Did you disable vsync? That makes it way more obvious when the cap resets. You also need to make sure your cap isn't too high, because then you'll have the GPU maxed out, which will make the CPU frame times inconsistent. Basically, you always want your GPU graph below your CPU graph (except with dual GPU's).
I'm on Windows 10.
Yeah, Vsync diabled and cap set to my refresh rate, no issues at all. You're using a CrossFire configuration, did you try disabling it to see if the issue persist?
Actually, I misspoke, you have to click "options" for it to reset. But it will immediately reset the cap, you don't have to mess with any video settings. I actually fist noticed it when I went in to only adjust my mouse sensitivity.
But yeah, it happens with crossfire off too.
Yeah, now I can see the option. The CPU line starts to get a bit "crazy" but I don't get inconsistent frame rates or sttutering.
Maybe it's a bug / engine limitation. Also, keep in mind that GW2 does not include free access to the console like other Frostbite 3 (BF3, BF4, Mirror's Edge Catalyst, NFS...) so maybe some config commands are not fully supported/test. This looks like a bug to me.
Yeah, that's why I submitted it to "bugs and issues". I'm hoping a PopCap dev will see it and fix it in next patch, and hopefully it's not a complex fix.
But yeah, I usually play with vsync enabled, and when you don't have your frame rate capped to your refresh rate, it throws off the game's internal frame pacing slightly and causes minor judder with mouse movment. With the cap enabled, mouse movement is very smooth. Capping fps to this value will also reduce input lag slightly, I learned that with Battlefield 4.
But if you're a person that plays with vsync off all the time and no fps cap, you wouldn't really notice this sort of thing anyway because you're always seeing some degree of stuttering.
