Optimization modpack of Timeless and Classics Zero
This modpack provides a great TacZ experience and adds several useful features, so you'll not only experience an increase in FPS over the original TacZ mod, but you'll also be able to play the game more conveniently.
Difference from the original mod:
- Troubleshooting scope blockage (black square around scope)
- Great performance optimizations
- Added a few other useful mods
This modpack already includes a lot of addons, so you don't need to add anything else.
How to install OptimizedTacZ
With Millida Launcher
Install Millida Launcher
The launcher is free: download it at millida.net/launcher and sign in with any nickname.
Click “Install” on this page
The launcher opens and installs the modpack for Minecraft 1.20.1 on Fabric automatically.
Launch the game
A profile with it appears in the launcher: click “Play”.
Manually
Download the modpack archive
In the version list above, pick the file OptimizedTacZ 1.0.1.mrpack (140 MB).
Import it into a launcher
A launcher that supports modpacks (Millida Launcher, Prism) takes the archive via “Add modpack”, then “From file”. No need to unpack it yourself.
Allocate memory
Modpacks need more memory than the plain game: set 4–6 GB in the profile settings.
On a server
Use the “To server” button
On Millida Hosting, the button at the top of the page uploads the file to your server and restarts it for you.
Invite friends: they install the same modpack
To join the server, every player needs the same modpack version.
Minecraft 1.20.1 runs on Java 17: with a different Java version the game may close right after launch.
