TLDR - If I have a weak Win10 PC that is capable of direct playing a media collection, is it safe to assume that I can also install PMS on that PC and then use the desktop app (on the same PC) to successfully play the media?
Longer version - We own a small property that is located somewhere that has only phone hotspot internet access, so using my main home Plex server remotely for that location is not possible. I have an old htpc that has a weak 4th gen i3 Intel processor (4gb ram???), but it has an nvidia gpu that can play the 1080p hevc media that I have on an external hard drive. I am able to play the media fine through Kodi, but I must say I don’t like the Kodi interface as the customization of the home page and libraries is lacking compared to what I can do with Plex. If I will not be transcoding audio or video, is it silly to think I could install PMS on that PC and play the media through the desktop app without internet access? Or might PMS have a significant hit on performance when running both? I can just install both and try.
