Hi,

Recently I’ve noticed my crossfire for triple monitor setup stopped working properly. This happened probably in the last 2 months or so. Before that it was working fine.

I run a 3 monitor display setup with 2 27" (2560 × 1440) monitors on 2 sides and a 34" monitor (3440 × 1440) in the center. The total resolution after benzel adjustments is 8984 × 1440.
It used to run my gw2 client at around 50 to 60 frames per second when using crossfire mode with 2 AMD R9 290 cards. But now it only runs it at 7 frames per second. The processor that I’m using is a intel I7-4930k with 64 GB of RAM installed. The same resolution runs at 30-40 frames per second if I only use a single AMD R9 290 graphics card.

Obviously I would like crossfire working again so I can run the game at 50 to 60 frames per second again.

Anyone else have problems with triple monitor displays?

Edit: I should also note this is the case for both 32bit and 64bit clients. And that I use windows 8.1 . I’ve also tried the AMD drivers from June 2015, same thing happens. So I feel it has to do with gw2 than it has to do with my gfx card drivers.

Edit2: Also forgot to mention the crossfire mode at this resolution works fine with other games like Hitman Absolution.

So can Anet support team please notify the development team to take a look please?

Most of the games profile are in the driver but sometime it stop to work.
Have you tried to make a custom profile for the Gw2 Client and force Crossfire ?

yes.

its low frame rate because crossfire is enabled actually. it goes down to 7 frames per second. if I run it without crossfire it gives 30 – 40 frames per second running on a single card.

I then try other games like hitman absolution crossfire works just fine.
I also tried forcing gw2 to run 32 bit version vs 64 bit version via commandline. both the same.

Thanks Anet for fixing this so quickly with the new build that came out a few hours ago. Now when in crossfire mode for my 3 monitor setup the frames per second doesn’t drop to 7 anymore and is performing better than a single graphics card. An improvement from 30 to 40 fps vs 40 to 50fps Although I feel crossfire mode could do better still than it currently is as I’ve noticed both graphics cards aren’t being fully utilized. I’m not sure if this is a drive issue or if its a gw2 client thing. But I do remember 1 year ago my gw2 used to fully utilize both graphics cards (as in they are 100% busy ).

On a side note, for triple monitor setup the Glider bar seem to be located on the right monitor instead of the center monitor. I will make another thread in the bug section so it is easier for u to treack.
