-Fabric + Optifine: Optifine does not work
-Forge + Optifine: Replay Mod does not work
-Account in single player "Cloning": Has not worked since the end of 2020 either
Is there any option where it is enough to have an account and a PC?
-Fabric + Optifine: Optifine does not work
Then install OptiFabric.
DO I HAVE. Did not work. Has crashed all the time. Is not supported.
Is there an error message? If yes, which?
Here you have a timelapse mod:
https://www.replaymod.com/
I used that. Crash with Optifine + Optifabric
You then have to use a lighter shader: I recommend using the BSL shader
and first start Minecraft with the shader and then add the Replay Mod and restart Minecraft.
(Minecraft is overloaded by the sudden high CPU performance, which is why you have to load everything individually)
