• Frame generation (new). Between two pictures a game draws, ProsperoEden can show one made up from them, so a 30 FPS game looks like 60. It is in Settings > Video and in each game's own settings, works with the Vulkan renderer, and needs your own copy of Lossless Scaling: without its Lossless.dll the settings are greyed out. See Frame generation. Contributed by gyn7561.
• A new loading screen. It lists the steps of a game's start (reading the game, starting graphics, building shaders, starting the game) with a progress bar; while shaders are built it counts them. A step that lasts gets its seconds shown, so a start that is stuck can be told from one that is slow.
• Cheats in a file of their own work. A cheat file placed straight in a game's mods folder (cheat_<name>.txt) was listed and switched on, but changed nothing in the game. It does now. The session log also names the game's build ID, the name a cheat file for that version of the game has.
• A game no longer fails every start after a crash. A crash, or a console that went down, could leave a game's shader cache file damaged; that game then crashed at every start on the same renderer. The damaged part is now cut off and the rest is kept.
• No more stutter from log writes. Games dropped frames every few seconds while the logs were written. Logs are now written in the background once a second; Settings > Diagnostics > Write logs at once brings the old behaviour back, to find a crash. Contributed by matschi95.
• The FPS overlay with frame generation. It shows the game's own rate (N) beside the rate on screen (F) while frames are being added, and its usual single figure otherwise. Contributed by gyn7561.
• The log says why frame generation is not running, in lines that start with framegen:. Contributed by gyn7561.
• A Nix shell for building. shell.nix sets up the whole build environment. Contributed by Bauls Deep.
• Issues are open on GitHub, with forms for bug reports and game reports; they ask for the save data and the debug logs. See Issues and reports.
