Hi, I'm an avid user of borderless windowed mode in all games where it's an option, because i spend a lot of time doing stuff on my secondary monitor. However, in trackmania the game becomes pretty much unplayable when using the borderless windowed mode. The FPS counter stays pretty much the same, but the game got massive stuttering, making it feel like it's running at 30 FPS.
In another game i play, Dota 2, the default setting is that the game sets the CPU to 30% priority when it's not the "focused" window. However theres a command called "dota_engine_no_focus_sleep" wich can change the setting to not lower the CPU priority when focusing another window, Does trackmania have something similar?
The fix i've gotten told, is to use fullscreen mode. While it works perfectly, my game often automatically just tabs out when i get notifications from some apps. (like microsoft team). The trackmania settings also keeps changing itself back to borderless windowed mode automatically, even if i have selected full screen.
The performance issue also seems to be changing from update to update. Sometimes it works fine, then later it's unplayable.
