Guild Wars 2

Ditto on Aniso; performance hit is negligible but the results are not.

AA Gamma won’t do anything since its only for OpenGL.

AA Transparency can make for a significant performance hit (if it does anything—seems to depend on how textures are made but that’s just a guess) and, in some cases, gives PowerPoint FPS (check foggy areas with wrought-iron fences).

Spontaneous reboots (NOT BSODs w/auto-reboot) are 99.9% the power supply failing to deliver proper power under load.

The reason GW2 is doing this and not other games is because GW2 is more demanding (more stuff for your CPU, GPU, RAM, Chipset to do) and stresses the PSU more.

My BIOS is set to not reboot on power failure and yet the box was rebooting, so its not a PSU failure (I am using Corsair AX750, which is more than enough).

In my case, rolling back to an older Nvidia driver fixed the problems (I am using the same 670 Windforce as the other poster).

Way off base here. The option to which I refer is Control Panel | Advanced system settings | Startup and recovery | Automatically reboot on error (uncheck this option). Your BIOS setting doesn’t verify your PSU’s health but I agree your Corsair 750W is enough (check the load on each rail though).

Barring hardware faults, the common theme seems to be a brand new video card (600 series) with a brand new game and both are having issues. Pinpointing software faults will require technical details and steps to reproduce the problem (not “all my other games work, GW2 doesn’t, I have ‘the latest’ drivers, please fix”), to include driver and various in-game settings.

I can see a 150W laptop PSU choking on GW2 (or any other demanding game); tolerances are tight as it is without attesting for build quality.

I’ve only had one lockup and that’s because I was testing GPU, VRAM overclocks on my 580, which brings me to another point: I haven’t found a video benchmark sufficient enough to stress test the video card (not even Uniengine Heaven). The only testbed I’ve found are games (currently Metro 2033 and GW2 with Prime95 and Intel Burn Test running in the background to test the entire system, not just the GPU on an idle system).

Are you installing, running with an administrator account?
Is UAC enabled/disabled?

If you have to turn off your computer to let it cool, something is wrong: clean it (to include components) and ensure fans are properly installed and working.

Underclocking is a great way to test and a potential workaround. If overclocking averts lockups/crashes, either:

- Components are breaking down and no longer perform at spec (GPU, CPU, Chipset, PSU)
- Cooling issues (really takes effort to keep video cards clean)
- Inadequate power (Antec 650 should be fine but I wouldn’t have confidence in it as much as an Enermax)

For the PSU, you have to check the current draw of the video card and compare it against the PSU’s current capacity for those PCIe connectors plus whatever else is on that rail. The label on the side of the PSU will have that information. If you have peripherals on the same rail, move them to a different one.

Sidebar: To fully eliminate software issues, build a fresh install (another disk or partition) and only install Windows & drivers, DirectX, GW2.

Spontaneous reboots (NOT BSODs w/auto-reboot) are 99.9% the power supply failing to deliver proper power under load.

The reason GW2 is doing this and not other games is because GW2 is more demanding (more stuff for your CPU, GPU, RAM, Chipset to do) and stresses the PSU more.

If you can, make a copy of your GW2 directory and then copy it back onto the new machine. Next, run the GW2 setup and it will install and not have to download anything. This works for GW1 also.

I neglected to mention power supplies: make sure you have a proven, quality brand PSU that exceeds requirements (600W minimum) and blow all the dust out of it and ensure your fans are working.

All PSUs are NOT the same.

- Correlation is not causation; memory failing has little to do with GW2

- GW2 puts a far greater demand on the video card than D3; my 580 yawns at D3 but GW2 can peg it at 100% utilisation regularly

- Joeltron: it is difficult to provide technical info when we don’t know which video card you are running

- Driver 306.02 and the beta before it ran fine on my and my wife’s machines, GTX580 833/2066

- I use MSI Afterburner (doesn’t require MSI hardware) to change clocks and monitor FPS, GPU util

- Run memtest 86+ overnight, run VMT (video memory test) as well as full video diags; ensure hardware (heatsinks, fans) is thoroughly clean, especially the video card’s boxed-in heatsink

- Ensure case has plenty of airflow; test with cover(s) off with a desk/floor fan blowing in it to eliminate airflow issues

- Run chkdsk /r, sfc /scannow, reinstall DirectX, run Windows update, clean install video drivers to check for software issues

It sounds like the driver is restarting. Check temperatures/airflow and if you’re overclocking,
set clocks to default for troubleshooting.

Check your drivers again; Diag shows you’re using old one.
