I posted a similar problem here:
On my laptop it take SGP over twice as long to download and save a file as Maxim DL and even longer compared to Sharpcap using the ASCOM camera driver.
On my i7-4790 desktop these delays disappear - making me fear that for most people with fast computers they don’t see this problem. I hope it will be addressed as many of us use slower machines to save power when in the field.
