TecniLauncher allocates RAM to Minecraft on a per-profile basis. Each profile has its own memory setting so you can give more RAM to heavy modpacks and less to lightweight setups. Java is managed automatically — you do not need to install Java separately.

​
Setting RAM for a profile

When creating or editing a profile, use the RAM slider to set the allocation. The value is stored internally in the profile’s MemoriaRam field as megabytes (for example, 4 GB = 4096 MB). Each profile displays its allocation in the launcher — for example: Fabric 0.15.11 • 4 GB RAM.
Events may have a minimum RAM requirement. The launcher enforces this minimum — your allocation cannot go below the event’s required amount.
SetupRecommended RAM
Vanilla (no mods)2 GB
Small modpack (< 30 mods)4 GB
Large modpack (> 100 mods)6–8 GB
Heavy event/modpack8–16 GB (check event minimum)
Do not over-allocate RAM. Leaving at least 2–3 GB free for Windows and other applications avoids lag. For most setups, 4–6 GB is the sweet spot.
Allocating more RAM than your system has available will cause crashes. Check your total system RAM in Windows Settings before setting values above 8 GB.

​
Performance mode

Each profile has a Performance mode toggle. When enabled, TecniLauncher applies additional JVM launch flags — primarily garbage collection tuning — to improve Minecraft’s runtime performance. This is useful for modpacks that experience frequent stuttering or frame drops.

​
Java management

TecniLauncher uses CmlLib.Core to manage the Java runtime. The correct Java version is downloaded and used automatically based on the Minecraft version you are launching. You do not need to install Java manually or configure JAVA_HOME.
