8 months ago Do you potentially mean 16x anisotropic filtering and not 16X MSAA?
Anisotropic filtering improves the quality of textures when viewed at an angle and does typically have a negligible performance hit.
MSAA on the other hand is like a selective super-sampling to render specific elements of a game a higher resolution to reduce aliasing and while it isn't as demanding as just selecting a higher resolution, it does have a noteworthy FPS impact.
For example, on my 6950 XT with GTA V going from MSAA off to 8x MSAA takes me down from ~150 FPS to ~80 FPS. If you're actually talking about MSAA here, then the FPS drop you are seeing is 100% to be expected

Description and steps to reproduce [Required]
Without MSAA, Max settings, in the American map, I'm getting 120FPS, and with 16X MSAA, I'm getting 55FPS. Sure, MSAA has a cost, and 16X even more, but this shouldn't drop performance this much. This goes along to what I noticed about Arc struggling with MSAA in basically every game, leading sometimes to crashes, and sometimes to very low performance. I couldn't find online a 16X vs. no MSAA for other GPUs on Dirt Rally 2.0, but on most games, there's at most a 10% difference. Here, it's more than 50%
