I've been playing this game since day one and have tested multiple tracks with persistent issues. This issues have been verified by other members on the EA WRC reddit community.
There are a number of advanced graphical options that are tanking the games performance:
- Shadows
- Reflections
- Mirrors
- Crowd
- Ground Cover
- Trees
Some of the more poorly optimized courses can drop the fps by over 60fps with just a single setting of ground cover between Ultra 60fps to Low 176fps.
Ravin de Coste Belle has some very repeatable issues midway down the course.
These optimization issues are mostly CPU related and deeply effect the gameplay on flat screen and VR.
System - 4090, 12900k, 64 gigs ddr4, Fast NVME
Settings are 4k DLSS4 - high to ultra settings, no mirrors, low crowd, ultra low reflections
