Hi. I have an issue I had with Quake Live recently, I don't know how I solved it with Quake Live, I don't remember. Now I have the same issue with Quake 3. The screen contains only part of the image, everything else is beyond the viewport. I have 125% DPI settings (fonts scale settings), because my screen has higher DPI and I need to be able to read the texts I have on screen. My resolution is Full HD (1920x1080), but DPI is about 90, screen size is like 17", smaller than a normal Full HD monitor. Setting 100% fonts scale would make my eyes hurt. Yes, I know I can set up Chrome page to 125%, but I need this settings system-wide, and only way to achieve this is by setting it up in Windows. That, unfortunately, tries to scale up older apps, including games, so the settings I am using in current build of Windows 10 makes Quake 3 and Quake Live screen appear to be larger than the screen itself.
I tried to set some settings, but now even after I reset the compatibility settings, I cannot launch the game. It shows the console, no error appears, it actually launches afterwards, but suddenly shuts down, without any error noticed. Console does not appear again informing about some error. What's up?
Quake 3 does not work on higher DPI settings
Re: Quake 3 does not work on higher DPI settings
So Quake Live works with settings to override higher resolution DPI settings by app. However, it doesn't with Quake 3
