ryzen7 5950x 128 GB RAM +
3090 24 GB = 115-130 FPS with DLSS (W/O: 80-95 ) resizeable
BAR ON
ALL EPIC no motion blur, no VSYNC, 24 cars visible, LOD medium
Pro: Smooth gameplay no horizontal jumps, enough details for very clear view,
Contra: expensive setup for use that for ACC only
My opinion: Shadows makes a big different, MIrror distance too.
