With huge advances in technology, massive improvements in hardware and software have created intense 3D gaming experiences with systems able to do more than ever before. The major source of power comes from a central processing unit (CPU) and a graphics processing unit (GPU) which have very different roles. Listed here are some of the most GPU graphically demanding PC games of 2021.


A GPU is a processor made up of many smaller and more specialized cores that work together to deliver huge performance since a processing task can be divided up and processed across many cores. The CPU is often referred to as the brain of the computer that executes the commands and processes for the computer to run and determines the speed it can run. 

GPU technology has already been introduced into online casino gaming. The popular 888casino has adopted the same high-quality motion graphics as seen in consumer-based gaming devices including embedded GPUs to enable stunning, immersive visual experiences. For this reason, it is not surprising that the site boasts an impressive 25 million registered users.

GPU intensive games

GPU intensive games are those that process 2D and 3D graphics, incorporate details in textures as well as mapping texture. The most obvious example is Call of Duty: Warzone. In contrast, a CPU intensive game involves several dynamic objects that could include shadows, terrain, textures and more such as found in Assassin’s Creed: Origins and Total War: Warhammer 2.

Graphics help to promote the storyline to be successful.  A clear example of the importance of graphics is in Grand Theft Auto V, launched in 2013 and number two in the bestselling game after Minecraft. 

Cyberpunk 2077

Launched in December 2020 after several postponements, this game from CD Projekt sees players taken on the role of V, a mercenary living in the dystopian world of Night City. The game currently only plays well on PC and a 2070 Super or similar GPU, 1080p or 1440p with ray tracing should work well. The PS4 and Xbox versions are under review.

Microsoft Flight Simulator 2020

This next-generation flight simulator for amateurs has been revolutionary in the industry. Players can fly anything from light planes to wide-body jets. Using data from real-world satellites the game has arguably the most precise graphics of any video game. This game demands the higher-end GPU cards currently available.

Dirt 5

This off-road car racing game from Codemasters runs best on a six-core CPU and a fairly high-end GPU, yet its minimum specs are far easier than the other games listed. The game features not only dynamic weather but also maps from North and South America, Asia, Africa and Europe. 

Grand Theft Auto V

Launched in 2013, Grand Theft Auto V continues to have some of the best gaming graphics. This is a game where using a performance GPU with a less capable processor is not recommended. The game works well on the top-end cards from 2015 offering 33fps with higher-end current cards offering 60+fps.

Red Dead Redemption 2

Red Dead Redemption 2 was a bestseller of 2018 and one of the highest-rated games of all time. 2019 saw the launch of an enhanced graphics PC edition. The game requires high-end GPUs for a high-fidelity experience at 60fps but features nearly 40 different graphics settings to customize visuals and performance.
