Basically what happens is when I force one GPU ,specifically B, to run dedicated Physx, then I can boot up the game and play it no problem. Though if I choose auto select, CPU, or (A), then my monitor will crash at a certain point and I'll have to do a hard reset. Also this is all under the condition that I have V-sync turned on, otherwise no matter what GPU or CPU uses my monitor will crash.
Anyway, what I'm looking to find is a way that I can enable multi-gpu, otherwise I have to dedicate one of them, gimping my comptuer's performance. If any additional information is required just tell me how I can provide it and I will. Also, this happens in multiple games, not just GW2.
Edit: Some screenies of GPU-Z with GW2 running in the background (login screen). Also this is with one gpu dedicated to physx.
Edit: I'm not sure but I think I found out what was causing the crash. After allowing both my GPU's to run and looking at the "Graphics card" tab in GPU-Z I saw Cuda and Physx were not able to run on this setup. So I disabled the settings in my nvidia control panel to use both GPUs for CUDA, also disabling Physx, and so far after opening Tribes Ascend, a game that would normally cause me to crash after running multi-gpu, I haven't crashed yet.
Edit2: Ok, turns out it still crashed lol, but at least it was later then usual and not at the login screen. Gw2 also works fine at the login screen. I have some logs from GPU-Z that I dont want to post becuase they are too long and I dont know how to mark things as spoilers. Though the things that stand out the most to me in there are that my GPU load is always 0%, aswell as my fan speed. Also my GPU clock speed spiked 2 seconds before the crash, then plummeted. Also:
I'm really starting to feel like that dog.
