Just curious, what type of Videocard are you using?
Looking at the video data at the top of those screenshots shows Max video memory used is around 580+ MBs but on the video memory available side, it is only showing 69.6?
That don't look right...... Is your PC an INTEL with possibly a i5=****K or i7 or i9 K CPU (the INTELs with a K at the end have onboard graphics built into them) ....just wondering if your PC has switched your GPU.... Maybe because of a Windows 10 update or something....
