Unfortunately I´ve not heard any solution for this.
Now I tested a little with my hardware possibilities and found that my old desktop (IntelCore2 Quad 9550, 4 GB DDR2!-Ram and AMD RX 570) isn´t running so bad - the loadingtimes are terrible, but if the H-scene is loaded it´s running with sufficient 35-40 FPS.
For comparison my Gaming Laptop (i7 9750H, 16GB DDR4 Ram and Geforce GTX 1660) isn´t that much better with 50 - 55 FPS, but still fast against what I´ve heard from RTX 3xxx cards.
For the comparison I used a "heavy" card from Sykosis with a lot of shaders (98 MB)

Therefore I assume that AMD cards handle the games graphic engine better than NVIDIA cards.
Maybe it is a Nvidia driver issue, I can only recommend to use the newest driver for your card.
