Flight Sim PC Build Guide: MSFS 2024 on a Budget

By Joel Mikkelsen, Owner — Eagle Gaming | Updated 3 April 2026 | 9 min read

Microsoft Flight Simulator 2024 is one of the most demanding applications you can run on a PC. It needs a strong CPU, plenty of RAM, fast storage, and a capable GPU — all at the same time. Here's how to build a flight sim rig that actually runs well without blowing your budget on the wrong components.

Why Flight Sims Are Different from Regular Gaming

Most games are GPU-bound — throw a faster graphics card at them and performance scales linearly. Flight simulators break that rule. MSFS 2024 is simultaneously:

  • CPU-intensive: Air traffic, weather calculations, terrain streaming, and avionics simulation all hammer the CPU. Single-thread performance matters more than core count.
  • GPU-intensive: Rendering detailed terrain, clouds, and volumetric weather at high resolution is demanding. VRAM usage is high.
  • RAM-hungry: The sim routinely uses 20-24GB when streaming detailed scenery. Add-ons push this higher.
  • Storage-dependent: Terrain data streams continuously from disk. Slow storage means scenery pop-in and stuttering.

This means you can't just follow standard gaming build advice ("spend 50% on the GPU"). Flight sims need a more balanced build.

The Components That Matter Most

CPU: Single-Thread Performance Is King

MSFS 2024's main thread handles the core simulation loop — ATC, weather, terrain loading. This thread runs on a single core and is almost always the bottleneck at lower resolutions. You want the fastest single-thread CPU you can afford.

The current best options for flight sims in 2026:

  • Best value: AMD Ryzen 5 9600X — 6 cores, excellent single-thread performance, pairs well with budget builds
  • Best overall: AMD Ryzen 7 9800X3D — the 3D V-Cache gives it a measurable edge in flight sims due to the large working data set
  • Intel alternative: Core Ultra 7 265K — strong single-thread, slightly behind the 9800X3D for flight sims specifically

Avoid spending on Ryzen 9 or Core Ultra 9 for flight sims specifically. The extra cores don't help MSFS, and the money is better spent on GPU or RAM.

GPU: VRAM Matters More Than You Think

At 1080p, flight sims are often CPU-limited, so a mid-range GPU is fine. At 1440p and above, the GPU becomes the primary bottleneck. VRAM is critical — MSFS 2024 at high settings with add-on scenery can use 10-12GB of VRAM.

  • 1080p medium-high: RTX 5060 (8GB) — adequate but VRAM will be tight with scenery add-ons
  • 1440p high: RTX 5070 Ti (16GB) — the sweet spot for serious flight simmers. 16GB VRAM handles everything
  • 4K ultra: RTX 5080 (16GB) or RTX 5090 (32GB) — for the fully committed. Pairs with TrackIR or VR headsets

RAM: 32GB Minimum, 64GB If You Can Stomach the Price

This is one area where flight sims genuinely differ from standard gaming advice. While 32GB is sufficient for most games, MSFS 2024 regularly uses 20-24GB of system RAM. Running add-on weather engines, ATC tools, or Navigraph charts alongside pushes that higher.

Here's the uncomfortable reality in 2026: DDR5 prices have gone through the roof. The "Ramageddon" — driven by AI data centres hoovering up global DRAM supply for inference servers — means 64GB DDR5 kits now cost significantly more than they did a year ago. A 64GB DDR5-6000 kit that was $250 in 2025 can now run $400-500+.

There is a light at the end of the tunnel. Google's TurboQuant compression algorithm (announced March 2026) reduces AI memory requirements by up to 6x, which could ease demand pressure on DDR5 from data centres. DDR5 retail prices have already started pulling back slightly — 32GB kits that peaked near $490 are now closer to $370. Analysts expect meaningful normalisation by late 2026 or 2027, but nobody's calling the bottom yet.

Our recommendation: start with 32GB DDR5-6000 and budget for a future 64GB upgrade when prices settle further. 32GB handles MSFS 2024 at stock settings. You'll notice occasional stuttering with heavy add-ons, but it's playable. If you're running third-party scenery, weather engines, and charts simultaneously, 64GB is worth the premium — just go in with eyes open on the current cost.

Storage: NVMe Is Non-Negotiable

MSFS 2024's base install is over 150GB. Add-on scenery (Orbx, FlyTampa, MK Studios) can push your total well past 500GB. The sim streams terrain data continuously during flight — slow storage means blurry ground textures and buildings popping in late.

  • Minimum: 1TB NVMe PCIe 4.0 SSD (Samsung 990 Pro, WD SN850X)
  • Recommended: 2TB NVMe for the sim + add-ons, separate boot drive optional but not necessary
  • Avoid: SATA SSDs and HDDs for the sim install. The sequential read speed matters for terrain streaming.

Three Flight Sim Builds for Australian Budgets

Budget Build: $2,500-3,000 AUD — 1080p Medium-High

Gets you in the air with acceptable performance. MSFS 2024 at 1080p medium-high settings, 30-40fps in dense areas, 50-60fps in cruise.

  • AMD Ryzen 5 9600X
  • 32GB DDR5-6000 (upgrade to 64GB later when RAM prices settle)
  • RTX 5060 8GB
  • 1TB NVMe PCIe 4.0
  • Quality air cooler (Thermalright Peerless Assassin 120)
  • 650W 80+ Gold PSU

This aligns closely with Eagle Gaming's Vanguard Series. With current DDR5 pricing, starting at 32GB and upgrading later is the smart play.

Sweet Spot Build: $4,500-5,500 AUD — 1440p High

Smooth 1440p with high detail. 40-50fps in dense cities, 60fps+ in cruise. This is the tier most serious flight simmers should target.

  • AMD Ryzen 7 9800X3D
  • 32GB DDR5-6000 (64GB if budget allows — expect $400-500+ for the upgrade thanks to Ramageddon pricing)
  • RTX 5070 Ti 16GB
  • 2TB NVMe PCIe 4.0
  • 240mm AIO liquid cooler
  • 850W 80+ Gold PSU

This matches Eagle Gaming's Apex Series specs — purpose-built for this kind of workload.

No-Compromise Build: $7,000-9,000 AUD — 4K or VR

For pilots running 4K monitors, ultrawide setups, or VR headsets (HP Reverb G2, Meta Quest Pro with link). Frame rates stay smooth even in photogrammetry cities.

  • AMD Ryzen 7 9800X3D (or Core Ultra 9 285K if also doing video editing)
  • 64GB DDR5-6000 (non-negotiable at this tier — the budget absorbs the Ramageddon tax)
  • RTX 5080 16GB (or RTX 5090 32GB for VR)
  • 2TB NVMe PCIe 5.0 (Samsung 9100 Pro)
  • 360mm AIO liquid cooler
  • 1000W 80+ Gold PSU

This builds on Eagle Gaming's Titan Series platform with flight-sim-specific optimisations.

What About Peripherals?

A flight sim rig isn't complete without the right input devices. This is beyond Eagle Gaming's build scope, but worth budgeting for:

  • Joystick: Thrustmaster T.16000M ($80-100) for budget, VKB Gladiator EVO ($250-300) for serious use
  • Throttle quadrant: Thrustmaster TWCS ($100) or Honeycomb Bravo ($350) for airliner flying
  • Rudder pedals: Optional but recommended. Thrustmaster TFRP ($150) or MFG Crosswind ($500+)
  • Head tracking: TrackIR 5 ($250) transforms the experience. Budget alternative: SmoothTrack app ($15) with a phone

Common Mistakes to Avoid

  • Buying a Ryzen 9 / Core Ultra 9 for flight sims: Extra cores don't help. The 9800X3D beats both in MSFS thanks to 3D V-Cache.
  • Blowing the budget on 64GB RAM at current prices: With Ramageddon pricing, that extra 32GB could cost you a GPU tier. Start with 32GB and upgrade later — the stuttering from 32GB is occasional, not constant.
  • Using a SATA SSD: The read speed difference between SATA (550MB/s) and NVMe (7000MB/s) directly impacts terrain streaming quality.
  • Ignoring cooling: MSFS 2024 sustains high CPU loads for hours at a time (unlike most games which spike and drop). Your cooler needs to handle sustained loads, not just peak bursts.
  • Buying 128GB RAM: Even if you could afford it at current prices (you'd need to remortgage), 64GB is the practical ceiling for flight sims.

Our Vanguard, Apex, and Titan tiers are excellent starting points. When you get in touch for a custom quote, mention "flight sim" and we'll adjust the spec accordingly — typically bumping RAM to 64GB and ensuring adequate NVMe storage.

Every build includes professional cable management, 48-hour stress testing, Windows setup, and a 2-year workmanship warranty. Local pickup from Salisbury QLD or Brisbane delivery available.

Frequently Asked Questions

What PC specs do I need for Microsoft Flight Simulator 2024?
At minimum: a 6-core CPU (Ryzen 5 9600X or Core Ultra 5 245K), 32GB DDR5 RAM, and an RTX 5060 with 8GB VRAM. For smooth 1440p with high detail, step up to an RTX 5070 Ti and a Ryzen 7 9800X3D or Core Ultra 7 265K.
Is 32GB RAM enough for flight simulators in 2026?
32GB is the practical starting point for MSFS 2024. The sim uses 20-24GB when streaming terrain. 64GB helps with add-ons, but DDR5 prices are steep in 2026 due to AI data centre demand. Start with 32GB and upgrade when prices normalise.
Does Microsoft Flight Simulator 2024 use more CPU or GPU?
Both, but differently. The CPU handles air traffic, weather simulation, and terrain streaming. The GPU handles rendering. MSFS 2024 is one of the few games where a strong CPU matters as much as the GPU. Prioritise single-thread performance (Ryzen 7 9800X3D is ideal).
How much does a flight sim PC cost in Australia?
A capable flight sim PC starts around $2,500-3,000 AUD for 1080p medium-high settings. For 1440p high with smooth frame rates, budget $4,500-5,500. A top-tier 4K setup with TrackIR and peripherals runs $7,000-9,000 AUD.
Is an NVMe SSD important for flight simulators?
Yes. MSFS 2024 streams terrain data constantly. A fast NVMe SSD (PCIe 4.0 minimum) dramatically reduces scenery pop-in and loading times. Budget for at least 2TB since the base install is 150GB+ and add-on scenery grows fast.
