• Optimizations have been made to further improve the overall performance and stability of DOOM Retro, particularly in the handling of large numbers of blood splats.
• DOOM Retro’s splash screen has been redesigned.
• Minor changes have been made to text that is output to the console.
• The CVARs in doomretro.cfg will no longer be reset if DOOM Retro quits with an error during startup in some rare instances.

• The last WAD to be opened now prepopulates the File name field in DOOM Retro’s WAD launcher.
• The r_shakescreen CVAR has been renamed to r_shake_damage and is now 50% by default.
• The screen will now shake when the player is near enough to an exploding barrel. This feature may be disabled using the new r_shake_barrels CVAR.
• The following changes have been made to the vid_showfps CVAR:
  • When both the vid_showfps and vid_vsync CVARs are on, the frames per second displayed will be red if less than the display’s refresh rate.
  • If the frames per second drops too low, a warning will now be displayed in the console.
  • If the CVAR is disabled in the console, the minimum and maximum FPS since the CVAR was enabled will now be displayed.
• An exec CCMD has been implemented that allows a series of commands stored in a file to be executed at once as if they had been typed in the console individually.
