Unfortunately the framework used for the game, LOVE2D, currently does not support the ability to enable application DPI scaling from within the game. You’ll have to do that manually, however it’s really just 3 clicks in total.
1. Right-click on the game’s executable (intravenous.exe or intravenous_demo.exe) and click on ‘Properties’.
2. In the window that opens, switch over to the ‘Compatibility’ tab.
3. Click on the ‘Change high DPI settings’.
4. In the window that pops up after that, tick the “Override high DPI scaling behavior. Scaling performed by: Application” checkbox.
Apply the changes, and done, you should be good now!
This is only a necessary step if you have window scaling set to above or below 100% in the Windows display settings. If it’s at 100%, then you don’t have to do this at all!
With that said, the other way of taking care of the issue is to set window scaling to 100%, however I can imagine this is more annoying than just changing the DPI settings on the game executable itself.
