You have some memory leak issues with firefox.exe and explorer.exe. I don’t think I’ve ever seen an explorer.exe radarpreleak before. Radar stands for “resource exhaustion detection and resolution” (yeah, I know, kind of dumb that the A in exhaustion is used, instead of E lol…) and is usually a sign of some kind of memory leak, but not always. Like some apps might actually use a boatload of resources, if say you’re working on some big open world realistic style game in Unreal Editor.
But if apps like the explorer are running into resource limits, it means that either something is hogging all the ram and the explorer just happened to be the straw that broke the camel’s back, or that there’s something else going wrong with your system. Are you one of those people that keeps 10000 tabs open in a browser? Maybe try closing out of all of them and retest with just WoW and a single browser tab.
Also, a couple other things:
- disable hardware acceleration in firefox and see if that helps
- make sure that your gsync settings are set to fullscreen only and not fullscreen+windowed. wow uses borderless windowed fullscreen, which counts as fullscreen to gsync(I think so long as MPO and FSO aren’t disabled).
