Confused by IR resolution

[aaouviz]

Hi hi,

So, I'm currently working on two PC's; one on windows 7, the other on windows 10. Both have max 2020 and Corona 5.

I've recently noticed a weird problem with my IR on the windows 10 PC (the IR is coming out blurry, or more precisely pixelated....but that's for another topic). When comparing IR on the two machines I'm dumbfounded why one does full-screen IR at 1329x997px, while the other does full-screen IR at 657x493px?

Both are running 1920x1080 resolution. The only tangible difference is that one PC uses dual 27" inch set-up (the windows 7, I've cropped out the second screen from the screengrab) while the windows 10 PC displays on a single 23inch monitor.

What's going on here? What am I missing? Please see two screengrabs for comparison

Hi,

This is to do with the Image upscaling factor feature that was added to help speed up the IR in high resolution. Currently it takes it's default setting from your Windows scaling settings.

It can be changed in Render Setup -> System -> Interactive rendering -> Image upscaling factor.

Thanks,

Rowan
