Game says X fps, is actually running at Y fps

[solemn.9670]

i.e. it will say 40 frames per second but actually it's stuttering and dropping frames so much in some areas that even though it says 40 FPS consistently, even when I move my mouse around, visually it appears to be about half of what it says - 20 frames if it says 40 fps. This only occurs in some areas and at certain times. I can't tell if it's my PC or just the game.

install FRAP and see if it shows the same numbers as the in-game FPS counter; I see it to be pretty accurate on mine, so I dont bother turning FRAP on

Ya, I could do that for a more accurate measurement, but the difference is pretty clear between what 40-50 fps looks like and what I'm actually seeing which is extremely inconsistent. My eyes know low frames when they see it

I've never encountered any inconsistency between GW2's reported FPS via the Options window and other overlays that report FPS, but I also never encounter much 'stuttering' or 'hitching.'

 

i5-3570K @ 4.5 GHz (on Z77 platform). 16 GB (2x 8 GB) DDR3-2400 @ CL10.

GTX 1070 @ 2050 MHz (EVGA FTW). GW2 installed to a SATA III SSD.

 

I typically see around 100 FPS in newer maps and up to VSYNC limit of 144 FPS unless there's a large number of player characters or NPC models around.

Higher performance settings I stick with are Character Model Limit: Lowest, Shadows: Low, and Reflections: None.
