This page belongs to games that nearly made the list, and all the games that were once on the list, but fell off due to better looking games taking their spots. These games are listed in no particular order.
Serious Sam 3: BFE
Very underrated in terms of graphics. It has the best parallax mapping ever, and the best implemented anti-aliasing ever (several levels of FXAA, up to 8x MSAA, and up to 4x or 8x SGSSAA, so it can actually look better than these screenshots which have no supersampling).
S.T.A.L.K.E.R. Call of Pripyat + Misery 2 Mod
Forced supersampling is a must, which means you’re limited to DX9 mode. DX11 offers improved view distance, dynamic wet surfaces (DX10 has this too), and slightly better lighting, but the aliasing makes it look worse. Pictured below is DX9 mode with 2x FSSGSSAA.
S.T.A.L.K.E.R. Lost Alpha
Once again, to get the best visuals you have to run DX9 mode with forced supersampling. DX10 mode has slightly better lighting, better parallax mapping, and dynamic wet surfaces, but the aliasing makes it look like crap anyway.
Keep in mind that it is overrated both in graphics fidelity and as a game in general.
This game’s overall polygon count, texture quality, and view distance are second to none. Compared to ArmA 2 and Day Z, ArmA 3 brings a superior lighting system, vastly superior shadows, even better texture quality, and higher polygon and resolution vegetation. It’s also much easier to run. It used to be on the list, at some point as high as #7.
Thief used to hold a position on the list, but has recently been shoved off by newer games.. Strong on graphics and weak on everything else, Thief is one of the better looking Unreal Engine 3 games.
The Elder Scrolls V: Skyrim
Another former entry on this list, but it has finally been retired. Mods are a requirement for it to be anywhere near this list. If you want the best looking and best playing Skyrim, use all of these mods, except for the Places and Quest mods, which make it potentially unstable.
Once you’ve got all mods up and running, the game looks very impressive. Great volumetric effects, amazing texture quality (average texture resolution is 2048 x 2048), some of the best vegetation, grass shadows, decent ambient occlusion, near-perfect anti-aliasing, amazing water, and the best object detail out there. You can go up to any object, and it will look incredible.
As of 2016 it finally got knocked off our list!
