About new graphics of AOE 3 DE

The blurry graphics are the result of the anti-aliasing the game uses. TAA is the worst, although they did improve it somewhat in the last update, and FXAA is slightly better, but still blurs the graphics too much to my liking. You can solve the blurriness problem by either turning off the anti-aliasing in the graphical settings menu or by applying sharpening through your GPU software, as detailed here. My personal preference is to keep TAA on and to then add sharpening. I find this strikes a good balance between eliminating aliasing and making the units distinguishable. You can check out this thread for some screenshots. Just note that those were taken before the last update in which the TAA was somewhat improved.
