4K Resolution Problem

Postby canerpense » Mon Jan 08, 2018 11:17 am

Hi all,

This is my first message here, i decided to give my "problem" a shot when I saw that the helpful and kind community of this forum. I recently grabbed a 65" 4K TV (at a steal price) and tried gaming on it. A 3GB GTX1060 struggles with most 2017 AAA titles on highest settings but that is not an issue with FG, it runs really smooth so far.

The first issue I'm facing is that there is no in-game setting to scale the UI (that I could find). In-game menus and letters become so small that it is impossible to read them. The splash/welcome screen looks kind of fine at 4K resolution although could be a bit larger or resize-able.

Second issue is that enabling or disabling full screen option sometimes messes up the Windows's resolution setting, forcing screen to jump between 1080p and 2160p resolutions, making it flash and go blank while constantly changing resolution. ALT+F4'ing and changing settings in the splash screen solves this problem.

I'm at work now but I'll provide SS or video when I get back home.

Hi,

Welcome to the forum, and congratulations on having such a large screen! I'm delighted that FG is running so smoothly.

Unfortunately there's no easy way to scale the UI. However, there is a second UI "style" that you can enable which is slightly larger and may be more legible. From memory if you look at the Debug menu there's a toggle-UI option to switch between them.

For the sake of completeness, there's the external browser-based Phi GUI created and maintained by Torsten (see the wiki for details).

Other than that, there's a dedicated Qt5 UI in the process of being developed, and its developer has repeatedly stated that he's "getting really close to having the PUI replacement UI suitable for beta-testing", even actively discouraging any work on overlapping efforts in the PUI/Canvas department in light of the recent progress: http://wiki.flightgear.org/PUI

Your best bet would be getting in touch with the devel list to see if you can help with any of the "beta testing".

Besides, if you don't mind tinkering/coding a bit: for the built-in UI there's an experimental parser written in Nasal (fgdata-only) that processes a subset of the existing PUI/XML markup that is then dynamically mapped to Canvas primitives - which is to say, that it would be possible to use this approach to scale everything as required, as long as it's primarily dealing with osgText nodes and vector graphics obviously:

Thank you :) I found it under the debug menu and i think it was "cycle UI". UI gets a bit larger and easier to read but still pretty far from what would be suitable for use.

I downloaded HD scenery and getting 30 to 60 FPS with ALS shader with everything else maxed out. Memory consumption is around 1700MB, with the other Rembrant shader, albeit worser light effects, FPS drops and memory use increases.

Will try the external UI on my phone, but I'm not sure it will work as intended. Being a newbie here, how do I contact the QT5 UI developer?

see the links at the very top of this page? above the graphic? click on the mailing lists one and sign up for the developers' list... posts come at you as emails or you can choose to have a daily digest emailed to you... all the real serious work and discussions take place on the mailing list...
