Sim Racing PC: Triple screens, wheel bases and what you need

A sim racing setup is 3 purchases, not one. The PC, the screens, and the wheel and pedals. Most people underestimate the last two and overestimate the first, then wonder why the whole thing feels less convincing than it looked.

When looking to set up a sim racing rig, it is best to start with what monitor setup you are aiming for, the resolution and refresh rate you are trying to reach consistently, and what wheel + pedals you want, then figuring out what the PC needs to reach that. If this falls outside of your budget, then either some small adjustments need to be made, curbing your expectations, or waiting until you can afford more is the next decision. If you're running a single screen, a mid-range to slightly high-end gaming PC handles sim racing comfortably depending on what resolution and refresh rate you’re aiming for. If you're running a triple monitor setup, the graphics card becomes the biggest cost in the build.

Sim racing is one of the few things where the display choice changes the PC spec more than the games do. Count the pixels and it's obvious. A single 1080p screen is about 2.1 million pixels. Triple 1080p is roughly 6.2 million, which is more work than a single 1440p display. Triple 1440p is around 11 million, comfortably more than 4K. The graphics card doesn't care that the pixels are spread across 3 panels rather than 1, it just has to draw all of them.

So the honest ordering.

Single ultrawide: The value option, and what a lot of people settle on. A 34 inch 3440x1440 panel gives you useful peripheral vision without tripling the rendering load, at around 5 million pixels, so a mid-range card handles it.

Triple screens: Genuine peripheral vision, which matters for placing the car on corner entry and for racing wheel to wheel. It's the setup most serious sim racers end up with, and it costs 3 times the panels, needs a stand or rig to mount them, and requires a graphics card that can drive them.

Single flat screen: Works perfectly well to start, and plenty of quick drivers use one. You lose the sense of the car rotating underneath you that triple screen setups give, at a fraction of the cost.

A curved monitor helps when it’s an ultrawide because the edges are otherwise far off-axis. On triple screen setups, angling the outer screens does the same job, so the curve matters less.

If you're weighing this up, look at 34 inch monitors alongside the wider gaming monitor range.

Consistency matters more than peak frame rate. You're reacting to the car at speed, and a stutter mid-corner is worse than a lower but steady frame rate, so frame time consistency is the thing to chase. A solid 90fps that never wobbles beats an average of 130fps with drops.

The processor handles the physics: tyre models, suspension, aerodynamics, and the AI or online cars around you. A full grid asks considerably more of the CPU than hot-lapping alone, which is why performance at a race start looks nothing like performance in practice.

The graphics card handles the pixels, and with triple screen setups, that's the dominant cost, scaling almost linearly with the number of screens.

It’s worth knowing which racing sim you are looking to spend most of your time on before you spec anything. iRacing is comparatively light and runs well on modest hardware, which is part of why it has the competitive scene it does. Assetto Corsa Competizione is heavy, particularly at night and in the rain with a full grid.

Wheel bases come in three broad types. Gear-driven units are the entry point, cheap and noticeably notchy. Belt-driven bases are smoother and were the mid-range standard for years. Direct drive puts the wheel straight onto the motor shaft with nothing in between, which is why the detail coming through is so much better. Direct drive strength is quoted in Newton metres, and entry-level units around 5 to 8Nm are more than enough for most people, with the very strong bases existing mainly for people running heavy formula cars.

One practical warning: a powerful direct drive base will flex or move a desk. If you're going past entry level, you will need a rigid mount or a proper rig, and that cost is part of the wheel decision rather than an optional extra.

Pedals are an upgrade people often forget about or think about last, but they can end up being just as expensive as the wheel. Pedals come in 4 main types: Pentiometer/Hall Effect pedals measure the distance the pedal travels while pressed. These are the entry-level budget pedals as real car brakes respond to pressure, making these feel a bit unnatural. A load cell brake pedal measures how hard you press rather than how far you push, which is how a real brake works, allowing for a player to build muscle memory for precise braking. This makes load cell brakes the mid-range standard pedals. Hydraulic pedals are the high-end pedals, using fluid dynamics inside a master cylinder to replicate the exact resistance and feel of a real race car. Lastly, there is the active pedals for professionals and players with unlimited budgets. Active pedals have built-in electric motors that provide direct force feedback and dynamically changes resistance to replicate ABS vibrations and simulating tire lockups.

None of this is PC hardware, and it's the part that decides whether the setup feels right, so budget for it before you spend everything on the tower.

These rough specs are aiming for 90-144fps for their corresponding setups/resolution.

In general, always spec the PC to have 32GB memory minimum, and try to aim for AMD Ryzen X3D CPUs; they are more expensive, but the massive L3 cache is very beneficial to sim racing in-game performance.

If you're building from nothing, get a single good screen and decent pedals first, and add screens later. Triple screens setup are easy to expand into if the graphics card has the outputs and the headroom. Starting with three cheap panels and a wheel you'll replace within a year is the more expensive route to the same place.

Our racing sim PCs are configured for this workload, and the wider simulator range covers flight sim as well. If you already know your screen setup and want to set the CPU and GPU balance around it, the PC configurator lets you do that.
