Guild Wars 2

hi everyone
please help me out please i have
windows 10
intel 4790k 4ghz cpu
16 gig DDR3 RAM
corsair 850 psu
gigabyte 980 ti gpu

and when i start the game on 4k with all settings set to high only and no reflection i get 18 fps average in the starting are for human lvl 1.
and the crazy thing is i just came back to the game with 2 other friends we created a char and wanted to play they get average 60 fps and i get 18-20 they have the exact same system we built our system same time and that’s what drove me crazy
i followed the steps for GW2 forum to fix low fps but nothing changed same result
i even clean uninstalled nvidia driver and installed the new one 355.82 for windows 10 and uninstalled the game and reinstalled it same result !!!!

please help me out.

Are you running precision x? I was messing around with it this week, and found elsewhere on the forums that it was causing issues for another. I was only using it for a fan curve to start out, but found that after I uninstalled it my game ran much smoother again.

i don’t know what is precision x so i assume the answer is no
but i just found out something even crazier
i went to fire camp me and my friend on Skype with same system(GPU, CPU, MB) he has 60 fps i had 18 so for the fun of it i changed my resolution to 1920×1080 p and guess what i still have the same fps 18 !!!!

sounds like typical PCIE link issues here.

Download GPU-Z and while GW2 is running in a window verify that your 980Ti is linked at 16x for a single PCIE card or 8x if you have 2-3 PCIE cards in that system.

4790K has a total of 16x lanes.

that’s what i got is this mean my gpu is running at 2x ?

that is correct, and thats the issue.

first make sure the GPU is in the PCIE x16 slot CLOSEST to your CPU.
Pull out the GPU, blow out the Slots with a can of air and blow out the PCIE connection on the GPU and reinstall it.

Boot and reload GPU-Z to make sure its linked at 16x

i did this and i still have the same issue still running at x2 what should i do next ?

thank you so much for your help i fixed the issue
weird solutions but it worked. i have ASUS maximums VII formula and the hards sata cables sit below the vga so i just took them of from the top slot and used only the bottom slot which wont touch with the vga and some how this fixed the issue im thinking it was interfering with it and not making a perfect connection.
one more thing my friend GPU-Z says
PCI-E 3.0×16 mine still saying PCI-E 2.0×16 and we have the same MB why is that ?

Inside your BIOS there should be a setting for this. You can manually change it to perhaps ‘auto, pcie 2.0, and pcie 3.0’
