Why is it necessary for him to post his specs? It makes zero difference if he is running a beef rig or a shitty one, as long as he states that the game usually runs at a better rate then it currently does on a substantial level.
His problem can only be caused by a handful of things, none of which can be narrowed down by knowing the name of his graphics card or CPU.
Chances are that something he opened was eating away at his CPU or GPU and he either didn’t know it was eating it and kept it up, or it was doing so invisibly in the BG. Hell, maybe there was just a memory leak or something.
Either way, his specs wouldn’t have helped AT ALL.
If anything you should refrain from posting your specs, because everybody always just assumes your PC should be upgraded to hell and back even if it has nothing to do with the current troubleshooting.
