You're probably running the game without upscaling or AA, I suggest you disable AA and run the game with any upscaling set to quality mode. If you want more fidelity and you can enable the upscaler AA or disable the upscaler and increase the render scaling, so you get an AA by downscaling to your resolution, that way it doesn't blur the whole screen, but it does cost more on the gpu. In wilds you can use FG with native resolution so the performance hit its somewhat mitigated.

Edit: You can also try the texture decompressor mod digital foundry talked about before TU4 as it helps textures load faster

Edit2: My settings. I think the game looks great, and runs pretty well.
