RE: choppy playback with newer cards and drivers and using FSE as workaround. I've noticed that some settings in madVR only apply when using windowed and therefor use more resources. When changed to FSE, the resources are not used and the settings are not applied afaik. I noticed this during playback when I switched from FSE into windowed by double clicking the player window field and the title would start to stutter. I created the ShowRenderSteps folder and noticed when windowed, many processes were present in madVR OSD. When I double clicked the player field and it goes back to FSE, those processes no longer showed and playback resources relaxed.
