There are tons of PC games these days but some of them will demand large processing power PCs. Although at the moment, there is Large Pixel Collider and Maximum PC's Dream Machine that represents the best gaming hardware available, the price at stake is $10,000.
PC Gamer collected some demanding PC games to play these days. They have also tested each of these games running at 2560 x 1440 and maximum quality on a GTX 1080 paired with a 4.2GHz i7-6800K.
One of the first DirectX 10 games to hit the market, Crysis, was released in 2007 and pioneered the use of several advanced rendering techniques. It continues to demand high-end settings and until now, it still runs poorly even on its highest settings.
Hitman (2016) demands a good CPU with multiple cores if possible and it should run in DX12 mode to fully utilize the CPU cores. Lowering down the settings can offer a big boost to its performance and maintaining 60 fps at 1080p 'ultra' is GTX 980/1060 6GB or RX 470, while at 1440p the GTX 1080 offers good running.
Grand Theft Auto V (2015) can scale way back on image quality and get much higher frame rates. However, if the settings are maxed out, it will hurt the GPU.
Battlefield 1 (2016) can perform well on a large form of graphics cards. Single-player campaign works fine, but multi-player will beat the CPU.
Ubisoft's Far Cry Primal (2016) uses a different engine and skips few of the Nvidia-specific technologies. Although it doesn't run well on every card, the HD texture pack installed, the GTX 1080 manages to maintain a constant 60+ fps.
The Division (2016) sports reflections, dynamic lighting, parallax mapping and contact shadows alongside some of the Nvidia GameWorks technologies like HBAO+ and HFTS (Hybrid Frustum Traced Shadows). To enable certain features like HFTS, an Nvidia GPU is needed.
Other games that demand high-end settings on PC are The Witcher 3 (2015), Ark Survival Evolved (2015 Early Access), Rise of the Tomb Raider (2015), Ashes of the Singularity (2016), Arma 3 (2013) and Deus Ex: Mankind Divided (2016).
