Really useful CPUs and GPUs for 90Hz, 120Hz, 144Hz (Low – Extremely Settings)

Final Up to date: January 13, 2022
If there ever was a recreation worthy of upgrading or constructing a gaming PC for, Half Life Alyx is it. As a Half Life fan who fondly remembers HL1 as one of many very first PC video games I ever performed as a child, and likewise as a agency believer in VR (and AR) being the inevitable way forward for primarily all leisure, when Alyx launched to overwhelmingly optimistic reactions I used to be relieved and so glad Valve lived as much as the large pre-launch hype.
Not that I ever doubted them, as they’re in Uncommon firm as builders in spite of everything (a reduce above the remaining). Nevertheless you take a look at it, the sport is a masterpiece that does not come round usually, and a must-play whether or not you are a Half Life fan or not. It takes lots to set off me, however when you personal a VR headset and have not performed it, I am actually triggered.

However on a critical observe, Alyx is properly and really the greatest VR recreation of all time (to this point). Should you had been ever on the fence about VR and its future, experiencing it first-hand will certainly shift your perspective and open your eyes to the limitless potentialities of this thrilling new medium (watching gameplay movies does not rely, because it simply can not do the expertise justice). However let’s reduce the hype earlier than I begin sounding like I am auditioning for Valve’s advertising and marketing staff, and let’s get into particular {hardware} necessities for all ranges of efficiency.
Regardless of which body price you search, and at which visible settings, I’ve accomplished the in depth analysis so that you can share my findings on selecting the most effective worth elements for a easy Alyx expertise (beginning with 90Hz which is what most VR headsets run at, after which 120Hz and 144Hz for the headsets that help these quick modes). If you need full PC construct examples primarily based on the present market to associate with this information (not simply CPU and GPU suggestions), take a look at the greatest PC builds for the cash collection alongside this information.
Minimal Necessities for Half Life Alyx
Let’s first go over the official naked minimal specs offered by Valve themselves if you wish to merely run the sport. A GTX 1060 6GB or RX 580 graphics card, paired with a modest i5-7500 or R5 1600 processor and at the least 12GB of RAM will assist you to run the sport comparatively okay-ish on low settings. However to keep away from dropped frames and stuttering, you undoubtedly wish to intention at the least a bit greater together with your {hardware} in any other case it is not going to be easy throughout.

That stated, one of many million nice issues about Half Life Alyx is Valve have expertly optimized it very properly to run surprisingly properly on mid-range setups, so relying on the efficiency degree you are after (90FPS, 120FPS, and so forth), it’s possible you’ll not want as beefy a PC as you may think. Relative to how visually beautiful the sport is with its painstaking consideration to element and meticulously crafted environments, the sport runs like a champ.
Half Life Alyx System Necessities
Minimal CPU: Intel Core i5-7500 or AMD Ryzen 5 1600
Minimal GPU: NVIDIA GeForce GTX 1060 6GB or AMD Radeon RX 580 8GB
Minimal VRAM: 6GB
Minimal RAM/Reminiscence: 12GB
Onerous Disk Storage Area: 67GB
Working System: Home windows 10
Supply: Steam

Low-cost PC Builds for Half Life Alyx (90Hz Low/Med)
The most typical refresh price for PC VR gaming lately is 90Hz, which is supported by all of the present greatest PC VR headsets. Due to this fact, reaching 90FPS efficiency ought to be your goal, and ideally you wish to keep above 90FPS always to keep away from dipping below. Everytime you dip below your VR headset’s refresh price when gaming, the software program quickly allows a VR interpolation method known as asynchronous reprojection that principally cuts your body price in half and renders the sport at half your headset’s refresh price to keep away from enter lag (so, 45FPS if gaming at 90Hz).
Not the top of the world in case your recreation kicks reprojection into gear each every now and then, but it surely’s not very best if you would like the smoothest VR expertise as some folks will discover the distinction between 90FPS and a reprojected 45FPS, particularly when you’re vulnerable to movement illness. Dropped frames in VR is extra noticeable total in comparison with flatscreen gaming, which is why you wish to use the correct settings on your specific {hardware} to keep away from it as a lot as you may.
Valve lists a GTX 1060 6GB and RX 580 8GB as minimal beneficial GPU for Half Life Alyx, together with an older Ryzen 5 or Intel i5, however these specs is not going to offer you a pleasant clear 90FPS and above always within the recreation (not even on the bottom settings). For 90FPS on low settings, you will want a greater graphics card.
Talking of decrease settings, don’t be concerned as a result of Alyx seems to be completely improbable irrespective of the graphics settings, and it is genuinely onerous to inform the distinction between them until you actually cease and actively search for the distinction, which may truly nonetheless be tough to discern in most scenes until you are evaluating say low vs extremely settings.
In different phrases, low vs medium settings, or medium vs excessive settings – it is impossible you’ll discover the distinction. Even low vs excessive and low vs extremely is hard to identify, and I communicate from expertise right here. Once I performed via the sport final 12 months, I used a RTX 2060 Tremendous, and although I may simply run medium settings decently, I settled on low settings to keep away from reprojection all however utterly, and each single facet of the sport seemed simply superb. Once I examined different settings – even extremely – I hardly observed a distinction in visible high quality.

Remember this isn’t the case with most video games (VR or common), therefore why I am making a degree about it in order that individuals are conscious to not be scared off by avoiding or suspending enjoying Alyx just because your PC is not ok to run it at excessive or extremely (within the concern that you will “smash” such a monumental recreation). In lots of PC video games that boast stunning graphics, there can certainly be a stark distinction between settings the place enjoying on low may bitter the expertise considerably. However in Alyx, due to Valve, that is simply not a factor.
I had that concern getting into, as I really feel a recreation as uncommon as this ought to be treasured and skilled to its full potential, however that concern was rapidly squashed as soon as I rigorously in contrast low vs medium vs excessive vs extremely settings. Decrease settings took nothing away from the immersion: the environments, textures, results, character fashions, and so forth all look beautiful irrespective of which settings are used.
So, primarily based on the present technology of graphics playing cards – RTX 3000 and RX 6000 collection – for flawless 90FPS efficiency on medium settings, the most effective GPU for Half Life Alyx is a RTX 3060 or RX 6600 XT. These newest mid-range playing cards from NVidia and AMD also can do excessive settings fairly properly, however not flawlessly (you will get the occasional dropped frames and slight reprojection). For low settings, a RTX 2060 Tremendous or RX 5700 XT will probably be flawless, although you could possibly use these for medium when you do not thoughts the occasional dip below 90FPS.
Greatest Worth Alyx Specs for 90FPS (LOW/MEDIUM)
CPU: AMD Ryzen 5 3600 / Ryzen 3 3300X or Intel Core i5 12400 / 11400 / 10400
GPU: NVIDIA GeForce RTX 3060 12GB / RTX 2060 Tremendous 8GB or AMD Radeon RX 6600 XT 8GB / RX 5700 XT 8GB
RAM: 16GB DDR4 (2x8GB, 3200MHz)
Going additional down within the graphics chain to a RTX 2060, GTX 1660 Tremendous, GTX 1660 Ti, RX 5700, or RX 5600 XT can be okay for low settings if you cannot afford a 3060 or 6600 XT (or 2060 Tremendous or 5700 XT), particularly if it is the 5700 or 2060 that are the quickest playing cards of that bunch.
But I am unable to advocate these cheaper playing cards if you wish to assure a really easy expertise throughout the sport, and likewise with the unbelievable mods that are extra demanding than the primary recreation since they’re much less optimized (and the mods are completely to not be missed for my part and I contemplate them integral to the general Alyx package deal). As a result of Alyx can actually eat up that VRAM simply, playing cards with 6GB of VRAM are effective if on a good finances, however 8GB playing cards are extremely beneficial if you would like the most effective expertise.
As for selecting the most effective CPU for Half Life Alyx and getting essentially the most bang on your buck, I extremely advocate a Ryzen 5 3600 or a current Intel Core i5 just like the 10400 or 11400 (not a lot distinction between the 2). These CPUs are greater than sufficient for a constant 90FPS in Alyx, so no want for a stronger CPU until you are eager to run 120Hz or 144Hz. As a substitute of spending extra to purchase a greater CPU than the 3600 or 11400, I’d use that cash on a greater graphics card as an alternative (once more, until it is for 120Hz/144Hz during which case your CPU necessities are greater).
In actual fact, you could possibly go cheaper on the CPU when you wished and nonetheless have a easy trip in Alyx for essentially the most half, resembling getting a Ryzen 3 3300X or Intel Core i3 10100 since these processors usually are not far behind the Ryzen 5 3600. However personally, I’d not, since these CPUs solely have 4 cores and for Alyx I undoubtedly advocate a 6-core processor. Half Life Alyx makes efficient use of a number of cores, and might hold a 6 and even 8-core CPU busy.
You particularly do not wish to go too low-cost in your CPU if you wish to play the entire nice mods after ending the primary marketing campaign, as a result of Alyx mods might be extra CPU intensive since most modders understandably lack the optimization prowess (or time) of the geniuses at Valve.
Greatest PC Builds for Half Life Alyx (90Hz Excessive/Extremely)
Should you’re planning the very best PC construct for Half Life Alyx at 90Hz, to succeed in that golden 90FPS and above all through the sport on excessive or extremely settings, under are the most effective worth GPUs to get you to that promised land. CPU suggestions keep the identical as they had been for low/medium settings above, as a result of greater graphics settings predominantly place extra load in your GPU, and if a sure CPU can hit 90FPS on low settings it’s going to be effective to do the identical at greater settings.
In most VR video games, at 90Hz having a CPU bottleneck is unlikely when utilizing any half-decent fashionable CPU resembling a Ryzen 5 3600, and also you’re virtually all the time going to be GPU-bound (as in, restricted in efficiency by your GPU, which is what you need). In different phrases, a Ryzen 5 3600 or equal CPU is totally effective to max out Half Life Alyx, and won’t bottleneck a RTX 3070 or RX 6800, so there isn’t any have to spend extra in your CPU until you need flawless 120Hz or 144Hz efficiency (put that cash in direction of the graphics card as an alternative).
Greatest Alyx Specs for 90FPS
CPU: AMD Ryzen 5 3600 / Ryzen 7 3700X or Intel Core i5 12400 / 11400
GPU (HIGH): NVIDIA GeForce RTX 3060 Ti / RTX 2070 Tremendous 8GB or AMD Radeon RX 6700 XT 12GB
GPU (ULTRA): NVIDIA GeForce RTX 3070 / RTX 2080 Tremendous 8GB or AMD Radeon RX 6800 16GB
RAM: 16GB DDR4 (2x8GB, 3200MHz)

Final PC Builds for Half Life Alyx (120Hz / 144Hz)
Whenever you transfer to 120Hz VR gaming – supported by the Oculus Quest 2 and Valve Index – you wish to take a look at investing in a sooner processor if attainable as a result of hitting such excessive body charges in Alyx would require a stronger CPU than is required for 90Hz. Particularly for a comparatively CPU intensive recreation resembling Half Life Alyx.
Positive, Alyx is way more GPU intensive than CPU intensive total, and there are VR video games which can be a good bit extra CPU intensive than Alyx (like Boneworks). However hitting 120FPS persistently throughout the board throughout the entire of Alyx’s marketing campaign will take a reasonably quick CPU. The Ryzen 5 5600X is the most effective worth high-end gaming CPU total proper now, and is sufficient grunt for 120FPS in Alyx from what I collect. Paired with an RTX 3080 or RX 6800 XT and also you’re golden, even on maxed settings.
Greatest Alyx Specs for 120FPS (ULTRA)
CPU: AMD Ryzen 7 5800X or Intel Core i5 12600K / i9 10900K / i9 9900K
GPU: NVIDIA GeForce RTX 3080 10GB or AMD Radeon RX 6800 XT 16GB
RAM: 16GB DDR4 (2x8GB, 3200MHz)
Aiming to succeed in a constant 144FPS within the Valve Index’s unique 144Hz mode will increase each CPU and GPU necessities additional, so for the most effective expertise to keep away from dipping below 144FPS it is merely, and fairly clearly, a matter of getting the most effective gaming CPU and GPU you may afford.
Greatest Alyx Specs for 144FPS (ULTRA)
CPU: AMD Ryzen 9 5900X or Intel Core i9 12900K / 11900K / i7 12700K
GPU: NVIDIA GeForce RTX 3080 Ti 12GB / RTX 3090 24GB or AMD Radeon RX 6900 XT 16GB
RAM: 32GB DDR4 (2x16GB / 4x8GB, 3600MHz)
Observe on VR Decision Settings:
Please remember all suggestions on this information assume you aren’t growing both the SteamVR render decision setting or any in-game decision scaling setting. Should you improve these past their defaults, your GPU will probably be hit more durable and you’ll require beefier specs than those I urged.
