There’s a few settings that are performance killers. I can already feel you pouting so don’t fret. You aren’t the only one with a high end system brought to it’s knees by this game.
Some performance killing settings:
- AI (Duh…)
- Clouds (They’re still fluffy AF on High)
- Terrain and Texture LOD (100-150 looks no different than 250+)
- Terrain Precaching Radius (higher may lead to longer load times, lower may lead to performance hit)
- Online Features (Live Weather and Traffic)
- Photogrammetry textures (again…Duh)
- Your internet connection speed (your CPU is processing the data being streamed in as fast as the data is being streamed in. Like trying to drive a Ferrari in rush hour traffic)
There’s a great deal of guides out there that explain each of the settings how it impacts your game in better detail than i can.
imo, you’re a bit bottlenecked with your memory. 4 GB of overhead is not much especially if you’re running additional apps like Volanta/STKP/LNM, Navigraph, FS Realistic, web browser etc. Double what you got to 32GB and you should notice a boost. Make sure you get the exact same make, model and speed of your current modules. Get a 32gb kit and run in dual channel if you only have two DIMM Slots for that slight extra bump (your B450M is full size ATX, no?)
Best of luck
