So, I decided to try a mod. Jenka's nightmare. I was expecting this to run well, considering that my PC was able to run CS+ completely fine. That wasn't the case. It lags so much that it makes me want to scream. Not only that, but even the input refused to work at times. How can I fix this lag?
You might try the CS Mod Loader:
DLL mod loader for Freeware Cave Story (+ sample mods) - Clownacy/Cave-Story-Mod-Loader
github.com
Just unzip CS-Mod-Loader-v1.5.2.1.zip into JenkasNightmare
By default it should run in 60 FPS, so if you want to change that...
Go to JenkasNightmare\mods\graphics_enhancement
And open up settings.ini and change "60fps = true" to false and save.
There should be plenty of other ways to run Jenka's Nightmare and other mods, but that should work?
EDIT:
You could try using this instead for a more classic experience:
Fixed a deadlock when loading DDrawCompat on Windows 11 22H2
github.com
Don't forget to remove whatever file the zip has within before switching to another.
There also should be a way to play it multiplayer, or use that as an engine, though I haven't researched it yet; just noticed the videos~
