IEH2 [ver. 3.1.2.1] Massive Optimization!

Idle Mode (Performance Optimization)

• The game will enter Idle Mode after 30 seconds of no player input.

• Idle Mode is applied only to normal areas and dungeons.

• Super Dungeons and Challenges are excluded and will continue to run normally.

• Idle Mode is applied only when the area clear time is less than 1 second in real-time.

• Areas that take 1 second or longer to clear will continue to run standard battle updates as usual.

• Idle Mode is also applied during Auto World Ascension and Auto Rebirth.

How Idle Mode Works

• In Idle Mode, Battles for Passive Heroes are fully calculated through simulation rather than running the standard Battle Update loop.

• This significantly reduces CPU load.

• For example, when all 6 Heroes are set to Active/Passive:

  • The 5 Passive Heroes will switch to simulation-based Battle processing.

  • As a result, the Battle processing load is theoretically reduced to approximately 1/6.

• Overall, this results in up to around a 50% reduction in total CPU usage for the game.

• While in Idle Mode, EXP, Gold, Resources, Materials, Equipment, Capture #, Defeat #, Skill Trigger #, Area Clear Count, etc will continue to be gained normally.

Background Mode Improvements

• In Background Mode, not only Passive Heroes but also the Active Hero will be fully simulated.

• This results in a dramatic improvement in overall game performance while running in the background.

Others

• Added: "Common Talisman Gain from Swarms + X%" at Town [Cartographer] Lv Milestone Lv90-100 and AMM5250, 6250, 7250.

• Added: Talisman [Nari Sune Doll] extra passive effect "Talisman Fragment Gain +%"

• Added: A new option "Disable Auto SD during Auto Tier Switching" in Rebirth > Auto RB Customize > Auto Tier Switching Settings

• Changed: Rebirth Point Gain from Town [Temple] is now multiplicative

• Fixed a bug where Passive Heroes could become stuck inside a Dungeon when WA was performed during Auto Dungeon Progression. With this patch, if WA is executed while ADP is in progress, all heroes will move to their Favorite Area after WA. (If "AAP on WA" is enabled, AAP will be executed.)

• Fixed: Other minor bugs
