VR simulation is where “pretty good gaming PCs” get exposed fast.
Not because they can’t run VR… but because VR punishes frame-time spikes. One tiny hitch becomes a nausea button. The goal isn’t just high FPS. It’s smoothness you can trust—especially in sim-style VR where you’re moving your head constantly.
Below are three Sirius builds that cover the full ladder for the best gaming PC for VR simulation:
Half-Life: Alyx
Minimum on Steam: 12GB RAM and GTX 1060 / RX 580 (6GB VRAM). It’s still a go-to VR performance test because it exposes stutter instantly.
VTOL VR
Steam lists 8GB RAM minimum / 16GB recommended and a GTX 970-class GPU. It’s lighter than flight sims, but it still rewards smooth frame pacing.
iRacing (VR)
iRacing’s own requirements list 16GB minimum/recommended and 32+GB for High End—which matches real sim rigs (telemetry apps, overlays, Discord, browsers, etc.).
Microsoft Flight Simulator 2024 (VR)
MSFS is a heavyweight even outside VR. It’s common for flight sim builds to target 32GB RAM as a practical baseline, especially when you stack scenery streaming, airports, and add-ons.
(From a Buyer’s View)
VR is different from normal gaming because your headset is basically asking your PC to do this, all the time:
So you’re buying for:
VR + sim rigs stack devices fast:
VR libraries grow fast. Big sims + VR titles + updates = you’ll appreciate 2TB quickly.
When VR feels rough, don’t just nuke everything. Do this order:
If you can’t hold your headset refresh target consistently, drop settings. Smoothness wins.
Expect MSFS to benefit from more system headroom than most VR titles (it’s heavy even before VR).
