➢Did many investigation from
the very early stage like mid
2015
➢Limitless draw calls and
render passes now allowed in
mobile product
➢It gives real gains like 2X
FPS with some scenes
Super efficient
Why Vulkan?

➢More performance or less
power / thermal
➢More visual effect and post
processing can be covered
within same hardware
resources
➢Various explicit ways to
optimize application
➢Means you can make your
game runs faster and look
better

➢Providing information at the right time
➢Predictable performance costs
• Creating pipelines, allocating memory, more…
➢No driver magic on the clock
• Remove guesswork and late decision making
➢Simpler drivers
➢Better scheduling over CPU & GPU work
What it is?
Explicit API

➢Low-level == Thin layer over specific HW implementation, little abstraction
• Not possible given wide variety of hardware
➢Making everything the app’s problem
➢Getting the driver out of the way
➢Solves a different problem than we were asked to
What it is not?

➢Strong desire to avoid forking the
ecosystem
➢A single API(desktop, mobile)
➢Supports various GPU
hardware(IMR, TBR, TBDR)
PortabilityWrite once, run anywhere

➢Scenarios to reconsider coding to Vulkan
• Need to compatibility to pre-Vulkan platform
• Heavily CPU-bound application due to non-graphics work
• Single-threaded application, unlikely to change
• App can target middle-ware engine, avoiding 3D graphics
API dependencies(Consider using an engine targeting
Vulkan, instead of coding Vulkan yourself)

Why Vulkan is good for Unity?
• Not low-level, but explicit API
- Lots of the responsibility shifted to the developer
- Not a beginner’s graphics API!
• Allows multithreaded rendering
• Supported in Unity 5.6 and later on Android, Win, Linux
- ”Experimental” on Win and Linux due to no editor support (yet)
![Page 25: Vulkan Game Development · Vulkan Game Development Unity x Samsung. Contents - Introduce Vulkan 1.Introductions 2.Vulkan is 3.Why Vulkan 4.Explicit API 5.Portability ...

1. Go to Player Settings inspector
2. Uncheck ”Auto Graphics API”
3. Click ’+’, add Vulkan to the list
4. Drag Vulkan to the top of the list
5. Profit!
Enabling Vulkan in Unity
![Page 26: Vulkan Game Development · Vulkan Game Development Unity x Samsung. Contents - Introduce Vulkan 1.Introductions 2.Vulkan is 3.Why Vulkan 4.Explicit API 5.Portability ... Unity Games](https://reader036.fdocuments.net/reader036/viewer/2022062415/603dd0908dc2c401c7708310/html5/thumbnails/26.jpg)
• None!
• Actually, a choice between:
- More eye candy on the screen “for free”, or:
- Longer battery life
• Draw calls are “almost free” in Vulkan
- State changes, texture/geometry upload etc has a cost
- Means more animated stuff on screen at the same time
• Not a magic bullet!
- GPU still has to draw the same pixels!
Special considerations

Vulkan benefits
• “Zero Driver Overhead”
• Fine-grained control over the GPU
• No need to fight drivers attempting (and failing) to be smart
• “No surprises”
• Queue submits, flushes, uploads etc. happen exactly when we say so.
• No surprise shader recompilations
