No, if it were me I would stick with the video card and just use opengl video rendering. You would be the one to tell me whether you configured with the --enable-opengl-video flag. If you didn't, then yes, you will need to recompile with it. Playback profiles are located in Utilities/Setup->Setup->TV Settings->Playback and are on the third page. They are essentially "rules" for various resolutions that set deinterlacers and renderers. So, I have no idea what the default ones are, but find the one that encloses 1920x1088 resolution (probably the last one on the page, something like >1280 720 or >1280 720 and <= 1920x1088 or something like that. Hit the edit button for that rule. For maximum speed, I would remove all deinterlacers (Primary and Fallback deinterlacers to "none") and set video-renderer to opengl.<div>
