Guild Wars 2

Check the GPU usage of all GPU when the game is running. There is a chance the game is using the Intel GPU. If it is, you will have to disable the Intel GPU from bios.

You might be having the same issue I was having if ur GPU is getting low usage. Next time you run the game check the GPU usage of all the GPUs. If your Intel GPU is getting 100% usage, then the game has picked ur Intel GPU over ur GTX 680.

I have a GTX 670 with i7-3770k running at 4.0Ghz. Performance wise, 3770k is maybe slightly higher than 2600k. I have the game running at 1920×1080 fullscreen windowed with all settings at max and I get 53fps with the same shot. So you should be getting around same or better with a GTX680. My GTX670 also runs around 70-90% usage. It was like at 20% when the Intel GPU was being used.

If your game is using the Intel GPU, then you will need to disable it from bios to force the game to use the GTX 680.

Try checking how much GPU usage you are getting when the game is running. If your video card gtx 670m isn’t getting like 100% usage, then check the usage on ur intel gpu. You may be having the same issue as me, where the game picked ur Intel gpu instead of the gtx 670m. If this is the case, you will need to disable your intel gpu from the bios to force it to use the gtx 670m. Keep in mind that disabling it on ur laptop will hurt ur battery life when ur not gaming, since it the gtx 670m uses more power than the intel gpu.

Yes disabling the HD4000 from bios will stop this, but I shouldn’t have to do this. This issue only happens to GW2, every other game gets the GTX 670 as the gpu. My monitors have always been plugged into the GTX 670. And no it is not in power save mode. It is a desktop, I never switch power options on it.
If this is happening to me, then it will probably happen to someone else. Not everyone is going to figure out GW2 is using the wrong gpu. I saw a few posts talking about low fps, but with different hardware, on the forum. It might be the same issue.

An option to select graphics card needs to be added. My game has been running on max settings since launch, but today it dropped to a crawl at 7fps. My GPU usage was at a whopping 7% usage. After checking different meters, GW2 for some odd reason has picked the integrated HD4000 over my GTX 670. I use my laptop every now and then, which has an ATI card in it. So I assume that was why my graphics options reset, but I don’t understand why the game picks the HD4000 over GTX 670. Please fix this or tell me how to get GW2 to use my GTX 670 again instead of the HD4000.
