I purchased a GUA2400BST Cyberpower desktop pre-built from Best Buy back in December. I get serious slowdown/stuttering on anything game in recent years, e.g. GTA V, Battlefield 1, Mass Effect Andromeda. Older games Like Dead Space 2 or Skyrim run fine. Even when I can get newer games running smoothly, there is odd pixelation of the graphics in certain places, like flames in Battlefield 1.
I have a VGA monitor running through an adapter into an HDMI accepting card, which as far as I can tell should not be an issue, but could be. Am I not using the profile settings for my games correctly? Did I mess up a driver installation?
