No worries. True 60p material is rare. However, 60i material is quite common, and after deinterlacing it becomes 60p. So if you have any music concert Blu-Rays, or maybe watch TV recordings or DVDs, then you might get 60i stuff, which will then be deinterlaced to 60p. With such material you'll probably get stuttering with Jinc AR with your GPU. FWIW, for *movie* TV recordings and DVDs you can use madVR's "film mode", which will then convert 60i to 24p (instead of 60p) which should then play fine again with Jinc AR. Music concerts, sports etc are troublesome, though.
