Im recently struggling with the serious random stutters in rfactors for almost one month, i almost tried every possible means in every corner of bios/windows system/steamvr/wmr,
and finally the solution is to reinstall the windows11 and avoid install any latest update package.
A fresh install of steam and steamvr
A fresh install of rfactor2
Make sure everything is fresh and don't touch the default setting unless you have to.
Now my rfactor2 is almost butter smooth
But i admit rfactor2 vr is a very vulnarable system, any driver/software update may ruin the performance
My rig is 3090+14700k+32g+g2, pretty close to your setup, i don't think you will have any issue running rfactor2 vr at high graphic, mine with 16 visible cars, msaax4,fxaa on, high circuit/opponent/shadow,ultra raindrop, road reflection off, amost stable 90fps in all time all weather, very ocasion stutter.
