encountered an unrecoverable driver error
Update: Have the newest drivers 310.54 still happening. ANET we need answer more than what you have posted in the suppurt FAQ. That does not fix the problem.
So I have had this problem for a long time. I believe I have solved it for myself; however the fix is not a fix I like, yet it works. So what I did last night was downloaded MSI Afterburner. After that I down clocked the core 100mhz. I I played for 5hours straight in WvW(where I mostly black screen) and not a single crash. I then tried only a 10% down clock. For that was only 58mhz taken from 583mhz. I played for another 4 hours straight all in WvW with huge serfs from all 3 sides and no crash. I am glad that I can play now worry free, but this is not how it should be fixed. Anet still needs to look into this and find a 100% fix with making dumb changes to nvidia options or having to down clock the GPU.
I’m leaning towards the fact your GPU can’t handle the load requested by the game. Its a hardware stability issue and can degrade overtime.

This could be true; however, I play games such as Battle Field 3 with maxed out settings and do not get any issues. The crazy thing is during Beta testing I had no problems what so ever, yet when the game came out 8/2012 The problem started to happen.
I had this problem before and have solved it by entering my GPU Control Center > Gaming > 3D and adding Gw2.exe to the list then playing around the settings. I hope this solves the issue for others because I remember going through hell, and know that till now, this issue still occurs for many.
