It was an asshole thing to say. He could have still have provided the opinion without calling it "mobile". Even if he redoes the video, the damage is already done. At the least he could say is "sorry". But in this day & age it's OK to be an asshole. :/

While this is beating a dead horse to death, however certain aspects of D5 looked like mobile rendering IMHO, from various online footage. I believe the bigger issue is, relying upon online footage as the only source material, and lacking the proper hardware tools internally on presenting such opinions and observations. Hopefully as his channel and viewership grows, he'll be able to provide more accurate and neutral observations with the correct tools in place.
