If all other "enhancements"(intel graphics driver & nvidia graphics driver have some of them turned on by default) are turned off then there should be zero difference between image quality between intel & nvidia decoding. UHD770 is technically much faster than UHD730 I think but that's like saying hero bicycle is faster than atlas bicycle as both of them will be blown away in speed by any car(aka dedicated graphics card like 1050/equivalent).Is there a difference in image quality between Intel's decoding and Nvidia's?
And does the difference between UHD 730 and UHD 770 matter?
