Regarding our previous announcement that the game would support only CPUs with AVX2 or later, we have received multiple requests for support of AVX (such as Sandy Bridge generation). We would like to take this opportunity to offer a renewed explanation and our apologies.
Why the Game Supports Only AVX2 or Later
Our game incorporates numerous features and effects that require advanced computational processing. To ensure these features operate smoothly, we have optimized performance with the AVX2 instruction set in mind.
AVX2 (Advanced Vector Extensions 2)
An instruction set fully supported starting with CPUs introduced around 2013 (Haswell generation).
By improving the efficiency of simulation processing and graphics processing, AVX2 significantly contributes to faster and more stable gameplay.
AVX (Advanced Vector Extensions)
An earlier extension introduced around 2011 (Sandy Bridge generation).
While it can provide some level of speedup as AVX2’s predecessor, the corresponding CPUs are older. As a result, in many cases overall performance does not meet the demands of current gaming requirements.
Background on Considering AVX Support
We received customer feedback requesting “AVX support,” and we conducted official testing within our company.
However, we concluded that AVX-compatible CPUs (from around 2011) lack sufficient performance for the high-level computations required by the game, making it difficult to ensure a comfortable playing experience.
Testing Results
Significant slowdowns or marked frame rate reductions in certain situations
A high possibility of unstable gameplay progression
Even if it runs temporarily, stable service delivery is not guaranteed
Reason We Concluded We Cannot Fulfill This Request
If we were to redesign the game around AVX-compatible machines, we would have to significantly reduce graphics quality and processing content to lower overall computational load. Unfortunately, such changes could also affect many players already enjoying the game on AVX2 and later environments, leading us to conclude that supporting AVX-only environments would be unfeasible.
Degradation of Game Quality
Adapting to the performance levels of AVX would require extensive optimization and resource reduction. This would risk compromising the game’s appeal and overall quality.
Increased Complexity in Support Coverage
Providing and maintaining multiple versions for different instruction sets would introduce significant risks and costs with each update or bug fix.
Request and Apology to Our Customers
We sincerely apologize to customers who desired AVX support for not being able to meet your expectations.
In order to operate the game stably and continue providing enjoyable content, we ask for your understanding that our recommended operating environment will be CPUs with AVX2 or later.
Future Updates and Ongoing Efforts to Improve Our Service
We take your feedback seriously and will continue to optimize and improve the game so that it can be enjoyed on as wide a range of environments as possible.
We deeply apologize for any inconvenience this may cause and appreciate your understanding.
Thank you very much for your continued support. We look forward to providing you with an enjoyable gaming experience in the future.
