Calculators
Hardware and bottlenecks
- GPU vs VR Headset BottleneckCompare a GPU performance score and VRAM with a headset’s minimum score, resolution and refresh. Sixteen catalog pairs include a written verdict.
- Wheelbase and Wheel Quick ReleaseSee whether two sim-racing quick releases bolt together, need a first-party hub, a third-party adapter, or should not be mixed.
- Pedal Load Cell Rig StiffnessTurn brake force in kilograms and pedal height into newtons, a moment at the deck, and a 4040, 4080, 40120 or 40160 suggestion.
- USB Hub Power for a Sim RigAdd the USB draw of rig peripherals. Above 4.5 W the hub should be powered, and the suggested budget is 1.5 times the sum.
Displays and field of view
- Triple Screen FOV and AngleScreen diagonal, aspect and eye distance give the width, the single-screen FOV, the side-monitor fold angle and the total triple FOV.
- Ultrawide vs Triple ScreenCompare one ultrawide with three 16:9 panels on width, horizontal pixels and field of view at the same eye distance.
- VR Pixels per DegreeDivide horizontal and vertical pixels by the headset field of view. A named preset replaces the four fields. 60 PPD is the 20/20 reference.
Rig building
- Aluminium Extrusion Cut ListA 180 cm reference cockpit scaled to rider height, rounded to 10 mm: base rails, crossmembers, uprights and pedal rails, plus the total length.
- Direct Drive Torque and Rig StrainWheel torque and rim diameter give the force at the rim and a 4040, 4080, 40120 or 40160 profile suggestion.
- Sim Seating PositionRider height and a GT3, F1 or rally preset give seat-back angle, pedal drop, wheel reach and a leg length to the pedals.
