Poor game performance - AMD Radeon RX 7900 XT

Good morning,
I've been experiencing low FPS in BeamNG drive on my high-end system after upgrading my GPU. Maps like Utah and the new desert map run around 60 FPS with traffic spawned in. Maps like Italy or West Coast USA run at or below 50 FPS with traffic. Issues started happening when I upgraded to an AMD Radeon 7900XT from an RTX 3080. I had higher frame rates with the Nvidia card. I tried other games and they all play at higher framer rates than the 3080. I don't have any mods installed so that shouldn't be the issue. I did notice the GPU usage was around 60%. I feel this game is not utilizing my new GPU properly. Reinstalling the game and clearing the cache made no difference.

Also, I recently upgraded the ram since I was getting a message from BeamNG that my system was running out of ram. Didn't make a difference and the FPS was unchanged. Checked the task manager and BeamNG was not utilizing the extra 16GB of ram with traffic spawned in.

Also, is there a way to minimize the jagged edges in this game other than using supper resolution?
