinity’s Reach and Auric Basin to see if it was a zone specific issue (god save the queen) to no avail. I took the next logical step and uninstalled my GPU drivers and removed the 7970 and ran the game on integrated graphics. Predictably the game ran incredibly poorly, but still indicated <20% CPU utilization on the task manager.
My computer is clean, inside and out. Temperatures are not a problem, I do not smell anything burning and my fans are functioning. I have made zero hardware changes recently (what is money? baby don’t hurt me) and prior to the issue, no driver or other software/firmware changes that would explain this.
(Note on DxDiag — I installed the AMD beta drivers after I started experiencing this problem. Before the format and reinstallation of Windows 10 I tried an older set of drivers and that did not help either.)
