Mio, don't know if this might help you out or not.
I have a win10 machine I built late in 2019 for gaming. I just ran all 75 videos on it with hardly any problem, using both Nox and Bluestacks.
All 3 say I can download an update, but none are requiring me to.
Win10 is on ver. 10.0.19046 build 19043 says I could update to 21H2
Nox is running 126.96.36.199 shows I could update to v188.8.131.52
Bluestacks is running 184.108.40.2066 N32 shows I could update to 220.127.116.110
All is working well, so see no need to update anything.
I needed to run to 4388 credits to get the 150 Blue stopped at 4316, tried first just staying on blue and restarting vids, that didn't work, next shutdown wgt and restarted vids, that also did not work. Shutdown Blue restarted and vids continued. Nox during this whole time continued to run vids.
This machine in question is running a Z390 MB, with a I5 8400 cpu running on a SSD, I have not messed with cpu cores or anything else.
Most of the time both Nox and Blue will continue to run all videos.
I normally don't use that machine for wgt, I use the win7 machine I am typing on, but found both Nox and Blue had problems consistently running on 7 correctly. IIRC the highest version of Blue that would run on 7 was 4.
I don't run these on the multi, I run on the single instance.
