Hi all,


I've had this pc for a while now, and it's never really performed the way you'd expect it to, but its always been good enough to do what I wanted it to do with some slight nerfing.

Lately though, it has gotten noticably worse.  It lags on Skyrim, lags on Witcher 3, lags on Black Desert Online, etc.


I'm talking poor fps, snaggy game play, etc.  Granted this isn't a brand new machine/card, but it should be able to max these things no problem and doesn't (and never has).

I've tried various settings, updated drivers, and in the end had to nerf the graphics on things, which I shouldn't have to do.

I maintain it regularly:  Its clean, its updated, disk is defragged, all that good stuff.

I don't really speak the language DXDiag does, so I'm wondering does anybody see anything in this read out that would explain my poor performance on games?


I'm on the verge of trying a new card, and am trying to find other answers first.
