I've noticed that enabling Fidelity FX Sharpening causes awful aliasing. I'm running the game with the Res scaling set to 75 percent on my 1440p monitor. So the game renders at 1080p.
If I turn on Fidelity FX sharpening at either 50 or 100 percent it produces awful aliasing. You can tell the texture sharpening part is working (since I'm pretty sure this is AMD's Contrast Apatite Sharpening). But for some reason it causes the awful aliasing. I've attached screenshots to demonstrate. It's most noticeable on the boards in the flashlight and the chars jacket collar.
I've tried using sharpening with TXAA, FXAA, and no AA. Makes no difference.
Edit: Seems I can't post links
