Prboom – Working rewind and WIP Runahead support!

Prboom, the Doom 1/2 game engine core, has finally gained serialization support. In this video, you can see rewind being used, as well as experimental runahead support!

Runahead support is currently incomplete and you can see some of the status bar elements flashing, some of the screen updates also are improperly rendered right now. The promise with runahead though is that we can start shaving off large amounts of built-in game latency once it’s working perfectly! For the best results right now with runahead, we currently recommend that you enable ‘Use second instance’ and set ‘Runahead Frames’ to 1.

Start up your copy of #RetroArch and upgrade your core to the latest version of Prboom to enjoy these latest new features!
