Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a large number of task-specific shaders are prepared for the GPU, then rendering precision and task specificity are improved, but memory capacity is exceeded and shaders cannot be pre-loaded
Solution Approach 1:
The system performs preliminary actions by predicting future gameplay events and pre-loading required shaders into GPU memory before they are actually needed. This allows the system to have shaders ready in advance without needing to load all possible shaders simultaneously, thus maintaining rendering precision while managing memory capacity effectively.
Solution Approach 2:
The shader loading system transitions from a static approach (pre-loading all shaders or loading on-demand) to a dynamic approach where shaders are predicted and loaded based on anticipated gameplay events. This dynamic system adjusts shader loading in real-time based on game state, improving both rendering precision and memory utilization.
2Quantity of substance
If shaders are loaded as and when required, then memory usage is optimized, but processing delays and performance issues occur
Solution Approach 1:
Instead of loading shaders only when required (which causes delays), the system performs preliminary actions by predicting which shaders will be needed soon and loading them in advance. This eliminates processing delays while maintaining optimized memory usage through selective pre-loading rather than loading all shaders at once.
Solution Approach 2:
The system uses gameplay event data and machine learning models to autonomously predict and load required shaders without external intervention. This self-service approach continuously monitors game state and proactively manages shader loading, reducing processing delays while maintaining efficient memory utilization.
3Reliability
If PC compiles shaders during initialization, then shader availability is improved, but noticeable delays occur during gameplay
Solution Approach 1:
The system performs shader compilation and loading as a preliminary action during game initialization, but enhances this by using prediction to load only the shaders that will actually be needed soon. This ensures shader availability while minimizing compilation and loading delays compared to compiling all possible shaders.
Solution Approach 2:
Instead of compiling and loading all possible shaders (excessive action), the system compiles and loads only the subset of shaders predicted to be needed for upcoming gameplay events (partial action). This partial approach maintains shader availability while significantly reducing compilation delays during initialization.
4Reliability
If gaming console pre-compiles all shaders prior to runtime, then shader availability is improved, but memory loading delays occur during gameplay
Solution Approach 1:
The system performs preliminary shader compilation during game development (forming part of game data), but enhances the pre-runtime approach by using prediction to load only the specific shaders needed for upcoming gameplay events. This maintains shader availability while eliminating the loading delays that occur when pre-compiling all shaders.
Solution Approach 2:
The system transitions from a static pre-compilation approach (where all shaders are compiled and must be loaded) to a dynamic prediction-based approach. Shaders are compiled in advance during development, but only the predicted necessary shaders are loaded into GPU memory, dynamically adjusting to game state and eliminating loading delays.
