Guild Wars 2

Hey all, not sure if this has been discussed here yet…Myself, as well as many other users, are experiencing very low GPU usage when is SLI (running most recent Nvidia beta drivers).

For instance, when I am out in the field exploring both of my 680s will run at 97-99% usage netting me 60-120fps depending whether I am in a big group or not (settings maxed).

Other times, like when in a big city, or even sometimes when I am out in the world, the usage will be around 40-50% dropping my fps to 30 and lower.

This doesn’t seem to be caused by any specific thing (such as extreme amounts of people) but almost seems random.

The gpu usage is more often than not under 50% per card.

I know a lot of people have posted this problem on other forums but it doesn’t seem as though there has been any kind of formal response or solution.

I think archetecture (buildings and etc) are “created” by the CPU and “painted” by the GPU. Hence at cities the frames drop alot and GPU usage accordingly (while at the same time CPU go at max).

hmm that makes sense. I wonder if setting max frames to render in the control panel would have any effect on this?

It’s called occlusion culling. Objects deemed to be non-visible/blocked by an object are not rendered, in a city objects are frequently in your field of view and objects behind are either not rendered or rendered at a low resolution. In an open field your view distance is much higher increasing the number of renderable assets and depending on your LOD Distance setting far away objects will be rendered at a higher resolution as they are not obscured by anything.

The FPS Drop would just be coincidental as in a city you’re relying more on cpu/memory performance than GPU as you are in a populated area, even more so in overflow.

there’s already a thread for this with 100+ replies… Anet has acknowleged the problem but there’s not any solution yet. Have you tried the beta drivers?

SLI nor Crossfire is officially supported in this game. Weather Nvidia or AMD adds their own SLI “fixes” to the game, there is only so much either of them can do considering the game itself does not support it.

People keep saying it’s a cpu issue, I am having the same framerate problem but my cpu is only using 30-50%. OP did you check how much your cpu is being used?
