I'm not overclocking my rig. It's a standard default hardware setup. I tried using the Wagnard Tools TDL manipulator..also tried changing it manually to increase the value. No luck either way. Double checked the nvidia settings were dedicating the graphics card to the game, not some cpu default... turned off a lot of the fancier settings... tweaked the power settings a couple times for performance/quality but even that was supposed to only be a deal for laptops. Double-re-checked-installed my drivers... i dunno. Even tried running the included unreal prerequisites package that the game includes as an extra. The game seems to run smoothly for me with no stutter or graphical issues and then BOOM, D3D device lost about the same couple minutes in, whether i'm in combat or not just walking around. It's depressing.Decrease ur gpu over clock
