This topic is NOT meant to discuss the preview quality in general.
From PL8 docs on ‘Edit->Preferences->Display->Preview quality’ setting:
Always prefer high-quality previews: If you check this option,
the image display in the Viewer of the Customize tab
will always be of very high quality,
which may have an impact on the responsiveness of DxO PhotoLab.
Has anyone seen the difference in quality or processing time (in ‘Viewer’ or ‘Full screen viewer’)?
To be honest, I didn’t “study” the topic, but quick tries didn’t show any significant differences. Maybe I wasn’t careful enough or my glass is too good.
PL8 measurements for my PC found in PhotoLab log:
cpu perf : 79.0582 (i7-14700KF)
PerfIndex = 564.966 (RTX4070-566.36)
EDIT: My monitor: EIZO CS2740 in sRGB mode, 3840x2160 at 175% text scaling mode.
OS is Win11pro, currently 24H2 + latest patches.
Had set DPL for high quality display for a while, but switched it off again due to an impression of slight lags and because I’m not obsessed by getting the veryveryverybest at anytime and everywhere.
I didn’t “feel” any difference (but didn’t measure it).
Neither am I. Just checking if I’m not missing something elementary about the setting.
About a year ago I did a quick test with PL7.1 (my first PL version) and decided to switch it OFF. Around a month ago I have switched it ON in PL8 for the sake of some forum topic and forgot to reset it back. My highly “unscientific” conclusion was that there is no practical difference, since the setting did not seem to have any impact on my editing decisions. However, since I mostly shoot at “insane” ISO, and use the Loupe anyway, the setting is probably unimportant to me. But for photos which require some thought and may take an hour or more to edit “correctly”, it might be different. So, maybe I’m missing something, because of my “instinctive” way of editing? Just checking.
I’ve also set the preview to “High quality” but can’t tell for sure if I get a performance lag from it (still using NVidia 1060 6GB). With PL8’s new zoom tool I get some delay before the image appears clear.
Screen is an Eizo CG2730 / 2560x1440 / still running on Win 10 / 125%.
There’s an awful lot of misunderstanding about what this option actually does. It only affects the quality of the image preview while dragging an adjustment slider. That’s all! With high-quality previews on, the image will not blur while making the adjustment by dragging a slider. With hq previews off, the image will blur.
Yes, some of us are more familiar with how it works than others, either due to beta testing it (PhotoLab 5?) or due to later interactions with DxO. I can’t explain why the user guide is so cryptic about it.
Same here. Whether pixels are shifted or brightened a bit doesn’t usually change the image subject/story…
Moreover, most users probably don’t work under controlled conditions and differences (unless they are obvious) will be mostly veiled by changing conditions.
Thanks to all for the responses.
Maybe @Pieloe work is what made me set the option OFF while on PL7.1 trial. Looks like I have to go back to school and re-read https://tutodxo.com
