Quick Answer
Yes. The RTX 5090 runs Forza Motorsport at 4K on Ultra with ray-traced reflections at roughly 100-130 fps, depending on grid size and weather. With DLSS Quality it clears 140 fps, making it an excellent match for a 4K 144Hz panel and a wheel setup.
Ray tracing and full grids are the workload
Forza Motorsport's track-side ray tracing and 24-car grids are heavier than Horizon's open world, so at 4K Ultra the 5090 lands around 100-130 fps. Wet-weather races at Spa or Le Mans with full reflections sit at the lower end, while dry sprints push higher. DLSS Quality is a sensible default to keep frames above your panel's refresh without softening the cockpit detail.
Pair it with the right CPU and display
Race-start physics with 24 cars lean on the CPU, so a Ryzen 7 9800X3D keeps the 1% lows steady when the field bunches into turn one. A 4K 144Hz panel is the target display, ranging from roughly R14,000 to R35,000 at Evetech. With a wheel and pedal set, this combination delivers a genuinely simulator-grade experience at native 4K. For the cleanest race starts, lower the crowd density one notch if you run a full 24-car grid in the wet, since that single setting recovers the most frames during the heaviest turn-one moments.
FAQ
What FPS does the 5090 get in Forza Motorsport at 4K?
About 100-130 fps at Ultra with ray tracing, varying with grid size and weather. DLSS Quality lifts that past 140 fps for a 4K 144Hz panel.
Is ray tracing worth enabling in Forza Motorsport?
Yes on a 5090. The reflective track surfaces and car bodies look noticeably better, and the card has the frames to spare, especially with DLSS Quality on.
Does grid size affect frame rate?
Yes. A full 24-car race start is the heaviest moment and drops frames into the low 100s at 4K. Practice and time-trial sessions run considerably higher.
Build a 4K sim-racing rig
Pair the 5090 with a 4K 144Hz panel and a 9800X3D for steady race starts. Compare monitors and CPUs stocked at Evetech to complete the setup.
