Hi guys,
I think it's a little strange to default the IR scaling factor to 2.0. Many of us are using HighDPI monitors so I get that IR is slower at 1.0, but 1.0 is essential for this otherwise IR is extremely blurry and images are saved at a different size than expected from the IR window. I would suggest to default it to 1.0 and then have users manually change it to 2.0 if they are finding IR to be too slow on HighDPI monitors.
Also, upgrading from v6 RC > v6 proper appears to reset whatever value you have back to 2.0.
Cheers,
