Before I get started on my problem, I am trying to get help with Fortnite mostly. All other games work fine. I am not sure what the problem is. I have tried changing multiple settings in Nvidia Control Panel and in windows it self for performance. Nothing has helped. All my game settings are low. I have reinstalled the game completely, I have reinstalled all Nvidia/GPU related drivers and softwares. Nothing has helped. I just recently got my GPU by the way (I was having the problem with my old GPU, GTX 950, so I figured why not upgrade) I upgraded thinking it would help. The problem still persists. I also have no idea if this is a bottleneck problem. I have tried overclocking my GPU. I am getting very frustrated over this problem, the game is unplayable for me. I would honestly appreciate it more than you would imagine if anyone could help me find a fix. PLEASE I'M DESPERATE! (Also thanks for your time and help in advance). Any info anyone needs, let me know I will provide. And again thank you.
