FPS game engine GZDoom 4.5.0 is out as the first 64bit only release

GZDoom, the modder-friendly OpenGL and Vulkan source port based on the DOOM engine has a major new release up as they drop support for 32bit.

A number of major changes were pulled in for GZDoom 4.5.0, which will likely affect most users. For starters, mouse behaviour has changed. They've removed some "magic factors" from the mouse sensitivity and while old configurations will get moved over it might still need you to do some settings tweaks.

Some of the highlights of GZDoom 4.5.0 include:

• For all of Doom's fullscreen images there's now widescreen versions provided. The other games are still being worked on and will be added later when they become available. All new images were created by Nash Muhandes - this does not use any of the versions from the Unity port.
• A simplified options menu is now available for quick setup of the important settings.
• New keybindings presets. Users can now choose between the classic layout and a WASD-based one
• Menu and intermission screen now scale to the original Doom.exe's layout by default.
• Major additions to the menu system - animated menu transitions, image slideshows and fixed size menus can now be created.
• Various enhancements and fixes for ZScript.
• Interpolate positions and angles in the automap for smoother appearance
• Optimization of the patch texture checker
• MIDS-format MIDI support
• OPUS support, courtesy of an updated libsndfile.
