Calliope is moving from DirectX 9 to DirectX 11!

We have prepared one of the most important technical upgrades ever made to the Calliope client: the transition of the graphics engine from DirectX 9 to DirectX 11.

This upgrade is far more than a simple version change. DirectX 11 allows the CPU and graphics card to handle characters, effects, shadows, and multiple objects displayed simultaneously much more efficiently. This reduces the bottlenecks of the old DirectX 9 engine, which limited performance especially in heavily populated areas.

Initial tests already show a tremendous difference:

- Significantly higher and more stable FPS
- Far fewer FPS drops in cities and crowded areas
- More efficient rendering of players, monsters, and effects
- Better utilization of modern hardware
- Superior image quality
- A modern graphics foundation for future improvements

The most important result is not simply reaching an extremely high number of frames per second, but maintaining a smooth experience when numerous players, shops, monsters, and effects are displayed on screen > the exact situations where DirectX 9 showed its limitations most clearly.

Results may vary depending on each system’s configuration, but the difference observed during our tests has been enormous, reaching up to 1000 FPS.

Calliope continues to evolve: modern performance, improved image quality, and smoother battles—even in the most crowded areas.

- Pets and Pet Boxes now display pet skill levels (1-20) and remaining lifetime.
- You can now reset the Resistance skill separately from the Help skill.
- Aura of the Sword and other similar skills now have an active duration of **60 hours** (previously 6).
- You can now purchase a **10% Energy Crystal (30 Days)** from the Alchemist using regular **7%-10% Energy Crystals**.
- The NPC sell price of upgrade items has been reduced (to maintain a healthier balance between Yang generation and Yang removal).
- The Yang cost of the Switchbot has been increased (for the same reason).
- The Switchbot bonus rates have been increased for **items and sashes** (talismans are not affected). This change is intended to improve the overall gameplay experience.
- In Warzone, **Warriors** now receive more Yang per kill. This adjustment compensates for the disadvantages of melee combat against ranged classes.
- Event notifications will not be displayed while Auto Farm is active.
- Chat messages will pause while the chat window is open, making them easier to read.
- New item: Perso Tag Transfer.
- Removed the confirmation message when equipping or unequipping the Rookie Medal.
- You can now link items directly from your personal shop into chat.
- Crescent Moon Rings and Lollipops can now be stacked.
- HP Elixirs can no longer be used inside the Warzone map.
- Removed the Ninja Archer range and damage reduction previously active in Warzone.
- Players now receive Yang for every kill in Warzone. The reward is dynamically adjusted based on class, with non-Shaman classes generally receiving higher rewards (to compensate for differences in kill potential). Since Shamans naturally achieve the highest kill counts in Warzone, this change encourages greater class diversity. A similar system has already proven successful during the Tanaka event.
- All existing Warzone rewards remain unchanged. The Yang-per-kill reward is an additional bonus on top of the current reward structure to encourage more classes to participate.
- The Anti Kill-Steal system has been re-enabled in Warzone.

Pet Evolution System Improvements

We updated the pet evolution system to make high-level progression more satisfying and less frustrating.

🔹 Early levels keep the classic style (0.1% - 0.6%)
🔹 Starting from level 80, pets can no longer receive extremely low rolls. (0.3% - 0.6%)
🔹 Starting from level 110, progression becomes even more stable. (0.4% - 0.6%)

This means:
🔹 Fewer “ruined” pets in late game
🔹 More consistent progression
🔹 Easier to obtain good 13~14% pets
🔹 Perfect pets remain rare and valuable

The goal was NOT to make perfect pets common, but to reduce the frustration of wasting a lot of time because of very weak rolls when a pet looked promising at a certain level.

Extra:
🔹 The system now automatically uses Blue Books for level-up.
🔹 The evolution prediction system was adjusted to reflect pet progression more realistically.
