Guild Wars 2

The details of this topic are far too unclear to find a potential cause and will likely receive no attention from mods and/or technical support personnel. Are you talking about a drop in FPS, or are you experiencing network latency (some users will notice this as a delay in skill usage, ‘bouncing’ characters, etc)?

If you are in fact experiencing increased network latency, I recommend running a tracert to determine where the latency is coming from. On Windows OS, follow these steps:

1. Click the ‘Start’ button on the bottom-left corner of your screen
2. Navigate to ‘All Programs’, then ‘Accessories’
3. Open up the ‘Command Prompt’
4. Run the following command: ‘tracert www.guildwars2.com’

This will give you a list of the nodes (points of connections such as your gateway, WAN, ISP, etc) that your connection goes through. Usually, you will experience anywhere between 8 and 15 returned nodes (called hops). To determine if the latency you’re experiencing is in fact server-side, you should be able to see a clear separation between geo-physical locations such as one hop representing your city (it should be in the address name) followed shortly thereafter by a different city.

If the largest returned response times are between the first hop and your city’s hop, the lag is likely due to your ISP or gateway (router/model); vice-versa, if the largest response times are outer-city hops then it is much more likely to be server-side.

If network latency is not the issue, and you’re talking more about a drop in system performance, this is a natural occurrence and ArenaNet can do very little to offer support. In those cases, reducing visual display settings is an easy solution (more specifically: Particle effects, Bloom effects, and Anti-Aliasing). Depending on your system and monitor, enabling Verticle Sync may also provide some improvements.
