Alright, I've had to uninstall ESO because I has a conflict with either BOINC or one of the projects I'm signed up with in BOINC, all of which I turn off while playing but still glitches out when ESO is installed. I know it's BOINC since the two mutually glitch when ESO is installed forcing a reinstall of the former, and a complete uninstall of the latter, because when I try to login, I get through the splash screens to the login page and the game just freezes while nothing else is affected unless I forget to turn off BOINC (which results in severe but unsurprising slowdown due to the nature of BOINC) Whereas BOINC will sometimes just run completely unresponsively with ESO installed with a repair via the BOINC installer the only way to fix it. Given a choice, I'll stop playing ESO, and just let BOINC run.
If it helps, these are the BOINC projects I run: Collatz Conjecture, GPUGrid, PrimeGrid, Pogs, Universe@Home, ClimatePrediction.net, SETI@Home, and WUProp@Home. All drivers and such are up to date as well and I have more than enough horsepower with a Skylake i7, a GTX 1080, and 16 GB of RAM. Admittedly, this is a rather obscure collision but, still. If I can get it fixed...
