• 4GB patch the .exe, so that it can use max 4GB RAM instead of 2GB ntcore if you have more than 2GB RAM.

• DXVK DirectX to Vulkan translation layer. Download DLL from GitHub -> Releases and drop it into "PAYDAY 2" folder. Steam Community Guide with some explanation (Ctrl + F, type "dxvk" without quotes).

Also using HoloUI for the HUD + to replace a bunch of screens with generally-better-performing versions, e.g. blank main menu, blacked-out in-between-menus non-level loading screen, etc. Also possible to use a different HUD and accomplish - at least most of - this with more mods that can be found on MWS, of course.
