My FPS is usually a healthy 160-200. Every like 3-5 minutes, my FPS will drop down to ~30 FPS as if I were sent into a cutscene. In areas of heavy fire or with a lot of enemies, it will drop to frames as low -blam!-. It stays this low for a solid 30s - 1 min, and will instantly shoot back up to my usual FPS, causing some momentary screen freeze. I can't say it's a hardware issue since Destiny 2 is the only FPS game that behaves this way, everything else runs perfectly. I'm unsure how to fix this or if this can be fixed since I can't find any surefire solution yet.
