DCS – Best PC Setup/ Build (2021)

DCS is a demanding game, especially if you intend to play in VR. However, it is also one of the most rewarding experiences on PC. DCS especially appeals to mature audiences who have the patience to to study complex systems to fly these highly capable combat aircraft like the way they are meant to. 

In addition to time, you also need to invest in the necessary hardware. This can be quite confusing and frankly I too was baffled when I first started to build my DCS rig back in 2014. Since then, I have tried out dozens of hardware options including CPUs, GPUS, VR headsets, monitors, joysticks etc.

These are my top recommendations for a highly capable DCS rig based on my experiences over the years. This is the top-end for both VR and pancake (monitor) gaming.

1. CPU

The 10900K is the best CPU for DCS right now. This is because DCS still mostly relies on a single core and the 10900K has the highest single core performance amongst consumer grade CPUs. The 10900 can overclock to 5+ GHz and that’s the best you can get right now. Just make sure to provide ample cooling using a 240mm or 360mm radiator. AMD’s Ryzens perform better for multi-core and the 5000 series match or even exceed Intel in some cases, but I haven’t found that to be consistent in DCS. They also seem to be in limited supply and are priced much higher. Still, if you prefer AMD, go for the 5900X  in the premium category.

For midrange options, I recommend the Intel 9600K  or the Ryzen 5600X . For more options, check out the DCS CPU guide here.

2. Graphics Card

EVGA GeForce RTX 3090 FTW3 Ultra Gaming, 24GB GDDR6X, iCX3 Technology,...
  • Real boost clock: 1800 MHz; Memory detail: 24576 MB GDDR6X.
  • Real-time ray tracing in games for cutting-edge, hyper-realistic graphics.

The Nvidia 3090 is the best option right now and the only graphic card worthy of being paired with your premium CPU. The 3080 is the only other card that comes close right now so this is a more straightforward choice. The only reason not to pick a 3090/3080 is cost and availability in that case, there are some cheaper options that I have reviewed in this article.

3. RAM

Corsair Vengeance LPX 32GB (2x16GB) 3200MHz C16 DDR4 DRAM Memory Kit...
  • Hand-sorted memory chips ensure high performance with generous overclocking headroom
  • Vengeance LPX is optimized for wide compatibility with the latest Intel motherboards

DCS does benefit from having 32 GB of RAM if you can provide it. This will really help with the loading times. It works with 16 GB as well but then some of the assets have to be loaded form the page file or form the SSD which can affect performance especially during loading.

It is very important to pick high speed/ low latency RAM though. Not all RAM are created qual. The one I have recommended is the 3200 MHz DDR4 RAM which is the best available. There are 2133MHz and 2400 MHz options too so make sure you are selecting the right options before you buy!

4. SSD

  • Continuity tester/Wire tracer

DCS easily uses upwards of 200 GB of space with all modules. Ideally, you want all your games on a separate SSD than your operating system because they both will try to access the disk simultaneously and this can affect gaming performance. Its not that big of a deal but it is best practice to put more demanding games on a secondary SSD.

As always, faster is better. The NVMe is a pretty good option but I personally have used over a half a dozen Samsung Pros/ Evos without issue. Some of them are 8 years old now and still kicking! Quality stuff.

5. Joysticks/ HOTAS/ Controllers

  • Dual throttles, featuring a Metal hand rest, Locking system, Adjustable friction system, Realistic...

The Thrustmaster Warthog is my personal recommendation and I ahve been using it for 7+ years now. It shows no sign of quitting. If you are looking for mid-range or budget options, use this guide to find the one you want for DCS.

6. Rudder Pedals

  • Self-centering pedals with adjustable damping / Foot rests adjust to fit all sizes and include...
  • Precise rudder and braking control / Tension adjustment - choose resistance to suit the way you fly

I recommend the Logitech G PRO Flight Rudder Pedals. I feel it hits the sweet spot in terms of quality and price. There are other more expensive options available, but they are several times more expensive. You would honestly be better off putting that money towards a better CPU, graphics card or VR Headset really.

7. Monitor

I have been using ultrawide monitors for a while now and the Alienware is my top recommendation followed by the Asus. They both have G-sync and an IPS panel which I consider essential for gaming. They also go up to 120 Hz which is the minimum I recommend.

They are both more or less the same on paper. In practice, the difference between them is so negligible that I was frankly unable to make a judgment. So pick the one which is cheaper or the brand you like better. I like both Asus and Alienware.

I have used triple monitors as well and I’d take a single ultrawide over a multimonitor setup any day.

TrackIR is essential if you are planning on using a monitor!

8. VR Headset

The HP Reverb G2 is clearly the best consumer grade VR headset for DCS and all other sims right now. It has a much clearer screen not just on paper, but in practice as well. The Quest 2 is a decent mid-range option if the Reverb is out of your budget or is not available in your country.

Headset Resolution (per eye) Total Pixels (both eyes)
Reverb 2160 x 2160 9,331,200
Quest 2 1832 x 1920 7,034,880
Index 1440 x 1600 4,608,000
Cosmos Elite 1440 x 1700 4,896,000
Vive Pro 1440 x 1600 4,608,000
Rift S 1280 x 1440 3,686,400
Vive 1080 x 1200 2,592,000

A VR Headset is a significant investment so take some time to and read my in-depth review for DCS here.
