Ever since upgrading my GPU from a GTX 950 to an RX590, I've never been able to play D2 again due to sub-30 fps performance, regardless of settings. I've set the game to the high preset, low preset, and my own from when I had the previous card, and they all average out around 25fps. Nothing else in the system has changed, and the install location has stayed the same since I first got the game. I've tried reinstalling the game multiple times. I've had no problem playing other games at high FPS (such as Apex Legends at ~75fps with high settings). Below are my system specs: [quote]CPU: AMD Ryzen 5 1600 Six-Core Processor RAM: 32,703 Mb Video Card: Sapphire Nitro+ Radeon RX 590 VRAM: 8 GB Driver Version: 25.20.15021.1007 DirectX Driver Version: 25.20.15021.1007 OpenGL Version: 4.6 Number of Monitors: 3 Number of Logical Video Cards: 3 Primary Display Resolution: 1920 x 1080 @ 144hz Freesync Enabled [/quote] Any help or explanation as to why this is happening would be great. [b]EDIT:[/b] I've found the issue. In my computer I have a GTX 550 Ti that I use only for driving extra displays (so I don't use any extra Vram on my main GPU, the RX 590). For some reason Destiny 2 doesn't like this and drops to half the frames it should be at (I could confirm this after disabling the 550 Ti). It's a shame I have to choose between a game I like and productivity, so I guess I'll just be playing other games that are fine with this odd, but useful, configuration.
