As long as the DLLs are loaded (check in processes and services in Task Man.), EVGA Precision and MSI Afterburner can cause c0..5 (access violation) errors, as can overlay programs (raptr, Steam, Mumble, maybe Xfire etc too).

I would – in general – take ping, pathping and trace route results with a grain, nay, two of salt. Not getting replies to ping packets is normal, and in itself doesn’t mean there definitely is a problem, only that we can’t tell if there is a problem. Routers can be – and frequently are – configured to not reply to ICMP echo (read: ping) request at all, or assign a low priority in favour of actual data traffic.

If not for anything else but an alternative viewpoint, try a trace route with TCP instead:
- Install tracetcp (http://sourceforge.net/projects/tracetcp/files/)
- Install WinPcap (http://www.winpcap.org/install/default.htm)
- Open the tracetcp folder, click the right mouse button while holding down ctrl+shift, open a command prompt from the context menu
- run tracetcp 206.127.158.1 -n -p 5

You can also test port connectivity with target:port (e.g. 206.127.158.1:1337). Append ‘> file’ (e.g. tracetcp 206.127.158.1 -n -p 5 > tracetcp.txt) if you want to save the results into a file.

Here, consistenly high latency and high packet loss (say, > 5%) are things to look for.

Well, “Fatal Error: Fatal disk-error (6) on write” indicates a hard drive access related issue, so:
- Make sure you have enough free space.
- If GW2 isn’t installed in Program Files, make sure none of the files and folders are read or write protected.
- If GW2 is installed in Program Files, run the launcher as admin.
- Run -repair once.
- Consider running ‘chkdsk /f c:’ from command line (will probably require a restart), replace ‘c:’ as appropriate, if GW2 isn’t installed on the C-drive.

- You could try the ‘/clientport 80’ option: https://forum-en.gw2archive.eu/forum/support/tech/10-5-11-2130-101-closed-connections/77719
- Run as admin if it doesn’t ask you to elevate
- Put your computer into your router’s DMZ (but enable Winderps Firewall before doing so)
- And the DNS cache flush: https://forum-en.gw2archive.eu/forum/support/tech/Launcher-all-of-a-sudden-won-t-connect-to-internet-or-even-re-install-the-game/34995

e: DNS.

Out of Memory errors are likely to be memory leaks or buffer overruns, and require a code fix.

According to the internets, icf.dll is a McAfee file (firewall perhaps). If you do have McFailee installed, find an option that allows you to add programs to its firewall’s ‘allowed programs’ list, and run the launcher as admin (although that shouldn’t be necessary). If gw2.exe is already in the list, remove it and add it again, giving it full interweb access.

- Get SpeedFan. Monitor CPU/GPU temperatures and CPU frequency.
- Get GPU-Z, open the graph window and monitor GPU frequency.
- If neither the C/GPU clock down, it’s not overheating.

If it’s not overheating:
- Get Process Explorer, run it and double-click gw2.exe. Ignore the symbols notice, and open the tab which shows CPU usage per thread.
- Open task manager, select processes and arrange by CPU usage.
- Are all of your CPU cores and GPU very highly utilised during the slowdown?
- Do the CPU/core usage %ages in SpeedFan, task man and proc explorer match?

I have a P8400 C2D @ 2.26 GHz and a 9600M GT (yes, laptop), close to minimum specs. Normally I have 90-100% CPU and GPU utilisation. There are some instances where the first core drops to ~30% util for 30-60 seconds, and some specific DEs seem to be hurting too. Other than that I’ve reached as high as 70 FPS. I’m confident that with reasonable graphics settings, some optimisation and bug fixes a better desktop should achieve more playable performance.

Confirm that your GPU is really operating at maximum frequency, and your PCI-E link is actually at 16×.

Limiting FPS reduces workload, if this fixes it, likely cause is overheating. Get SpeedFan and observe temperatures, you could also run a memory test. Visually and aurally observe that all fans are working.

I get some severe FPS drops, so I’ve attached a dxdiag, but there is more to this issue.

Now, the explanation. I normally get low-ish, but tolerable FPS. However, every now and then I experience a severe drop in FPS for I would say approximately 30-60 seconds. The FPS then goes back to normal instantly. This usually happens a couple of times, separated by 10-15 minutes or so, and reduces in frequency the longer the GW2 has been open.

I have excluded overheating as a cause for the following reasons:
- CPU and GPU keep operating at maximum frequency and do not throttle down.
- GPU temperature is acceptable according to measuring software.
- CPU temperature is acceptable due to point one (cannot be measured, sensor has never worked).
- From past experience with overheating, FPS does not instantly return, it takes several minutes to recover after throttling to single-digit FPS.

During normal gameplay, both cores (dual-core C2D) and the GPU are fully utilised nearly 100% all of the time. What is consistent with every single slow-down is the following: core 0 becomes under-utilised, while core 1 remains fully utilised (see: image). In other words, a sudden drop in the usage of one core causes somewhat periodic slow-downs.

For some reason the task manager’s taskbar icon shows (see: image) 100% utilisation, whereas looking at the task list clearly this is not the case. Furthermore, task manager shows 70% utilisation gw2.exe, but the percentages shown by Process Explorer for gw2.exe are not even close. It almost feels as if a thread is stuck waiting for something. Tying up the CPU but not actually doing anything with it.
