Strange Performance Issues

Hey all, having some weird performance issues and wanted to check if this is par for the course at this point, or if there is something dreadfully wrong…

System Specs:
AMD FX-4100 OC’d @ 4.0Ghz.
8GB DDR3 1333 (PC3 10666) RAM
HIS IceQ Radeon HD 7870 @ 1100Mhz (Latest WHQL Catalyst drivers (12.8))
Just upgraded from HIS Radeon HD 6750 (Latest WHQL Catalyst drivers (12.8))

3dMark11 Performance before vid card upgrade (Performance setting):
CPU: ~3300
GPU: ~1600
Combined: ~1850

3dMark11 Performance after vid card upgrade (Performance setting):
CPU: ~3300
GPU: ~6900
Combined: ~5550

GW2 settings for all tests (unless otherwise mentioned):
1920×1200
Unlimited framerate
No vertical sync (even disabled it at the driver level to be sure)

Before vid card upgrade in GW2:
Medium-high settings, no AA, some bells and whistles turned off, 20-45 FPS depending on the scene, dropping to slideshow speed in large boss battles.

After vid card upgrade in GW2:
Same settings, same framerate as before.
Ultra settings, same framerate.
Ultra with *super*sampling enabled, same framerate.
Ultra with *sub*sampling enabled, same framerate.
Vertical sync, same framerate.
Everything turned all the way down, no bells, no whistles, subsampling, etc: 30-50FPS.

What in the world is going on? This system, even with the mid-range CPU, should be playing this game like a bat outta hell. I get roughly the same framerate in the 3dMark11 tests as I get in the game.

The average framerate seems to be sitting right around 35FPS across the board.

Any thoughts?

Hey guys – We’re still collecting data in regards to this issue. While some players do have issues with their systems such as not meeting the minimum requirements or needing to update their video card drivers or even reseat their video cards, we recognize that some players with no issues are experiencing performance issues.

Please follow the steps below to provide us with some additional information in regards to the performance based issues:

1. Run Gw2.exe with –perfdebug as a command-line argument.

2. In the game go an area that exhibits poor performance.

3. Hit Ctrl+Shift+C to start performance profiling, this should take 15 seconds and post a message in the chat window.

4. Once it is complete it will dump a *.dat file into a “Profiles” folder located in the same directory as the local.dat file. This should also post a message in the chat window.

5. Attach the file to the thread, preferably zipped to cut down on size(4mb).
