Frame Rate Trouble

Sometime before 0.36 or so I was getting around 65-90 fps on west coast usa in the vulkan render with the settings in the screenshot. Most recently I've been getting 48-62 fps. It's a little less with Gavril MD-Series. I tried adjusting some of the settings and now I can't even get to 30 fps in west coast usa even though it's at the same settings as in the screenshot now.
I tried in Safe Mode and it made no difference.

GPU: NVIDIA GeForce RTX 2070 SUPER
CPU: Intel Core i5-7500T 2.70GHz
RAM: 32 GB

 

Please post a screenshot of the fps monitor that opens with CTRL SHIFT F. It will say what's limiting you. Performance in other games is fine?

 

One the Utah map I get near 70-130 fps. In other games performance is fine as far as I know. How come I get 10 more fps if I rotate to camera to the front of the vehicle?

 

Probably because of the detailed mirrors. If you disable them, you should get the same performance in all camera positions

 

Detailed mirrors are already disabled

 

Are you using Vulkan or DirectX API?

 

Vulkan

 

Try using DirectX instead. Vulkan is known to lower the frame rate on many GPUs and stutters a lot.
