NVIDIA® SLI® & PhysX®
Desktop UI UsabilitySLI technology intelligently scale graphics performance by combining multiple NVIDIA graphics processing units (GPUs).
PhysX technology is a physics simulation engine that adds an element of realism to games, providing dynamic effects like blazing explosions, reactive debris, realistic water, and lifelike characters.

- Alignment & dependencies with rest of the product
Persona
Brainstorming & Conceptual Design
1. Configuration Options
2. System Setup
Enumerating possible setup and preferred configurations.
Graphical representation of the system for showing the preview so users know before they commit to any change.
Design
1. Configuration Options
- Goal oriented presets for SLI configuration
- Defined algorithm for each of the presets
- Flexible PhysX options
- User can choose auto-select or pick any GPU or CPU
2. System Setup
- Real-time system status, shows preview for any options changed in the UI
- Helping user minimize plugging/unplugging of the monitors
- Users can make informed decision before applying
- Providing suggestions and information for troubleshoot the issues
User Interface
- Produced UI layout specifications
- Provided interaction details, including keyboard navigation
- Defined flow for each of the presets
- Documentated all the resources, UI Text, Images, Icons etc.
- Worked with UI Engineers to implement the interface
- Helped engineering team to design the desired behavior
- Supported QA in defining test plans and configurations

In-game Visual Indicators
For power users and troubleshooting.
Shows the status of SLI and PhysX while the game is running.
Product Reviews
- Checkout the SLI setup review with UI screenshot at NinjaLane, Geeks3D and Guru3D.
- Graphic-representation of the system is extremely popular in the users. They use it when posting on online forums about general system issues. Check out posts at EVGA, Bit-Tech and TomsHardware (scroll-down to see).
PhysX demo - observe the flying debris, smoke, things moved by wind etc.
