Hey there @JWRHarding! Welcome to the community! So Dualshock and Dualsense controllers don’t have native support on windows. The reason steam games all work with them is usually because steam has a wrapper that takes the jumbled inputs and combines them into a normal Direct Input format. You should be able to get input from some of these controllers with the Raw Input plugin but not all of them, many developers end up using a wrapper themselves like Ds4windows.
