We will now (v.2018-09-16) gradually rolling out high-DPI support that some of you are asking for (by giving bad review). Here, I'd like to say that High-DPI support not a simple easy-peasy toggle of a switch (if it were, Adobe would have had high-DPI Photoshop early on). We do rely on others' UI framework. When such framework doesn't work as expected, we need to look for workaround. Not all software developers are as big as Adobe where you can have a whole arm of developers to work on it. So, please be more understanding and don't give the lowest review score in MS App Store simply because we don't have high-DPI support earlier. Without high-DPI, Expresii is still functional and gives you the world's most organic digital watercolor. Like some of the users say, Expresii deserves the credit. So, please leave a balanced review if you are to leave one.
Speed Impact
Using high-DPI rendering may not best suit your situation. If you're using a not-so-powerful GPU, you may notice slow-down after switching to high-DPI rendering. This is because previously the system is only using e.g. 1/4 of the screen resolution for artwork rendering and artwork rendering takes GPU times. With high-DPI support, we will use the full resolution of the screen and thus it'd take more time. You can see the rendering quality difference below (captured on my 2017 Surface Pro i7):
Blurry rendering using 1/4 the resolution (1/2 width & 1/2 height) and then scaled back up.
Sharp rendering using native screen resolution
FYI, my 2017 Surface Pro with Iris 640 dropped from 100+ to 60-80 FPS switching to high-DPI, depending on the zoom level. So, depending on your GPU, using high-DPI support may or may not be your better choice. FYI, we just got a user reporting that he's very happy with high-DPI on his Surface Studio that still gives 90-150 FPS after the switch.
You can always switch back
You can always switch back to System scaling instead of high-DPI via System Override. You right-click on Expresii's icon, and then choose Property>Compatibility>Settings>Change high DPI settings and choose 'System (Enhanced)':
You
Using 'System Enhanced', some of the UI text gets proper scaling. You can check out the rendering differences:
So, if you find painting is too slow, we recommend using 'System Enhanced' so that it's not slowed down and that you still get some of the texts scaled sharp.
The high-DPI support is not perfect yet. We'll keep working on it.
Update: We realized that the System Enhanced mode can not be applied to Store app! This is a limitation Microsoft set and seems they just don't care ☹️ (https://answers.microsoft.com/en-us/windows/forum/all/store-app-high-dpi-override/65ea15bb-2e48-4352-bf21-d6935e06a677)
