Guild Wars 2 running like crap on my GTX 1060. + other games.

In the Nvidia Control Panel, under "Manage 3D Settings" --> "Program Settings" select the games you are having an issue with (or add them if they are not in the drop down list) and then change the "Power Management Mode" to "Prefer Maximum Performance".

Try that at first.

Not reading the comments but is the video card new or used? I had a similar issue while playing the elder scrolls online recently. My in game experience was sluggish, the graphics were running slow and had tons of frame skip/low frame rate. I have a 3 year old video card. The gpu was overheating, i had to take it apart and reapply thermal. The problem was resolved, i was back at running at a high frame rate.

It's your CPU. Get Intel.

your problem = mix nvidia whit amd. never do that...... or nvidia + intel or amd whit amd.

my choice nvidia + intel always i do that and i never regret it.

i buyed 2 times amd PC and both times i regret it. they are fucking slow and the pieces break really fast and you need to buy another ones....

i will never more buy AMD things

amd lol

is Game DVR from xbox live is on?
if on, try turn it off

did you check cpu/gpu usage? just monitor those values with certain tools, and if you see ~100% usage when the stutters happen, you know which component is bottlenecking.

Low frequency of RAM, i think better to change it on RAM with higher frequency (And also bad timings of RAM)
Your CPU and Motherboard support's freq. up to 1866 MHZ And if you would like to buy RAM, better change 16Gb one module on two module by 8Gb, it works faster so.
So i think you better change memory on mem with higher frequency.

Best wishes.

What are your GFX settings in GW2?

lol that gpu and then amd cpu...... also games ALWAYS stutter if you only play on 60hz...

I have now... over 8,000 hours in GW2.
And I've played GW2 on several systems in this time and can tell you
CPU > all and -> SINGLE core performance > All
For example GW2 runs totally fine on 7 years old Core2Duo E6300 ;) even with a Videocard form 2005
But doesnt work very well with an FX-8320 and a 280X
And no it has nothing to do with AMD or Intel
The newer AMD CPUs have nearly all 6/+ Cores (nothing for GW2 its not multi CPU optimized like nearly all mmorpgs :/ )
GW2 runs perfectly on an AMD Phenom II x4 955BE, for example
Guild Wars 2 needs nearly 0 GPU Power to run "okay"
I have in the 4 years GW2 which I play.. switchted from a 9800GT to a HD6850
then R9 280X and now to a GTX 1060. The performance improvement is minimal.
I know many in the game with an FX CPU... who have problems with it and others have none
.... but you just need to google "AMD FX GW2 FPS" or something similar
and your question where the problem is answered by itself

Current System i5-4460+GTX 1060+16GB ... runs absolutely perfect

Recently upgraded to a 1070 - No issues. Experience: GW2 from day 1, all builds on Nvidia cards.

Current build (all clocks are factory):
Core i7-4790K 4GHz
8x4GB DDR3 1600
GIGABYTE GeForce GTX 1070
WD "Blue" 1TB HDD
1KW PSU
Win 7 Pro x64

GW2 Settings:
All max, all enabled

Honestly, I'd memtest. There's always the possibility you have a bad module, but it's not so far gone that it's blue screening. Happened to a friend recently - everything ran, some things great, but on test a stick was just bad. It happens.
