They’re probably assuming it’ll be here on Tuesday because the Pop-Up PTR has ended, and the thread has unceremoneously been unpinned, indicating that they have a fix and are likely going to deploy it this week as the PTR ended back on 8/16.
With any luck those assumptions are correct. Windows users have been having to deal with a lot of issues with D3 over the last year and a half. I’m also hoping that this has a fix for the problem that affects both Windows and macOS wherein D3 will randomly suffer an issue where the inventory icons take ages to load if you are anywhere other than in town in the Act 2 zone. The workaround for that is to change texture resolution between High <–> Low and back again (so if you are on High as most players are these days, you set it to Low, click the Apply button, then set it back to High agan and click Apply again). This bug affects macOS more frequently than Windows, likely due to macOS’ more recent versions having barely functional OpenGL drivers as that is what D3 uses on that platform vs. DirectX 11 on Windows.
