# SEngine Graphics Upgrade

This FAQ explains **SEngine**, our proprietary in-house engine, and the graphics upgrade it brings to the game. SEngine has now reached its **1.0 stable release** after an extended polishing and testing phase.

## What is SEngine?

SEngine is a proprietary engine built in-house specifically for our project and our long-term goals. It is not an off-the-shelf engine. It was designed from the ground up to fit this game and where we want to take it in the future.

## What changed compared to the old engine?

The game originally ran on a **DirectX 9** based engine. SEngine moves the game onto a new **DirectX 11** foundation. This is a major step that lets us push the game's visuals, performance, and technical possibilities further than the old engine allowed.

## What is the goal of SEngine?

The goal is to bring the game's graphics and presentation closer to the level expected from modern engines like Unreal Engine, while staying realistic about the differences in budget, team size, and resources. This is not a large studio project with dozens of engineers; it is developed by a **solo developer**, which makes every step challenging but also meaningful.

## Is SEngine stable? Can I use it now?

Yes. SEngine has reached its **1.0 stable release**. During development, players helped test the engine and the results were very positive. That testing phase fed directly into polishing stability and tuning visual quality for the stable build.

## What graphics features does SEngine add?

The DirectX 11 foundation unlocks a range of modern rendering features that were not possible on the old engine:

- **Real-time shadows**
- **Emissive materials**
- **Scene glow**
- **Advanced sky** with weather support
- **Film FX**
- **HDR**
- **SSAO** (Screen Space Ambient Occlusion)
- **FXAA anti-aliasing**
- **Bloom**
- **Advanced lighting** (SSRTGI hemispheric lighting)

## Is it faster than the old engine?

Yes. On some computers, SEngine runs around **230% faster** than the old DirectX 9 engine, while also rendering the new visual features above. Actual gains depend on your hardware.

## What are the system requirements?

Because SEngine moves the game onto a DirectX 11 foundation, the minimum system requirements have increased compared to the old DirectX 9 engine. These are the new minimums for VSky-X:

### 🟢 Minimum (plays at Low settings)

- **OS**: Windows 10 64-bit
- **CPU**: Pentium III 800 MHz
- **RAM**: 1 GB
- **GPU**: DirectX 11 compatible GPU with 512 MB VRAM
- **Pixel Shader**: 5.0
- **Vertex Shader**: 5.0
- **Storage**: ~15 GB (SSD recommended)

The key requirement is a **DirectX 11 compatible GPU**. Older cards that only support DirectX 9 will no longer be able to run the game.

## Will there be more updates?

Yes. Reaching 1.0 stable is a milestone, not the finish line. Work continues on:

- Polishing the engine and improving stability
- Adjusting and improving visual quality
- Gradually adding more features

SEngine is not just a technical upgrade. It is the foundation for the future of the project and this game, so it will keep evolving over time.

## Who develops SEngine?

SEngine is developed by a single solo developer. Progress reflects the time and effort of one person, with help from community testers who volunteered during the testing phase.
