Scaler 2.1.2 seems improved a lot

it seems the latest release fixed my RAM issues: Scaler 2.1.2 sucks about 1/10 (or less) compared to the previous amount, and seems stable

after having reconstructed the story of my first purchase & upgrades and crashes, I think that, at least in my system, the not working Scaler was possibly the 2.1.0 and surely the 2.1.1 release
