Crashes, especially in pvp?
There’s no reason for you to crash using a 970. Check your nvidia drivers are up to date, and it might be worse making sure that your graphics card is securely in the pci-e slot, and screwed in place. A GPU that’s not properly inserted can cause all sorts of issues. If it’s especially prominent in PvP then I’d imagine the extra particle effects could be causing issues due to the card not being inserted properly or potentially being faulty.
There’s absolutely no reason that a 970 should be having any sort of issue with GW2 unless there’s something wrong somewhere.
Thanks for the useful advice, it didn’t help.
For anyone having similar problems, I’ve found that decreasing the resolution from you native spec seems to practically remove crashes in general, so in the future for anyone having problems like this just decrease your native resolution.
