Thank you for playing! Looking at the video it seems like models didn't load correctly, either being very warped or completely flat (like the lamps), I'd recommend to wipe clean your config, update Gzdoom and also the video card drivers, if you keep seeing the issue try switching from OpenGL to Vulkan or do the opposite if you use Vulkan by default
Kind of too late to be doing any of that considering the game is no longer on my box after creating this video Lol. Used whatever the default settings were apart from resolution which I set to 1920x1080 for recording purposes. GPU drivers are up to date so that is no issue. Had the most up to date version of gzdoom seeing this was my first time ever interacting with it/first time downloaded. Would put in the description here about configs. I ran the game as is after downloading everything. I do see in other people's videos that the objects are perfect, so I wonder if gzdoom automatically does the settings. I thought the reason the objects were like that because of engine limitations. Still was a great experience and awesome recreation for what it is.
