How Much RAM For VR? You Need This Much Memory

RAM is essential for VR. But then, how much RAM for VR is enough? This will depend on several factors, particularly the game you’re playing. 

If you’re playing a game that boasts a lot of physics simulations and an open world, then you’ll need a lot of RAM, GPU, and even CPU. Yes, CPU and GPU are essential too. You’ll require a powerful GPU and stable CPU to get the desired FPS. 

As with any game, having more RAM and other essential hardware is a big boost. Virtual Reality (VR) will run smoother, and you’ll get a better user experience.   

Here, we will explain all the things you must know about RAM choice for VR. After reading, we hope you’ll have the capacity to make an informed decision. 

How Much RAM For VR Is Enough? 

Let’s assume this question is for gamers and VR developers. Individuals in both categories need enough RAM space. Why? You will be running many applications, so choosing an adequate amount of RAM is essential. 

For VR gamers, 16GB RAM is a good option for those that play 1080p at 60FPS. So, before you claim your PC is VR-ready, check the RAM and other relevant hardware (GPU and CPU). 

Your computer has to be super fast to support VR applications and goggles. Of course, it would be interesting to have your applications and hardware working fast. This way, you’ll enjoy VR games. 

We said 16GB RAM is a reasonable option, but 32GB is better if you have the budget. So go ahead and invest in 32GB memory. Why? With this memory size, your applications will have plenty of headroom. 

Another reason we recommend 32GB RAM is to make your system future-proof. With this much space, you can run any current VR and won’t need an upgrade for the next 5years or so. 

Are you a VR developer? We recommend getting 64GB RAM or more, based on the full suite of software you intend to use. 

Are 8GB and 4GB RAM ideal options for VR? Well, the truth is some of the VR headsets out there require a minimum of 8GB RAM. The only exceptions are the HTC Vive Pro and HTC Vive Pro Eye. These two VR headsets can run on a minimum of 4GB RAM. 

A Handy Tip: You need a minimum of 8GB RAM to run the HTC Vive Cosmos VR headset. 

Is There A Performance Increase When You Upgrade From 16GB RAM To 32GB RAM?

Without mincing words, you need enough memory for VR. However, if you’re familiar with VR, you’ll know it’s too demanding hardware-wise. Thus, even with 32GB RAM, you may have to it to low settings to achieve 90 FPS. 

While getting good RAM is essential, your primary focus should be GPU. Virtual Reality is super immersive. Therefore, the right step is to acquire a powerful GPU and then turn everything down to low. This way, you’ll achieve 90 FPS, as explained earlier. 

How To Tell If Your PC Is VR Ready

Whether you aim to play virtual reality games or develop virtual reality applications, having the proper hardware matters a great deal. In reality, this means splashing the cash on a high-end PC.

Buying the best gaming PC available will put a big dent in your wallet. Besides, the gaming PC the industry claims is the best today might become average in a year or even less. 

Technology keeps improving every day. And tech companies are always in a hurry to produce an upgrade on their previous releases. 

What is the point we’re trying to make? If you plan to play VR games or create one, do this. Focus on the hardware when custom-building your computer. 

We’re going to discuss hardware requirements for computers used for playing VR. Here is what you need to know. 

How Much RAM Is Enough To Run VR?

When deciding how much RAM you need for VR gaming or other applications, remember that the more, the better. Most VR headsets require a minimum of 8GB. However, going higher, say 16GB memory, will be wise. When you have enough memory, your games will run smoothly. 

Now, where does 4GB memory stand? Know that most VR headsets can run on 4GB RAM. Examples include HTC Vive Pro, including the HTC Vive Pro Eye. 

And as we said before, the HTC Vive Cosmos requires only 8GB RAM. 

How Much CPU Is Enough To Run VR?

Besides RAM, CPU and GPU are the two essential pieces of hardware to consider when buying a PC for VR. We can even argue that both are more important. 

How much CPU is enough for VR gaming? Whether you’re using the HTC, Valve, or Oculus VR headset, purchasing a PC with more computational power is essential. Here are the basic CPU requirements for the headsets mentioned above. 

You can get the Intel i5-4590 or greater for VR gaming. This should get the job done. Note also that the benchmark is 1600+. 

If you can’t get the above CPU, use the AMD Ryzen 3 PRO 22000GE. Other options include AMD Ryzen 5 2400GE and AMD FX 8350, or you can go higher with the budget. 

How Much GPU Is Enough To Run VR?

As said before, GPU is critical hardware to consider when choosing a computer for VR. You need a powerful GPU to offer the best render solutions to your VR apps and enjoy a much better gaming experience. 

Your GPU renders two displays, one for each eye. And as said earlier, a powerful GPU will deliver desirable output. Similarly, an average GPU will render an average or poor-quality output. You want to avoid having such an experience when playing VR. 

A Handy Tip: You can buy the minimum recommended GPU or higher. Whichever is the case, be ready to keep everything at low settings. This way, you can achieve your desired 90 FPS consistently. 

Here are the GPU requirements for the Valve Index VR headset. Remember, this is easily one of the best VR headsets to acquire if you’re seeking high-end PC gaming.  

The minimum GPU required for the Valve Index is GTX 1070 or higher. The benchmark is 10570+, while the alternative options include Pro Vegas 64, GTX 900, and Radeon.   

The minimum GPU requirement for Oculus Rift S and HTC Vive includes the Nvidia GTX 970. However, you can go higher, but keep in mind that the benchmark is 9563+. 

The alternatives are also apparent. If you can’t get your hands on the Nvidia GTX 970, you can equally obtain the GeForce GTX 1060, Radeon R9 Fury, or the Radeon R9 390X. 

 How Do You Know Your PC Is VR Ready? 

Not every PC or computer is VR-ready. Have this in mind. In addition, note that using a PC that isn’t VR-ready for playing Virtual Reality games will leave you bored. In a nutshell, you won’t enjoy playing virtual Reality. 

You can determine if your PC is VR-ready by using a piece of software. Most people may depend on written statistics, but using software provides more insight. 

The SteamVR performance is one tool to measure your PC’s VR readiness, and it is super fast. In 2 minutes, you’ll get the result of this test to make your decision.
