Battlefield V

This is one of the most CPU-intensive FPS games out there, so it takes some serious hardware to get an ideal 144FPS or even stay consistently above 60FPS. You’ll need a very high-end PC to get those frame rates, but BFV will still put your CPU to work even without them.

The battlefields are full of AI combatants and vehicles to manage all at once, which makes the game incredibly resource intensive on your processor. The complexity of BFV’s combat mechanics is what makes it such a CPU-hog – every single AI character and vehicle has its own set of tasks for the game engine to calculate during gameplay.

The sheer number of calculations per second can easily overwhelm CPUs that aren’t up to scratch – no matter how powerful your graphics card may be – resulting in stuttering frames and slowdowns if your computer isn’t up to task. That’s why we’d always recommend pairing a good GPU with an equally good CPU when playing this title; otherwise you’ll end up bottlenecking yourself before you have time to enjoy the explosive action!

On top of that, many players also opt into modding their copy of Battlefield V either through custom maps or visual enhancements like higher resolution textures or shaders, both things which add extra load onto already struggling CPUs. Add in anti-aliasing settings, motion blur effects and realistic physics simulations (especially if playing with ray tracing enabled) and your poor processor won’t know what hit it!

Make sure you’ve got enough RAM as well as processing power if you’re looking for smooth performance from BFV – anything less than 16GB might cause issues later down the line as more content is added over time. So don’t underestimate just how much power Battlefield V needs from your rig; if you’re looking for optimal performance then make sure both your graphics card and processor are top notch! Otherwise it could be goodbye smooth gaming experience hello frustration central…

World of Warcraft

It may not be as CPU intensive as other games like Battlefield V, but it can still give your processor a good workout during certain moments in the game.

World of Warcraft requires a lot of processing for all the individual units during gameplay, such as when participating in dungeons or raids with large groups of people. The game also puts strain on the CPU when playing in major cities due to all the NPCs present, or during PvP battles with lots of competing players.

All this means that having an up-to-date PC setup is essential for a balanced experience while playing WoW; anything less and you’ll run into issues pretty quickly. In order to get the best performance out of WoW, it’s important to invest in powerful components such as high clock rate CPUs and plenty of RAM.

A modern R5 or i5 should provide ample power for most players’ needs; however, if you’re looking to run more intensive addons or participate in higher level content then an R7 or i7 processor would definitely be beneficial. As far as RAM goes, 8GB should be enough but 16GB is recommended if you’re planning on using multiple programs alongside WoW at once.

Having said that though, even with powerful hardware some players might still struggle to keep up with their desired framerates in WoW due to its frequently changing environment and heavy reliance on complex AI calculations behind the scenes – so bear that in mind too!

Ultimately though, if you have the right hardware setup then you should have no problem enjoying all that World Of Warcraft has to offer without any hiccups!

st cases, but if you’re looking for the best performance then going for one of the higher end CPUs on the market like AMD’s 5600X or 5800X is recommended.

When it comes to huge levels and maps, more processing power is required from your system’s hardware as there is a lot more data to crunch through when rendering a larger environment. The immense size of Warzone’s maps can put extra strain on your CPU compared to other games with smaller maps.

In addition to this, some FPS titles have AI opponents which also rely heavily on your CPU cycles – although this isn’t really an issue in Warzone as all opponents are real players who are highly capable of outsmarting any artificial intelligence!

For serious gamers looking for the ultimate in performance, having a high-end processor can make all the difference when trying to sustain consistently high frame rates at 144Hz or even 240Hz resolutions. Having said that though, even modern mid-range processors should be able to handle Warzone without too much trouble provided they’re paired with a GPU that can cope with such frame rates.

So if you’re looking for an intense gaming experience that will test both your skills and PC components alike, then why not give Call of Duty: Warzone a try? You won’t regret it – unless you encounter lag issues due to insufficient hardware resources!

Mortal Kombat 11 is one of the most CPU intensive games currently out there.

It requires powerful hardware to ensure smooth gameplay and good performance.

The game’s physics engine is complex and requires a lot of processing power from the CPU for physics calculations and AI behavior.

In addition, the game also uses many graphical effects such as lighting and shadows which can put an additional load on the GPU if not optimized properly by developers.

This makes it necessary for gamers who want to get the best experience out of their gaming PCs to invest in more powerful CPUs that can handle these intensive tasks efficiently.

The added bonus with this game is that it has plenty of replayability value due its expansive character customization options as well as its deep combat system which allows players to develop their own unique strategies while playing online or against CPU opponents alike.

As such, playing Mortal Kombat 11 means investing in a powerful enough setup so you can enjoy every single frame without worrying about lag or stuttering issues caused by weak hardware components.

A modern Ryzen 5 or i5 processor should do just fine but if you’re looking for something even more capable then consider going with an Intel Core i7 or AMD Ryzen 7 processor instead – both are excellent choices when it comes gaming PCs specifically built around this particular title’s demands on hardware resources.

To sum up: Mortal Kombat 11 is one of those games that require some serious horsepower under its hood in order for gamers to truly appreciate what it has to offer from a technical standpoint – especially when played online against real human opponents where split second decisions might mean victory or defeat!

Investing in a higher end processor could be well worth it if sharp visuals and smooth performance are what you’re after!


We hope this list of the most CPU-intensive games has given you a better understanding of what type of game can put your system’s processor to the test.

Whether you’re looking for an immersive strategy experience or an action-packed shooter, there are plenty of options out there that will make sure your CPU is running at its peak performance.

So don’t let a slow computer stop you from playing – choose one of these games and get ready to be blown away by the power of your processor!
