Yes , Win32 / DirectX in common HAL for games now , just compile your game for windows/steam , you can run everywhere , minimize the headache of doing native game development , like breaking with X11 / wayland kde / wayland gnome / wayland mutter .

For the OSes runtime side you can depend on SteamOS / Apple's Game Porting Toolkit / Crossover / Proton / DWProton / Wine / and Android's Winlator/Gamehub/Gamenative .

For DirectX compatibility you can depends on Apple's D3DMetal , DXMT , VKD3D , DXVK and WineD3D .
