Sapphire Nitro+ VEGA 64 - Cyberpunk 2077 - FPS same with Low and Ultra?!?

The game has very simple driving mechanics, only press throttle, turn and brake, but it is very fun with great sense of speed. The graphics performance of the game bothers me a bit still. I get same FPS with Low and Ultra settings, both at 49 FPS... I would have expected that low settings would give 70-80 FPS at least, but it gets 49 FPS. hopefully they will optimize the game in January, so that 60 FPS would be possible. Now it makes it makes no difference to the performance if I keep it on Low or Ultra, so Ultra it is. It looks like some people with RTX 3080 also have same FPS with Low and Ultra...
