Dear Support, I recently switched from Win 7 to Win 10. I still use the same PC, except that Win 10 runs on a SSD, while Win 7 runs on a HD. I experienced that SC was struggling with Win 10 (higher CPU load, slower graphic scrolling), so I ran a series of tests comparatively on Win 7 and Win 10 with exact identical conditions for Sierra. My observations are : 1) Study calculation times are similar with Win 7 and Win 10. Some studies are repetitively faster, some are repetitively slower (within 20% deviation). 2) Chart drawing time is 2.5x faster with Win 7 than with Win 10. I have tried various stuff to solve the chart drawing problem of Win 10 (Sierra update, Nvidia drivers update, sierrachart_64.exe properties / "Compatibility" tab, Help #30 section...) , but it had zero effect. Apparently, this Win 7 vs Win 10 chart drawing problem is recurring for Sierra users : Win 10 performance noticably slower than win 7 Win 10 performance problem identified, with fix Sierrachart is very slow What I am asking here is additionnal help or new suggestions for getting the same chart drawing time with Win 10 and Win 7.
