He was running it at 1080p at a solid 60 FPS and mentions that the FPS counter went up to almost 80FPS in the driving sections so he clearly was aware of the actual FPS, i'm not sure what other youtubers have mentioned but that's something to bear in mind.
I'm also getting the 3090 (if I can get my hands on it in time for Cyberpunk) but I am just trying to temper expectations, if I can get a solid 60 4k with RTX enabled that would be great but also with the rumours out that these cards may run up to 70% increased performence for Ray tracing you might see it go much higher than 60 on 4k, we just have to wait and see - fingers crossed.
