Previously, yuzu would try and guess which vsync mode to use given
different scenarios, but apparently we didn't always get it right. This
exposes the separate modes in a drop-down the user can select.
If a mode isn't available in Vulkan, it defaults to FIFO.
On Windows, a borderless window will be treated the same as exclusive fullscreen
when the window geometry matches the physical dimensions of the screen.
However, with High DPI scaling, when the devicePixelRatioF() is > 1, the borderless
window apparently is not treated as exclusive fullscreen and functions correctly.
One can verify and replicate this behavior by using a high resolution (4K) display,
and switching between 100% and 200% scaling in Windows' display settings.
At 100%, without the addition of 1, it is treated as exclusive fullscreen.
At 200%, with or without the addition of 1, it is treated as borderless windowed.
Therefore, we can use (read: abuse) this difference in behavior to fix this issue for
those with higher resolution displays when the Qt scaling ratio is > 1.
Should this behavior be changed in the future, please revisit this workaround.
- Added IPv6 & Namespace support in direct connection Regex
- Updated Tooltip for Direct Connect UI
- Removed Dropdown Connection Type in Direct Connect
devicePixelRatioF() returns the scaling ratio when high dpi scaling is enabled.
When high dpi scaling is enabled, the raw screen coordinate system is scaled to device independent coordinates.
This uses Qt's new high DPI application attributes for scaling the current window.
However, these aren't perfect as scaling with non integer scales will cause artifacts in UI, icons and other elements.
Therefore, we use a heuristic to select an appropriate integer scale value depending on the current screen resolution and applies this to the application.
